QUESTION 1How can you "throttle" SnapValue updates and baseline transfers so that the primary or secondary is nottransmitting data as it can?

A. Use the -k option in the snapvault start or snapshot modify commands.B. SnapVault does not support throttling of network throughout.C. Use the snapvault throttle command.D. Use the -k option in the snapvault initialize command.

Correct Answer: DSection: (none)Explanation

Explanation/Reference:Explanation:http://backdrift.org/man/netapp/man1/na_snapvault.1.html The snapvault subcommands are:start [ -r ] [ -k n ] [ -t n ] [ -w ] [-p {inet | inet6 unspec}] [ -o options ] [ -S [primary_filer:]primary_path ]secondary_qtreemodify [ -k n ] [ -t n ] [-p {inet | inet6 | unspec}] [ -o options ] [ -S primary_filer:primary_path ] sec_ondary_qtree

The -k option sets the maximum speed at which data is transferred in kilobytes per second. It is used tothrottledisk, CPU, and network usage. If this option is not set, the filer transmits data as fast as it can. Thesettingapplies to the initial transfer as well as subsequent update transfers from the primary.

QUESTION 2Node 1 in a clustered pair detects that it has lost connectivity to one of its disk shelves. Node 1 is still up, but itcannot see one of its disk shelves. However, the partner node, Node 2, can see all of the Node 1's diskshelves. Which feature will cause Node 2 to monitor this error condition for a period of three minutes by default,and then forcibly take over Node 1 if the error condition persists?

A. Auto enable of givebackB. Negotiated Fail OverC. Takeover on panicD. Cf.quickloop.enable

Correct Answer: BSection: (none)Explanation

Explanation/Reference:

Explanation:http://www.wafl.co.uk/cf/http://wafl.co.uk/options/Negotiated failover is a general facility which supports negotiated failover on the basis of decisionsmade byvarious modules.

cf.takeover.on_disk_shelf_miscompareThis option allows negotiated takeover to be enabledwhen the cluster nodes detect a mismatch in diskshelfcount. By default, this option is set to off.

This option is available only when cluster is licensedand changing the value on one filer automaticallychangesthe value on the partner filer.

If a disk fails and no hot spare disk that exactly matches the failed disk is available, Data ONTAP uses thebestavailable spare. Understanding how Data ONTAP chooses an appropriate spare when there is nomatchingspare enables you to optimize your spare allocation for your environment.

Data ONTAP picks a non-matching hot spare based on the following criteria (and more; in the link above):If the available hot spares are not the correct size, Data ONTAP uses one that is the next size up, ifthere is one.The replacement disk is downsized (aka right sized) to match the size of the disk it is replacing; theextracapacity is not available.

QUESTION 6Which statement is true about expanding an aggregate from 32-bit to 64-bit in place?


A. All aggregates are automatically converted from 32-bit to 64-bit with the Data ONTAP 8.1 upgrade.B. The expansion is triggered by an aggr convert command.C. The expansion is triggered by adding disks to exceed 16 TB.D. The 32-bit aggregates are degraded and must be Volume SnapMirrored to a new 64-bit aggregates with

Data ONTAP 8.1 upgrade.

Correct Answer: CSection: (none)Explanation

Explanation/Reference:Explanation:http://www.ntapgeek.com/2011/12/how-in-place-expansion-works.html To upgrade an aggregate in-place, theonly available method is to add disks to expand the aggregate to>16TB.

QUESTION 7What utility on the storage system will allow you to capture network packet information?

A. SnoopB. NetstatsC. PkttD. Traceroute


Explanation/Reference:Explanation:The pktt command controls a simple on-filer packet tracing facility. Packets can be captured into a tracebufferthen dumped to a file, or the captured data can be logged to a file. The data is stored in "tcpdump"format, and

can be directly viewed with tcpdump, ethereal, and perhaps other viewers. The output can also beconvertedusing the editcap(1) program to a variety of other formats, including Sniffer, NetMon, and snoop.

QUESTION 8The root admin on the UNIX box receives an "Access Denied" message when he attempts to access a newlymounted qtree. What's the most likely cause of this error?

A. The qtree is missing from the /etc/hosts file.B. NFS is turned off on the storage system.C. The qtree is set to ntfs security style.D. The qtree has not been exported.


Explanation/Reference:Explanation:http://hd.kvsconsulting.us/netappdoc/801docs/html/ontap/smg/GUID-866DD79D-D2A6-4FBA-B0BDA63560FECEFF.html

Only hostnames and IPs are referenced in /etc/hosts, so A is incorrect. Thequestionstates that the qtreewasmounted, and B and D would preclude this so they are incorrect. You need to set a qtree to mixed or unixsecurity style to support UNIX users.

QUESTION 9Which two modes support using SnapMirror over multiple network paths?

A. StandaloneB. PartnerC. MultiD. FailoverE. Give back

Correct Answer: CDSection: (none)Explanation

Explanation/Reference:Explanation:https://library.netapp.com/ecmdocs/ECMP1196991/html/GUID-75BD4540-A103-4E2B-8B0A-E6BBC0D3F43F.htmlhttp://backdrift.org/man/netapp/man5/na_snapmirror.conf.5.html

Two multipath methods are supported:The multiplexing mode causes snapmirror to use both paths at the same time. If one should fail, it will switchtouse the remaining path only and use both again should the failing path be repaired. Failover mode causessnapmirror to use the first path as the desired path and only use the second pathshould problems arise with thefirst path.

QUESTION 10Identify the two commands that could be entered on the SnapMirror destination storage system.(Choose two)

A. Options snapmirror.access onB. Options snapmirror.resync onC. Snapmirror initializeD. Snap mirror resync


Explanation/Reference:Explanation:https://library.netapp.com/ecmdocs/ECMP1196979/html/man1/na_snapmirror.1.html snapmirror initialize [ -Ssource ] [ -k kilobytes ] [ -s src_snap ] [ -c create_dest_snap ] [ -w ] destinationStarts an initial transfer over thenetwork. An initial transfer is required before update transfers can take place.

The initialize command must be issued on the destination node. If the destination is a volume, it mustberestricted (see na_vol(1) for information on how to examine and restrict volumes). If the destination is aqtree, itmust not already exist (see na_qtree(1) for information on how to list qtrees). If a qtree already exists, itmustbe renamed or removed (using an NFS or CIFS client), or snapmirror initialize to that qtree will not work.snapmirror resync [ -n ] [ -f ] [ -S source ] [ -k kilobytes ] [ -s src_snap ] [ -c create_dest_snap ] [ -w ]destinationResynchronizes a broken-off destination to its former source, putting the destination in thesnapmirrored stateand making it ready for update transfers. The resync command must be issued on thedestination node.

QUESTION 11Which two operations can be performed with the SnapDrive for windows graphical user interface?

A. Create volumeB. Create Snapshot copiesC. Create FileD. Create Disk

Correct Answer: BDSection: (none)Explanation

Explanation/Reference:Explanation:https://library.netapp.com/ecm/ecm_download_file/ECMM1278920

What SnapDrive doesSnapDrive software integrates with the Windows Volume Manager so that NetApp filers can serve asvirtualstorage devices for application data in Windows 2000 Server and Windows Server 2003 environments.

SnapDrive is dependent on the virtual disk service. The virtual disk service must be started on the host priortoinstalling SnapDrive. SnapDrive manages virtual disks (LUNs) on a NetApp filer, making these virtualdisksavailable as local disks on Windows hosts. This allows Windows hosts tointeract with the virtual disks justas if they belonged to a directly attached redundant array of independentdisks (RAID).

SnapDrive provides the following additional features:It enables online storage configuration, virtual disk expansion, and streamlined management. It integratesNetApp Snapshot technology, which creates point-in-time images of data stored on virtualdisks.It works in conjunction with SnapMirror® software to facilitate disaster recovery from either asynchronouslyorsynchronously mirrored destination volumes.

https://library.netapp.com/ecmdocs/ECMP1196979/html/man1/na_snapmirror.1.html https://library.netapp.com/ecmdocs/ECMP1196979/html/man5/na_snapmirror.conf.5.html snapmirror update [ -S source ] [ -k kilobytes ][ -s src_snap ] [ -c create_dest_snap ] [ -w ] destinationFor asynchronous mirrors, an update is immediately started from the source to the destination to updatethemirror with the contents of the source.

For synchronous mirrors, a snapshot is created on the source volume which becomes visible to clients ofthedestination volume.

The snapmirror update command must be issued on the destination filer. snapmirror release source{ filer:volume | filer:qtree } Tell SnapMirror that a certain direct mirror is no longer going to request updates. If acertain destination is no longer going to request updates, you must tell SnapMirror so that it will no longerretaina snapshot for that destination. This command will remove snapshots that are no longer needed forreplicationto that destination, and can be used to clean up SnapMirror- created snapshots after snapmirrorbreak is issuedon the destination side.

The source argument is the source volume or qtree that the destination is to be released from. Thedestinationargument should be either the destination filer and destination volume name or the destination fileranddestination qtree path. You can use a line from the output of the snapmirror destinations command as thesetof arguments to this command.The /etc/snapmirror.conf file exists on the node containing the mirror used forSnapMirror.

QUESTION 15You are trying to do a single file SnapRestore for a file, but you are receiving an error message that thedirectory structure no longer exists. Which is the most likely explanation?

A. Once the directory structure has been deleted, you cannot restore the file using single file SnapRestore.You must now SnapRestore the volume.

B. Snapshot copies have been created since the original directory structure was deleted.C. You must recreate the directory structure before trying to restore the file.D. You cannot restore a file to an alternate location.


Explanation/Reference:Explanation:https://library.netapp.com/ecmdocs/ECMP1196991/html/GUID-35C9A4BA-02BA-4965-A366-698C1299E29D.html

You can restore a file only to the volume where it was originally located. The directory structure to which a fileisto be restored must be the same as that specified in the path. If this directory structure does not exist, youmustcreate it before restoring the file.

QUESTION 25Which two cp types would indicate a busy storage system? (Choose two).

A. cp_from_log_fullB. cp_from_busyC. cp_from_cpD. cp_from_timer


Explanation/Reference:Explanation:http://backdrift.org/man/netapp/man1/na_sysstat.1.html http://redhunter.com/blog/2010/02/11/netapp-

consistency-points-in-cacti/ cp_from_log_full (log full) - the current NVRAM bank is full and the system switchesto the other one andstarts writing this to disk. Very heavy write activity.

cp_from_cp (aka Back to Back) - filer is overloaded. The write traffic is coming in faster than it can bewrittenand the filer is running out of NVRAM capacity in one bank before the data in the other bank can bewritten.

cp_from_busy is not a real cp typecp_from_timer - 10 seconds since the last CP it means the system is pretty idle write-wise.

QUESTION 26There are three phases of Non Disruptive Volume Movement (NDVM). What is the correct sequence of thesephases?

A. Setup Phase, Mirror Phase, Cutover PhaseB. Initialization phase, Copy Phase, Migrate PhaseC. Begin Phase, Move Phase, Complete PhaseD. Setup Phase, Data Copy Phase, Cutover Phase


Explanation/Reference:Explanation:https://communities.netapp.com/servlet/JiveServlet/previewBody/9734-102-1- 17848/PDF_Tips_Data_Motion_0211.pdf

QUESTION 27Which statement describes the results of the SnapMirror resynce command?

A. Resynchronization finds the newest common snapshot shared by the two volumes or qtree, and removes allnewer information on the storage system on which the command is run.

B. Resynchronization will cause the loss of all data written to the destination after the original base snapshot was made.

C. Resynchronization will update the snapshot on the destination filer.D. Resynchronization will update the snapshot on the source filer.


Explanation/Reference:Explanation:https://library.netapp.com/ecmdocs/ECMP1196979/html/man1/na_snapmirror.1.html

snapmirror resync[ -n ] [ -f ] [ -S source ] [ -k kilobytes ] [ -s src_snap ] [ -c create_dest_snap ] [ -w ] destinationResynchronizes a broken-off destination to its former source, putting the destination in the snapmirroredstateand making it ready for update transfers. The resync command must be issued on the destination node.

The resync command can cause data loss on the destination. Because it is effectively makingdestination a

replica of the source, any edits made to the destination after the break will be undone.

For formerly mirrored volumes, the resync command effectively performs a SnapRestore (see na_vol(1)) on the destination to the newest snapshot which is common to both the source and thedestination. In mostcases, this is the last snapshot transferred from the source to the destination, butit can be any snapshot whichis on both the source and destination due to SnapMirror replication. Ifnew data has been written to thedestination since the newest common snapshot was created, thatdata will be lost during the resync operation.

QUESTION 28If you were troubleshooting and wanted to look at SnapMirror log files, what is the path to these files?

A. /vol/vol0/etc/log/snaplog/B. /vol/vol0/etc/snapmirror/C. /vol/vol0/etc/snaplog/D. /vol/vol0/etc/log/



The root volume is always vol0 and etc is contained therein. When exporting the root volume via NFS, thepathis/vol/vol0; so the full path to snapmirror log files is /vol/vol0/etc/log./etc/log/snapmirror.

This file logs SnapMirror activity. Log file for current week. /etc/log/snapmirror.[0-5]SnapMirror log files forprevious weeks.

QUESTION 29Host multi-pathing describes a ____________ solution that has at least two distinct ______________ paths to aLUN.

A. Token ring, physicalB. FC SAN, virtualC. FC or IP SAN, virtualD. FC or IP SAN, Physical


Explanation/Reference:Explanation:http://en.wikipedia.org/wiki/Multipath_I/OFiber Channel (FC), FCoE and iSCSI encapsulate SCSI-3. FCoE and iSCSI further encapsulate thetransportwithin IP; hence the term IP SAN.

In computer storage, multipath I/O is a fault-tolerance and performance enhancement technique wherebythereis more than one physical path between the CPU in a computer system and its mass storage devicesthroughthe buses, controllers, switches, and bridge devices connecting them.

A simple example would be a SCSI disk connected to two SCSI controllers on the same computer or adiskconnected to two Fibre Channel ports. Should one controller, port or switch fail, the operating system canrouteI/O through the remaining controller transparently to the application, with no changes visible to theapplications,other than perhaps incremental latency.

QUESTION 30Which two will allow you to read and analyze a packet trace file generated by the storage system? (Choosetwo)

A. WireSharkB. PkttC. NetmonD. Eternal View

Wireshark is the successor of Etherreal, and available for several platforms. Netmon is a Microsoftproject,available for Windows, soon to be deprecated by the Microsoft Message Analyzer project.

QUESTION 31How does the NetApp Remote Agent (RSA) connect to NetApp Support?

A. NetApp Support initiates a non-secure connection to the RSA.B. NetApp Support initiates a secure connection to the RSA.C. The RSA initiates a secure connection to NetApp Support.D. The RSA initiates a non-secure connection to NetApp support.


Explanation/Reference:Explanation:https://library.netapp.com/ecm/ecm_download_file/ECMP1200040

Remote Support Agent is the facility to provide NetApp Support Engineers with the ability to remotelytriggerAutoSupport.

Remote Support Agent uses HTTP or HTTPS to communicate with the storage controller to initiatecommandsand to collect files. It uses HTTPS to send system logs and core files from the Data ONTAP rootvolumeto Remote Support Enterprise on the NetApp Support side. NetApp RSA is not related to the RSA publickey encryption algorithm.

QUESTION 32

Which two commands can be used to enable LUN reservations? (Choose two)

A. lun set reservationB. lun reservation setC. lun mapD. lun create


Explanation/Reference:Explanation:https://library.netapp.com/ecmdocs/ECMP1196979/html/man1/na_lun.1.html

lun set reservation lun_path [ enable | disable ]Enables or disables the space reservation on the LUN. If no arguments are supplied after the lun_path, thenthespace reservation status of the given lun_path is displayed. lun create -s size -t ostype [ -o noreserve ] [ -espace_alloc ] lun_path This usage of the lun create command should be employed to create a new LUN ofgiven size, with initiallyzero contents. The LUN is created at the lun_path given. No file should already exist atthe given lun_path. Thedirectory specified in the lun_path must be a qtree root directory.

The size is specified in bytes. Optionally, a number followed by a one-character multiplier suffix can be used: c(1), w (2), b (512), k (1024), m (k*k), g (k*m), t (m*m).

The size of the created LUN could be larger than the size specified, in order to get an integral numberofcylinders while reporting the geometry using SAN protocols.

The size of the LUN actually created is reported if it is different from that specified in the command.The mandatory ostype argument is one of: solaris (the LUN will be used to store a Solaris raw disk in asingleslicepartition), windows (the LUN will be used to store a raw disk device in a single- partition Windowsdiskusing the MBR (Master Boot Record) partitioning style), hpux (the LUN will be used to store HP-UX data),aix(the LUN will be used to store AIX data), vld (the LUN contains a SnapManager VLD), linux (the LUN willbeused to store a Linux raw disk without any partition table), netware (the LUN will be used to storeNetWaredata), vmware (the LUN will be used to store VMware data), windows_gpt (the LUN will be used tostoreWindows data using the GPT (GUID Partition Type) partitioning style), windows_2008 (the LUN will beused tostore Windows data for Windows 2008 systems), openvms (the LUN will be used to store Open-VMSdata),xen (the LUN will be used to store Xen data), hyper_v (the LUN will be used to store Hyper-V data),solaris_efi

By default, the LUN is space-reserved. To manage space usage manually, -o noreserve can be specified.

"Pass Any Exam. Any Time." - www.actualtests.com 21Network Appliance NS0-155 Exam

Using this option will create a LUN without any space being reserved. Provisioning threshold events canbeenabled by specifying -e space_alloc option. This option has to be used in conjunction with -o noreserve.

lun map [ -f ] lun_path initiator_group [ lun_id ]Maps a LUN to all the initiators in the supplied group. If a LUN ID is not specified, the smallest number thatcanbe used for the various initiators in the group is automatically picked. Note that this command can beusedmultiple times to configure multiple maps for a LUN, or for an initiator group. Once created, you can uselunshow -m to list all the LUN mappings. The optional -f argument disables checking with the HA partner forLUN mapping conflicts.

QUESTION 33Which Data ONTAP option sets system-wide for all transfers?

A. Options transfers.wide.enableB. Options transfer.throttle.enable.C. Option replication.wide.enableD. Options replication.throttle.enable

Correct Answer: DSection: (none)

Explanation

Explanation/Reference:Explanation:https://library.netapp.com/ecmdocs/ECMP1196979/html/man1/na_options.1.html

replication.throttle.enableEnables global network throttling of SnapMirror and SnapVault transfers.The default value for this option isoff.replication.throttle.incoming.max_kbsThis option specifies the maximum total bandwidth used by all the incoming (applied at destination)SnapMirrorand SnapVault transfers, specified in kilobytes/sec. The default value for this option is unlimited,which meansthere is no limit on total bandwidth used. This option is valid only when the optionreplication.throttle.enable ison.

replication.throttle.outgoing.max_kbsThis option specifies the maximum total bandwidth used by all the outgoing (applied at source) SnapMirrorandSnapVault transfers specified in kilobytes/sec. The default value for this option is unlimited, which meansthereis no limit on total bandwidth used. This option is valid only when the option replication.throttle.enable ison.

QUESTION 34What is the correct format for the scheduling component of a SnapVault schedule?

A. cnt[@day_list][@hour_list]B. YYYY-MM-DDC. Crontable formatD. List of dates in ISO Date format


Explanation/Reference:Explanation:https://library.netapp.com/ecmdocs/ECMP1196979/html/man1/na_snapvault.1.html http://www.geekyfacts.com/index.php?option=com_content&view=article&id=64:snapvault snapvault snap sched [ -f ] [ -x ] [ -o options ][ volname [ snapname [ schedule]]] schedule is cnt[@day_list][@hour_list] or cnt[@hour_list][@day_list] In theschedule, cnt tells SnapVault how many of the snapshots to keep for primaries and for non-SnapLocksecondary volumes. The snapshots will be numbered newest to oldest from 0 to cnt-1. When creatinga newsnapshot, SnapVault will delete the oldest snapshots, increment by one the number on theremainingsnapshots and then create a new number 0 snapshot. If a snapshot is missing from the sequence(e.g. sv.0,sv.1, and sv.3 exist but sv.2 does not), only snapshots that need to be renumbered to make room forthe newsv.0 snapshot will be renumbered. In the example, sv.0 and sv.1 would be renamed to sv.1 and sv.2,but sv.3would remain unchanged.

The cnt in the schedule is interpreted differently for SnapVault secondary SnapLock volumes. ForSnapLocksecondary volumes, snapshots are created with a name that includes an encoded date and time ofwhen thesnapshot is created. These snapshots are never renamed and they are never automatically deleted.Thesesnapshots may be deleted using snap delete after the retention period of the snapshot has expired. If cntis 0,no snapshots will be taken. If cnt is any non-zero value, snapshots will be taken and no snapshots willbeautomatically deleted.

If specified, the day_list specifies which days of the week the snapshot should be created. The day_list isacomma-separated list of the first three letters of the day: mon, tue, wed, thu, fri, sat, sun. The names arenotcase sensitive. Day ranges such as mon-fri can also be given. The default day_list is mon-sun, i.e. everyday.

If specified, the hour_list specifies which hours of the day the snapshot should be created, on each

scheduledday. The hour_list is a comma-separated list of the hours during the day, where hours are integersfrom 0 to23. Hour ranges such as 8-17 are allowed. Also, step values are allowed in conjuction with ranges.Forexample, 0-23/2 means "every two hours". The default hour_list is 0, i.e. midnight on the morning ofeachscheduled day.

QUESTION 36UNIX allows file access based on___________.

A. NT ACLs and UNIX permissions.B. NT ACLs and SID.C. GID or UID and UNIX permissions.D. GID or UID and ACLs.



In OnTap 8.0, when UNIX security style is selected, only UNIX security objects can be used. The correctansweris GID, UID and UNIX permissions.

Basic UNIX permissions are organized into three classes: user, group, and others. UNIX operating systemsidentify users with a numerical value: a user identifier, also known as a UID or UserID. Each user is a memberof a group of the same name as the user. Like UIDs, groups (GIDs) are alsospecified using a numerical value.

QUESTION 47When using MetroCluster in a forced takeover mode, identify two methods for restricting access to the disastersite node. (Choose two)

A. Use manual fencingB. Use the cf giveback f command.C. Use the cf forcetakeover d command.D. Turn off power to the disaster site node.E. Isolate the failed node from the surviving node.


Explanation/Reference:Explanation:http://vipulvajpayeestorage.blogspot.com/2012/01/manually-failover-activity-in-netapp.html

In order to test or effect a Disaster Recovery operation, you must restrict access to the disaster site nodetoprevent the node from resuming service. If you do not, you risk the possibility of data corruption.

Access to the disaster site note can be restricted in the following ways:Turn off the power to the disaster site nodeUse "manual fencing" (Disconnect VI interconnects and fiberchannel cables; either physically or throughconfiguration changes on the fabric switches.) Isolating the failednode from the surviving node could still lead to the possibility of a split brain, so this is not acorrect answer.

QUESTION 48The two copies SyncMirror volume are called ____________, which are physical copies of the same file systemand consist of one or more RAID groups.

A. Snapshot copiesB. AggregatesC. PlexesD. Volumes


Explanation/Reference:Explanation:https://library.netapp.com/ecmdocs/ECMP1196991/html/GUID-D4D7C7F0-9063-4099-B5CA-8FEE619EEF1D.html

SyncMirror is a feature of Data OnTap used to mirror data to two separate aggregates. It allows for real-timemirroring of data to matching aggregates physically connected to the same storage system.SyncMirror provides for synchronous mirroring of data, implemented at the RAID level. You can useSyncMirrorto create aggregates that consist of two copies of the same WAFL file system. The twocopies,known asplexes, are simultaneously updated. Therefore, the copies are always identical. The two plexes aredirectlyconnected to the same system.

The following provides information about the activities of SyncMirror:SyncMirror can be used to mirror aggregates and traditional volumes. (A traditional volume isessentially anaggregate with a single volume that spans the entire aggregate.) SyncMirror cannot be used to mirror FlexVolvolumes. However, FlexVol volumes can be mirrored as part ofan aggregate.SyncMirror is different from synchronous SnapMirror.

QUESTION 49You want to create an automated test environment that performs a single file SnapRestore time you run theprocedure, however, SnapRestore prompts you to confirm your decision to revert the file. How can youautomate this step?

A. Use the -f option with the snap restore command.B. Enable the options snaprestore_noprompts enable = on option.C. These prompts are for data protection and auditing and cannot be overridden.D. Enter the priv set advanced mode on the storage system and prompt will not appear.


Explanation/Reference:Explanation:https://library.netapp.com/ecmdocs/ECMP1196979/html/man1/na_snap.1.html

snap restore [ -f ] [ -t vol | file ] [ -s snapshot_name ] [ -r restore_as_path ] vol_name | restore_from_path

Reverts a volume to a specified Snapshot copy, or reverts a single file to a revision from a specifiedSnapshotcopy.Before reverting the volume or file, the user is requested to confirm the operation. The -f optionsuppresses thisconfirmation step.

QUESTION 51Five minutes ago, you performed a single file SnapRestore on a large NFS file. 40% of your NFS users are nowcomplaining about getting "stale file handles" for the file. Which is the most likely cause of this problem, and thebest procedure to correct it?

A. This might be due to an NFS storage system and client mismatch. Check to see that these users have thesame version of the NFS client that existed at the time the snapshot was taken.

B. NFS users why try to access a reverted file without first reopening it might get a handle" error message. Have the users try to reopen the file and see if the problem is resolved.

C. After a single file SnapRestore, NFS users have to reboot their systems. Have them reboot their systems.D. These users are on a different subnet from the others. Start troubleshooting by checking their subnet.


Explanation/Reference:Explanation:https://library.netapp.com/ecmdocs/ECMP1196991/html/GUID-35C9A4BA-02BA-4965-A366-698C1299E29D.html

Reverting a file to a selected Snapshot copyUsing snap restore to revert a single file to a selected Snapshot copy is practical when the file is so largethatyou cannot copy the previous file version from the Snapshot copy to the active file system.Before you beginEnsure that you notify the network users before reverting a file so that they know that thecurrent data in the filewill be replaced by that of the selected Snapshot copy.

Note: NFS users who try to access a reverted file without first reopening it might get a stale filehandle errormessage after the volume reversion.

Deduplication is always a post-processed activity forData OnTap, while compression is an inline process.The deduplication schedule depends on the SnapVault update schedule on the destination system.A new Snapshot copy replaces the archival Snapshot copy after deduplication finishes running onthedestination system. (The name of this new Snapshot copy is the same as that of the archival copy, buttheSnapshot copy uses a new timestamp, which is the creation time.) The SnapVault update recognizes thededuplicated blocks as changed blocks. Thus, when deduplication is runon an existing SnapVault source forthe first time, all saved space is transferred to the destination system.

Explanation/Reference:Explanation:https://library.netapp.com/ecmdocs/ECMP1196979/html/man5/na_snapmirror.conf.5.html Each relationshipentry of the /etc/snapmirror.conf file is a single line containing space-separated fields.The entry has this format:Source destination arguments schedulescheduleThis is the schedule used by the destination node for updating the mirror. It informs the SnapMirrorschedulerwhen transfers will be initiated. The schedule field can contain the word sync to specify fullysynchronousmirroring, semi-sync to specify semi-synchronous mirroring, or a cron-style specification of when toupdate themirror.

visibility_intervalThe value for this argument is a number optionally followed by the suffixes: s (seconds), m (minutes) or h(hours). If a suffix is not specified, value is interpreted as seconds. This argument controls the amount oftimebefore an automatic snapshot is created on the source volume that is synchronously mirrored. The value isthenumber of seconds between automatically created snapshots. The default value is 3 minutes. A smallnumberhere can negatively affect the performance of the mirror. This argument is ignored for asynchronousmirrors.

Outstanding (deprecated)This argument controls the performance versus synchronicity trade-off for synchronous mirrors. The valueforthis argument is a number followed by the suffixes: ops (operations), ms (milliseconds) or s (seconds).Settinga value less than 10s configures the mirror to run in fully synchronous mode. Setting a value greaterthan orequal to 10s configures the mirror to run in semi-synchronous mode. This argument is ignoredforasynchronous mirrors. Please note that this is a deprecated option. Use the schedule field to specifythesynchronous mode for the mirror.

cksumThis controls which checksum algorithm is used to protect the data transmitted by SnapMirror.Currentlysupported values are "none", "crc32c", and "crc32c_header_only". The value

"crc32c_header_only" has beenadded only for volume SnapMirror and is not supported for synchronousSnapMirror and qtree SnapMirror.

QUESTION 59Which three attributes would you specify when creating a LUN? (Choose three)

A. The host operating system of the system attached to LUN.B. The version of Data ONTAPC. The size of the LUN.D. The path to the LUN.



The usage for lun create is shown below. Options not in brackets are mandatory. lun create -s size -t ostype [ -onoreserve ] [ -e space_alloc ] lun_path This usage of the lun create command should be employed to create anew LUN of given size, with initiallyzero contents. The LUN is created at the lun_path given. No file shouldalready exist at the given lun_path. Thedirectory specified in the lun_path must be a qtree root directory.

The size is specified in bytes. Optionally, a number followed by a one-character multiplier suffix can be used: c(1), w (2), b (512), k (1024), m (k*k), g (k*m), t (m*m). The size of the created LUN could be larger than the sizespecified, in order to get an integral number ofcylinders while reporting the geometry using SAN protocols.

The size of the LUN actually created is reported if it is different from that specified in the command.The mandatory ostype argument is one of: solaris (the LUN will be used to store a Solaris raw disk in asingleslicepartition), windows (the LUN will be used to store a raw disk device in a single- partition Windowsdiskusing the MBR (Master Boot Record) partitioning style), hpux (the LUN will be used to store HP-UX data),aix(the LUN will be used to store AIX data), vld (the LUN contains a SnapManager VLD), linux (the LUN willbeused to store a Linux raw disk without any partition table), netware (the LUN will be used to storeNetWaredata), vmware (the LUN will be used to store VMware data), windows_gpt (the LUN will be used tostoreWindows data using the GPT (GUID Partition Type) partitioning style), windows_2008 (the LUN will beused tostore Windows data for Windows 2008 systems), openvms (the LUN will be used to store Open-VMSdata),xen (the LUN will be used to store Xen data), hyper_v (the LUN will be used to store Hyper-V data),solaris_efi(the LUN will be used to store Solaris_EFI data).

By default, the LUN is space-reserved. To manage space usage manually, -o noreserve can be specified.Using this option will create a LUN without any space being reserved. Provisioning threshold events canbeenabled by specifying -e space_alloc option. This option has to be used in conjunction with -o noreserve.

For NFS clients, the NFS UID (user id) is mapped to aWindows SID (security identifier) and its associatedgroups. Those mapped credentials are used to determinefile access, based on the NFTS ACL.

QUESTION 13UNIX allows file access based on __________.

A. GID or UID and ACLs.B. GID or UID and UNIX permissions.C. NT ACLs and SID.D. NT ACLs and UNIX permissions.



* Unix-like operating systems identify users within the kernel by an unsigned integer value called a useridentifier, often abbreviated to UID or User ID. The range of UID values varies amongst different systems; atthe very least, a UID represents a 15-bit integer, ranging between 0 and

The UID value references users in the /etc/passwd file. Shadow password files and Network InformationService also refer to numeric UIDs. The user identifier has become a necessary component of Unix filesystems and processes.

* In POSIX-compliant environments the command-line command id gives the user's user identifier number aswell as more information on the user account like the user name, primary user group and group identifier (GID).

* Files and directories are owned by a user. The owner determines the file's owner class. Distinct permissionsapply to the owner.Files and directories are assigned a group, which define the file's group class. Distinct permissions apply tomembers of the file's group members. The owner may be a member of the file's group. Users who are not theowner, nor a member of the group, comprise a file's others class. Distinct permissions apply to others.The effective permissions are determined based on the user's class. For example, the user who is the owner ofthe file will have the permissions given to the owner class regardless of the permissions assigned to the groupclass or others class.

QUESTION 14Executing this command will have what effect?

Options wafl.default_security_style ntfs

A. It will set the security style of all files to be ntfs.B. It will change the security style of all qtrees to be ntfs.C. It will change the security style of all existing volumes to be ntfs.D. It will set the security style of all newly created volumes to ntfs.



wafl.default_security_styleSpecifies the default security style assigned to a new volume. All qtrees created on the volume get this astheirsecurity style. Legal values for this option are `unix', `ntfs', or `mixed'. The default value for this option is`unix',unless the node is an NTFS-only node, in which case the default is `ntfs'. Note: if cifs setup is run aftersetting wafl.default_security_style, the filer will become an NTFS security stylefiler.

QUESTION 15Which two statements apply to an entry in the /etc/exports file regarding exporting directories/qtrees andvolumes? (Choose two.)

A. Each volume must be exported separately.B. Exports are accessible only to hosts with names.C. User names used in an export must be resolvable.D. Exports can access multiple paths on the same volume.


Explanation/Reference:Explanation:https://library.netapp.com/ecmdocs/ECMP1196890/html/man5/na_exports.5.html

IP addresses and wildcards can be used when specifying host targets in exports. User names are not validexports options, save for the anon option which utilizes a local system UID or username (i.e. no user namemapping or resolution is performed.) The highest level in the filesystem that can be specified for an export isthe volume level. Implicitly this meansthat each volume must be exported separately. An export providesaccess to paths below the export, implying that multiple paths on the same volume can beexported from anexport.

QUESTION 16To automatically export volumes and directories on storage system reboot, include them in the /etc/exports file.

A. TrueB. False


Explanation/Reference:Explanation:https://library.netapp.com/ecmdocs/ECMP1196890/html/man5/na_exports.5.html

The /etc/exports file contains a list of export entries for all file system paths that Data ONTAPexportsautomatically when NFS starts up.

QUESTION 28What are three true statements about physical reallocation of data added in ONTAP 7.3? (Choose three.)

A. Use reallocate -p pathname to run the physical reallocate.B. Use aggr reallocate -p pathname to run the physical reallocate.C. Reinitialize any SnapMirror relationship for the new physical geometry.D. Volume Snapshots do not need to be deleted for the reallocate to run effectively.E. Dont run it on files, volumes, and LUNs that are in an aggregate created by a version of ONTAP earlier than

7.2.

Correct Answer: ADESection: (none)Explanation

Explanation/Reference:Explanation:https://library.netapp.com/ecmdocs/ECMP1196979/html/man1/na_reallocate.1.html

The -p option requests that reallocation of user data take place on the physical blocks in the aggregate, butthelogical block locations within a flexible volume are preserved. Aggregate reallocation is not supported onaggregates created prior to Data ONTAP 7.2. Using the -p option may reduce the extra storage requirements ina flexible volume when reallocation is run ona volume with snapshots. It may also reduce the amount of datathat needs to be transmitted by SnapMirror onits next update after reallocation is performed on a SnapMirrorsource volume.

QUESTION 47Which two statements apply to the fs_size_fixed volume option? (Choose two.)

A. The default setting is on.B. This option is automatically set to be on when a volume becomes a SnapMirrored volume.C. This option turns to off after the snapmirror break command is issued for the relationship.D. This option causes the SnapMirror destination volume to remain the same size and not grow or shrink when

a SnapMirrored volume relationship is broken.


Explanation/Reference:Explanation:This option causes the file system to remain the same size and not grow or shrink when a SnapMirroredvolumerelationship is broken, or when a vol add is performed on it. This option is automatically set to be onwhen avolume becomes a SnapMirrored volume. It will remain on after the snapmirror break command isissued for thevolume. This allows a volume to be SnapMirrored back to the source without needing to adddisks to the sourcevolume. If the volume size is larger than the file system size, turning off this option will forcethe file system togrow to the size of the volume. The default setting is off.http://wafl.co.uk/vol-2/#sthash.DbEHR4YS.dpuf

QUESTION 48Which three statements apply to the SnapMirror visibility_interval argument? (Choose three.)

A. The default interval value is five minutes.B. The smallest interval value supported is 30 seconds.C. This variable controls the view of the data on the destination system.D. By setting a value, you specify the amount of time before an automatic snapshot is created on the source

volume that is synchronously mirrored.


Explanation/Reference:Explanation:http://www.netapp.com/us/media/tr-3326.pdf

http://backdrift.org/man/netapp/man5/na_snapmirror.conf.5.html http://hd.kvsconsulting.us/netappdoc/733docs/html/ontap/onlinebk/GUID-47724B21-7C7E-4AC9- A497-9505B42C27AF.html

With SnapMirror Sync and SnapMirror Semi-Sync, changes to the source volume do not show upimmediatelyon the destination volume, even though the changes have been replicated. The changesare first shown afterthe source system creates an automatic Snapshot copy of the source volume.Snapshot copies created on the source volume are immediately propagated to the destination volume.Theautomatic Snapshot copies are created every three minutes by default.

To change the interval for automatic Snapshot copies, change the visibility_interval in the snapmirror.conf file;however, performance can degrade if set to a smaller interval because frequentSnapshot copies cause additional processing such as cache consistency checking on the destination system.

There is also a disadvantage in setting this to a large value. When the connection between the systems hasanoutage and SnapMirror goes into asynchronous mode, SnapMirror uses the last common Snapshot copytotransition into synchronous mode. This means that all data from the last valid common Snapshot copy willneedto be replicated from the source to the destination storage system. If the visibility_interval is set to alargevalue, a large amount of data might have to be transferred and itmight take longer time for SnapMirrortotransition into synchronous mode. For these reasons, keep the default value of three minutes.

visibility_intervalThe value for this argument is a number optionally followed by the suffixes: s (seconds), m (minutes) or h(hours). If a suffix is not specified, value is interpreted as seconds. This argument controls the amount oftimebefore an automatic snapshot is created on the source volume that is synchronously mirrored. The value isthenumber of seconds between automatically created snapshots. The default value is 3 minutes. A smallnumberhere can negatively affect the performance of the mirror. This argument is ignored for asynchronousmirrors.


visibility_interval={xs | xm | xh}Determines the amount of time before an automatic Snapshot copy is created on the source volume thatisbeing replicated using synchronous or semi-synchronous SnapMirror. When replicating synchronously orsemisynchronously,using SnapMirror, changes to the source volume do not show immediately on thedestinationvolume, even though the changes have been replicated. The changes are shown only after thesource systemtakes an automatic Snapshot copy of the source volume. This event occurs every three minutesby default.

You can change the interval for automatic Snapshot copies, but performance can degrade if you setsmallerintervals because Snapshot copies are taken more often. The smallest interval you can set is 30seconds.Note: The s, m, and h suffixes specify seconds, minutes, and hours, respectively.

QUESTION 49SnapMirror will automatically try to restart a transfer after ___________.

QUESTION 21For aggregates or traditional volume SyncMirror to work correctly, the configuration of each plex should beidentical with regard to ____________.

A. NVRAMB. Mirrored Snapshot copiesC. RAID groups and disk sizesD. NDMP and Snapshot copies


Explanation/Reference:Explanation:SyncMirror is essentially a RAID-1 mirror; hence the name. The best practice is to mirror storage ofequalperformance; i.e. identical RAID groups and disk sizes (number of spindles, IOPS). If you were to mirrortwostorage devices of different performance, the slower device would be the limiting factor.

QUESTION 22What happens when two aggregates are rejoined?

A. It is not possible to rejoin aggregates.B. Data ONTAP will always retain data from the newest aggregate.C. Both aggregates revert to the last common snapshot before the split.D. You will have a large new aggregate containing all volumes from both aggregates.E. One of the aggregates will be overwritten and you will lose any data changed on it after the split.

Correct Answer: ESection: (none)

Explanation

Explanation/Reference:Explanation:When you rejoin split aggregates, Data ONTAP mirrors the data from one aggregate to the other anddestroysdata that existed on that aggregate before the rejoin.

QUESTION 24A mirrored volume has a failed disk, but there are no available spares in the pool from which the degraded plexwas built. Data ONTAP will __________.

A. halt all operations to volumes in that poolB. choose spare disks to reconstruct from the opposite poolC. warn you that there are no available spares from the proper poolD. "halt" after 24 hours if spare disks are not added to the proper pool


Explanation/Reference:Explanation:Both `warn you that there are no available spares from the proper pool' and `halt after 24 hours if spare diskarenot added to the proper pool' are correct answers. However, since Data ONTAP alerts you first, 'warn youthatthere are no available spares' is the best answer. https://library.netapp.com/ecm/ecm_download_file/ECMP1196912

QUESTION 25The required hardware to add SyncMirror to an existing system would be ____________.

A. disk shelves and cluster interconnectB. disk shelves and termination switchesC. disk shelves, Ethernet adapters, and cablingD. disk shelves, Fibre Channel adapters, and cabling

Correct Answer: D



QUESTION 26Which two are true when creating a SyncMirror volume? (Choose two.)

A. The disks selected for Plex 0 and Plex 1 must come from the same disk shelf.B. The disks selected for Plex 0 and Plex 1 must come from the same disk pools.C. The number of disks added must be an even number and equally divided between the two plexes.D. The disks are selected first on the basis of equivalent bytes per sector (bps) size, then on the basis of the

size of the disk. If there is no equivalent-sized disk, Data ONTAP takes a larger capacity disk and right-sizesit.


Explanation/Reference:Explanation:The rules for the selection of disks or array LUNs, for using as mirrored aggregates, are as follows:Disks or array LUNs selected for each plex must be in different pools. The same number of disks or arrayLUNs must be in both the plexes. Disks are selected first on the basis of equivalent bytes per sector (bps) size,then on the basis of the size ofthe disk.If there is no equivalent-sized disk, Data ONTAP uses a larger-capacity disk, and limits the size to makeitidentically sized.Data ONTAP names the plexes of the mirrored aggregate.

QUESTION 27After issuing the aggr split aggr0/plex0 aggrNew command ____________.

A. there is a new plex called aggrNewB. there are two new plexes, plex0 and plexNewC. there is a new mirrored aggregate called aggrNewD. there are two unmirrored aggregates, aggr0 and aggrNewE. flexible volumes are evenly split between aggr0 and aggrNew

Network Appliance NS0-155 Exam


Explanation/Reference:Explanation:https://library.netapp.com/ecmdocs/ECMP1196890/html/man1/na_aggr.1.html aggr split aggrname/plexnamenew_aggrnameRemoves plexname from a mirrored aggregate and creates a new unmirrored aggregate namednew_aggrname that contains the plex. The original mirrored aggregate becomes unmirrored. The plex to besplitfrom the original aggregate must be functional (not partial), but it could be inactive, resyncing, or out-ofdate.

Aggr split can therefore be used to gain access to a plex that is not up to date with respect to its partnerplex, if its partner plex is currently failed.

If the aggregate in which plexname resides is embedded in a traditional volume, aggr split behaves identicallytovol split. The new aggregate is embedded in a new traditional volume of the same name.The aggregate in which plexname resides must contain exactly one flexible volume, aggr split will bydefaultrename the flexible volume image in the split-off plex to be the same as the new aggregate.If the original aggregate is restricted at the time of the split, the resulting aggregate will also be restricted. Iftherestricted aggregate is hosting flexible volumes, they are not renamed at the time of the split. Flexiblevolumeswill be renamed later, when the name conflict is detected while bringing an aggregate online. Flexiblevolumesin the aggregate that is brought online first keep their names. That aggregate can be either theoriginalaggregate, or the aggregate resulting from the split. When the other aggregate is brought online later,flexiblevolumes in that aggregate will be renamed.

If the plex of an aggregate embedded within a traditional volume is offline at the time of the split, theresultingaggregate will be offline. When splitting a plex from an aggregate that hosts flexible volumes, if thatplex isoffline, but the aggregate is online, the resulting aggregate will come online, and its flexible volumes willberenamed. It is not allowed to split a plex from an offline aggregate. A split mirror can be joined back togethervia the -v option to aggr mirror.

QUESTION 28Normally, before you split a SyncMirror volume, you ensure that both plexes are _______ and _______.

A. offline, quiescedB. online, consistentC. online, normalD. restricted, offline


Explanation/Reference:Explanation:Ensure that both plexes of the mirrored aggregate you are splitting are online and operational.

QUESTION 29You can avoid data corruption when you issue the cf forcetakeover -d command if the remote node is________.

A. in a giveback modeB. fenced off manually

C. powered on and accessibleD. powered off and inaccessible



QUESTION 30You have connected all cables and disk shelves in a fabric-attached MetroCluster. Which command wouldverify that disks are connected and have dual paths?

A. disk showB. sysconfig -pC. vol status -rD. storage show disk -p


Explanation/Reference:Explanation:The operator must ensure that the partner filer does not become operational at any time while a filer is inatakeover mode initiated by the use of this command http://backdrift.org/man/netapp/man1/na_cf.1.html

QUESTION 31When using MetroCluster in a forced takeover mode, identify two methods for restricting access to the disastersite node. (Choose two.)

A. Use manual fencing.B. Use the cf giveback -f command.C. Use the cf forcetakeover -d command.D. Turn off power to the disaster site node.E. Isolate the failed node from the surviving node.



QUESTION 32In a fabric-attached MetroCluster, a "site failure" is described as a __________.

A. failure of the Inter-Switch-Links (ISL)B. failure of the interconnect cableC. complete failure of the primary controller and disk shelvesD. malfunction of the Fibre Channel adapter on the cluster node

Correct Answer: C


Explanation/Reference:Explanation:http://argoat.net/Blog/?p=1466

QUESTION 33Which two statements are true of the cf forcetakeover -d command? (Choose two.)

A. Mirrored volumes are implicitly split.B. Partner mailboxes must be available.C. The failed cluster node is powered off automatically.D. The surviving cluster node takes over the functions of the failed partner.



It is important to remember that this is the case only when a complete site is lost. In the case of afailedcontroller at one of the sites, a normal cluster failover occurs. Due to the operation of SyncMirror, there isalsoadded protection from multidrive or complete shelf failures. When a storage controller fails in an active-activeconfiguration, the partner detects the failure and automatically (if enabled) performs a takeover of thedataservingresponsibilities from the failed controller. Part of this process relies on the surviving controllerbeingable to read information from the disks on the failed controller. If this quorum of disks is not available,thenautomatic takeover won't be performed. In a MetroCluster configuration, manually executing a singlecommandwill allow a takeover to occur in spite of the lack of a quorum of disks. This "forced takeover" processbreaksthe mirrored relationships in order to bring the failed controller's volumes on line.

forcetakeover -d is very dangerous. Not only can it cause data corruption, if not used carefully, it can alsolead toa situation where both the node and its partner are operational (split brain). As such, it should only beused as ameans of last resort when the takeover and forcetakeover commands are unsuccessful inachieving a takeover.The operator must ensure that the partner node does not become operational at any timewhile a node is in atakeover mode initiated by the use of this command. In conjunction with RAID mirroring, itcan allow recoveryfrom a disaster when the two nodes in the HA pair are located at two distant sites.

QUESTION 34Protection Manager is an optional component of the Operations Manager that can be licensed and accessedfrom the NetApp Management Console (NMC).

QUESTION 36Which are three valid data protection solutions? (Choose three.)

A. SnapVault toVolume SnapMirrorB. SnapVault toVolume SnapMirror to SnapVaultC. SnapVault toVolume SnapMirror toVolume SnapMirrorD. Volume SnapMirror to SnapVault


Explanation/Reference:Explanation:http://www.redbooks.ibm.com/redpapers/pdfs/redp4268.pdf

When you are using SnapVault in combination with Volume SnapMirror, it is important to understandtheirrelationship with Snapshot. You cannot utilize SnapVault to protect a Volume SnapMirror destination,becauseSnapVault and SnapMirror both use the same Snapshot copies; they cannot run simultaneously.Schedulesmust be managed to accommodate the interlock that keeps SnapVault and SnapMirror fromstepping on eachother.

QUESTION 37Protection Manager has policies that allow for tape-based protection as well as disk-based protection.

Explanation/Reference:Explanation:Open Systems Snap Vault runs on servers, so the objects that can be selected for backup will be host-based.Qtrees are objects on the storage system.

QUESTION 39XML-files in /etc/stats/preset are used together with the sysstat command to customize the output.

A. TrueB. False


Explanation/Reference:Explanation:https://library.netapp.com/ecmdocs/ECMP1196890/html/man1/na_stats.1.html http://backdrift.org/man/netapp/man5/na_stats_preset.5.html

Data ONTAP provides some XML files that output a predetermined set of statistics that you can usewithouthaving to construct a script or type in a complicated command on the command line.

The preset files are located in the /etc/stats/preset directory. To use a preset file, you add -p filename toyourstats show or stats stop command line. You can also add counters on the

command line. If any optionsyou specify on the command line conflict with the preset file, your command lineoptions take precedence.

You can also create your own preset files.

QUESTION 40When migrating from Data ONTAP 7G to Data ONTAP 8.0 7-mode, existing non-traditional aggregates aredesignated as ________.

A. 16-bitB. 32-bitC. 64-bitD. ForeignE. Unknown


Explanation/Reference:Explanation:Aggregates are never converted as part of an upgrade. An upgrade will not touch your data!

QUESTION 41To create a 64-bit aggregate, which optional switch/flag/parameter/option to the aggr create command must beincluded?

A. b 64B. B 64C. l 64D. L 64E. No optional switch/flag/parameter/option is needed because 64-bit aggregates are the default



The command to create a 64-bit aggregate is the same aggr create command that is present in DataONTAP7G for aggregate creation. The aggr create command has a new flag, -B, to specify

the type of aggregate tocreate. It takes a value of either 32 or 64 and creates the respective type of aggregate.Therefore the aggrcreate command with -B 64 creates a 64-bit aggregate. The aggr create command withoutthe -B flag bydefault creates a 32-bit aggregate.

Here are some commands for creating different aggregate types in Data ONTAP 8.0:Creating a 64-bit aggregate:aggr create aggr_64 -B 64 5Creating a 32-bit aggregate using B flag:aggr create aggr_32 -B 32 5Creating a 32-bit aggregate without using B flag:aggr create default_aggr_32 5Note: the man pages do not include this option in later versions of DOT because 64-bit is now the default.

QUESTION 42After upgrading to DOT 8.07-mode, you can convert existing 32-bit aggregates into 64-bit aggregates.

A. TrueB. False


Explanation/Reference:Explanation:http://www.ntapgeek.com/2011/12/how-in-place-expansion-works.html

To upgrade an aggregate in-place, the only available method is to add disks to expand the aggregate to>16TB.There is an obscure method using diag mode but that is not supported or mentioned in the exam content.Theanswer is always add disks to grow past 16TB, or migrate.

QUESTION 43With 64-bit aggregates, the number of FlexVols that can be created on a storage controller is ____.

A. 500B. 1000C. 6400D. 64000


Explanation/Reference:Explanation:http://www.netapp.com/us/products/storage-systems/fas3200/fas3200-tech-specs.aspx

There is no easily remembered reason why its 500. Some people like to remember that there is oneotherquestionon the exam that requires you to remember an arbitrary number and the answer is also 500(distanceof a fiber interconnect at 2Gbps).

QUESTION 44The largest volume that can be created on a 64-bit aggregate is ___.

A. 10 TBB. 16 TBC. 64 TBD. Equal to size of the aggregate



Trick question.... Depends on the array and the maximum shelves and disks and aggregate size, which

canchange over time. But a volume can never be greater than the aggregate - save for a new feature in 8.2calledInfinite Volume that is not covered by this exam.

QUESTION 49NetApp recommends that Fibre Channel switches that have both disk and tape connected to them should haveseparate zones created for each.

A. TrueB. False


Explanation/Reference:Explanation:http://www.brocade.com/downloads/documents/white_papers/Zoning_Best_Practices_WP-00.pdf

Separating the disk and tape devices into separate zones prevents disk RSCNs from impacting tapedevices,which tend to be more sensitive to RSCNs. Best practice is to zone each initiator WWPN to each targetWWPN individually.

QUESTION 51The quota resize command only affects existing /etc/quotas file target entries, not new quota entries.

A. TrueB. False


Explanation/Reference:Explanation:http://backdrift.org/man/netapp/man1/na_quota.1.html

quota resize volumeAdjusts currently active quotas in the specified volume to reflect changes in the /etc/quotas file. Forinstance, ifyou edit an entry in /etc/quotas to increase a user's quota, quota resize will cause

thechange to take effect. The volume name may be omitted if the system has only one volume. quota resizecanbe used only when quotas are already on. Because it does not rescan the file system to compute usage,quotaresize is faster than turning quotas off and then on again. quota resize will apply all updatedentries in /etc/quotas; however, it will generally ignore newly added entries. A newly added entry will onlytake effect if thecorresponding user or group has an active quota as a result of updating a file subject todefault quotas.

QUESTION 52In Data ONTAP, the root user is exempt from these two quotas: _______. (Choose two.)

QUESTION 55Which iSCSI security method encrypts data between the initiator and the target?

A. IPSecB. CHAPC. LUN maskingD. Header and Data Digests


Explanation/Reference:Explanation:IPSec is an encryption transport that can be used to secure any IP traffic including iSCSI.

QUESTION 56You receive an error message from an iSCSI host stating that there is an authentication error.Which command would troubleshoot the failure?

A. iscsi security showB. iscsi security generateC. iscsi show authenticationD. iscsi security authentication


Explanation/Reference:Explanation:https://library.netapp.com/ecmdocs/ECMP1196890/html/man1/na_iscsi.1.html

iscsi security showDisplay the default authentication and all the initiator specific authentication information. Hint: Remember thatthe iscsi command is mostly structured "iscsi noun verb", unlike the fcp command whichis structure "fcp verbnoun". Example: iscsi initiator show, fcp show initiator.

QUESTION 57Which three steps should be taken when troubleshooting a "stale nfs file handle" response to a NFS mountrequest on a Solaris system? (Choose three)

A. check the client's fstabB. check the /etc/sd.conf file on the clientC. check show mount -e to the storage system from the clientD. check for connectivity to the storage system from the clientE. check the output of the exportfs command on the storage system

Correct Answer: ADESection: (none)Explanation

Explanation/Reference:Explanation:The fstab file reflects the defined filesystem mount paths (including NFS mounts). Always check networkconnectivity when a problem arises with a network service. The exportfs command will display the activeexports on the storage system.

QUESTION 58Which three configurations would increase data transfer rates in a volume SnapMirror environment fortraditional volumes?

A. The destination volumes are flexible volumes.B. The destination and source contain disks of the same size.C. The destination and the source contain RAID groups of the same size.D. The destination and source contain the same number of raid groups.E. The destination and source storage systems are no father than 30 meters apart.


Explanation/Reference:Explanation:By aligning the performance of the source and destination, optimal data transfer (aka replication) rates canbeattained. Flexvols don't matter, and there is no measurable difference between the performance of anetworkover a 30m or 3m cable.

QUESTION 59Identify the two commands that could be entered on a system with a SnapMirror source. (Choose two)

A. snapmirror updateB. snapmirror statusC. snapmirror initializeD. options snapmirror.access all



http://www.uow.edu.au/~blane/netapp/ontap/cmdref/man1/na_options.1.htm update [ -S source ] [ -k kilobytes ][ -s src_snap ] [ -c create_dest_snap ] [ -w ] destination For asynchronous mirrors, an update is immediatelystarted from the source to the destination to update themirror with the contents of the source.

For synchronous mirrors, a snapshot is created on the source volume which becomes visible to clients ofthedestination volume.

The update command must be issued on the destination node.status [ -l | -t | -q ] [ volume | qtree ... ]Reports status of all the SnapMirror relationships with a source and/or destination on this node. Thiscommandalso reports whether SnapMirror is on or off. If any volume or qtree arguments are given to thecommand, onlythe SnapMirror relationships with a matching source or destination will be reported. If theargument is invalid,there won't be any status in the output.initialize [ -S source ] [ -k kilobytes ] [ -s src_snap ] [ -c create_dest_snap ] [ -w ] destinationStarts an initial transfer over the network. An initial transfer is requiredbefore update transfers can take place.

The initialize command must be issued on the destination node. If the destination is a volume, it

must berestricted (see na_vol(1) for information on how to examine and restrict volumes). If the destination is aqtree, itmust not already exist (see na_qtree(1) for information on how to list qtrees). If a qtree already exists, itmustbe renamed or removed (using an NFS or CIFS client), or snapmirror initialize to that qtree will notwork.snapmirror.access

This option determines which SnapMirror destination filers may initiate transfers, and over whichnetworkinterfaces. When set to "legacy", SnapMirror uses the older snapmirror.allow to determine access. Theoptionvalue is a string containing an expression which provides the access filter. An example of theoptionscommand for snapmirror.access is options snapmirror.access host=toaster,fridge. The default valueis"legacy". See na_snapmirror(1) , na_snapmirror.allow(5) and na_protocolaccess(8) for more details.

The snapmirror.allow file exists on the source filer used for SnapMirror.

QUESTION 60Which OSSV tool would you use to perform an OSSV unattended installation?

A. msipackageB. svunattendossvC. svconfigpackagerD. unattendpackager


Explanation/Reference:Explanation:The reference for thisquestionis an old version of a TR. It is likely that thisquestionwill be removed fromtheNSO-155 exam.The svconfigpackager is a binary in the OSSV client which can be used to create an unattendedinstallationpackage using an answer file.

QUESTION 61Which command creates a new SyncMirror aggregate, letting Data ONTAP select the disk drives?

A. aggr create aggrX -d 12

B. aggr create aggrX -m 12C. aggr mirror aggrX -m 12D. aggr mirror aggrX -n 12


Explanation/Reference:Explanation:https://library.netapp.com/ecmdocs/ECMP1196890/html/man1/na_aggr.1.html The following commands areavailable in the aggr suite:

If you use the -d disk1 [ disk2 ... ] argument, the node creates the aggregate with the specified sparedisksdisk1, disk2, and so on. You can specify a space-separated list of disk names. Two separate lists mustbespecified if the new aggregate is mirrored. In the case that the new aggregate is mirrored, the indicateddisksmust result in an equal number of disks on each new plex.

The disks in a plex are not permitted to span spare pools. This behavior can be overridden with the -f option.

The same option can also be used to force using disks that do not have matching rotational speed. Thefoptionhas effect only when used with the -d option specifying disks to use.

The -m option can be used to specify that the new aggregate be mirrored (have two plexes) upon creation.Ifthis option is given, then the indicated disks will be split across the two plexes. By default, the newaggregatewill not be mirrored.

aggr mirror aggrnameThe -n option can be used to display the command that the system will execute without actually makinganychanges. This is useful for displaying the automatically selected disks, for example.

QUESTION 62Which SyncMirror command mirrors an existing unmirrored aggregate where Data ONTAP selects the diskdrive?

A. aggr mirror aggrYB. aggr mirror aggrY -mC. aggr mirror aggrT -d 12@144D. aggr mirror aggrY -m 12@144



Explanation:https://library.netapp.com/ecmdocs/ECMP1196890/html/man1/na_aggr.1.html

aggr mirror aggrname[ -f ][ -n ][ -v victim_aggrname ][ -d disk1 [ disk2 ... ] ]Turns an unmirrored aggregate into a mirrored aggregate by adding a plex to it. The plex is eithernewlyformedfrom disks chosen from a spare pool, or, if the -v option is specified, is taken from anotherexistingunmirrored aggregate. Aggregate aggrname must currently be unmirrored. Use aggr create to make anew,mirrored aggregate from scratch.

Disks may be specified explicitly using -d in the same way as with the aggr create and aggr add commands.

The number of disks indicated must match the number present on the existing aggregate. The disksspecifiedare not permitted to span disk pools. This behavior can be overridden with the -f option. The -f option,incombination with -d, can also be used to force using disks that have a rotational speed that does notmatchthat of the majority of existing disks in the aggregate.

If disks are not specified explicitly, then disks are automatically selected to match those in theaggregate'sexisting plex.

The -v option can be used to join victim_aggrname back into aggrname to form a mirrored aggregate. Theresultis a mirrored aggregate named aggrname which is otherwise identical to aggrname before the operation.

Victim_aggrname is effectively destroyed. Victim_aggrname must have been previously mirrored withaggrname, and then separated via the aggr split command. Victim_aggrname must be offline. Combinedwiththe -v option, the -f option can be used to join aggrname and victim_aggrname without prompting the user.

The -n option can be used to display the command that the system will execute without actually makinganychanges. This is useful for displaying the automatically selected disks, for example.


QUESTION 63When troubleshooting a double disk failure with SyncMirror, you decide to remove and destroy a plex from amirrored aggregate. What steps remove a plex from a mirrored aggregate?

A. Take the aggregate offline and use the aggr destroy commandB. Take the aggregate offline and use the destroy -f commandC. Ensure the plex is online and use the aggr destroy plexname command.D. Ensure the plex is offline and use the aggr destroy plexname command.


Explanation/Reference:Explanation:https://library.netapp.com/ecmdocs/ECMP1196890/html/man1/na_aggr.1.html

aggr destroy { aggrname | plexname } [ -f ]Destroys the aggregate named aggrname, or the plex named plexname. Note that if the specified aggregateistied to a traditional volume, then the traditional volume itself is destroyed as well. If an aggregate is specified,all plexes in the aggregate are destroyed. The named aggregate must also notcontain any flexible volumes,regardless of their mount state (online, restricted, or offline). If a plex is specified,the plex is destroyed, leavingan unmirrored aggregate or traditional volume containing the remaining plex.

Before destroying the aggregate, traditional volume or plex, the user is prompted to confirm the operation. The-fflag can be used to destroy an aggregate, traditional volume or plex without prompting the user.

The disks originally in the destroyed object become spare disks. Only offline aggregates, traditionalvolumesand plexes can be destroyed.

QUESTION 64When replicating data between 32-bit and 64-bit aggregates, which two are allowed? (Choose two)

A. NDMPcopyB. QSMC. vol copyD. VSM

Correct Answer: ABSection: (none)Explanation


http://wafl.co.uk/ndmpcopy/Because volume SnapMirror works at the block level, the source and destination must both be FlexVolvolumesin the same aggregate type. The source and destination of a volume SnapMirror relationship musteither both beFlexVol volumes in 32-bit aggregates or both be FlexVol volumes in 64-bit aggregates.

Therefore you cannot create a volume SnapMirror relationship from a FlexVol volume in a 32-bit aggregate toaFlexVol volume in a 64-bit aggregate or vice versa.


QUESTION 65What types of migration are supported from 32-bit to 64-bit?

A. migration of qtrees via QSMB. migration of volumes via ndmpcopyC. migration of volumes via SnapMirrorD. Both A & BE. Both B & CF. Both A & C


Explanation/Reference:Explanation:Volume SnapMirror operates at the physical block level. It replicates the contents of an entire volume,includingall Snapshot copies, plus all volume attributes verbatim from a source (primary) volume to a target(secondary)volume. Implicitly, the destination volume will be the same as the source volume. Since C isincorrect, A & Bmust be correct.

Qtree snapmirror operates at the logical level, so it is unimportant that the destination system has adifferentvolume configuration.

ndmpcopy is similarly operating with data already read from the volume and so the destination volume typeisnot a consideration.

QUESTION 66How do you migrate LUNs under volumes from 32-bit to 64-bit?

A. lrepB. ndmpcopyC. rsyncD. snapvault


Explanation/Reference:Explanation:http://wafl.co.uk/ndmpcopy/Think of ndmpcopy as a sort of ftp for SAN. You can use it to copy files from one volume to

another. Becausethe file is read from one volume and written to another, the constraints of volume types arenot an issue.

QUESTION 67Which three FAS deduplication features exist in ONTAP 8.0 7-Mode?

A. The deduplication fingerprint and change logs were moved to the root volume /etc/dedup directory.B. After breaking the deduplication volume destination mirror, the deduplication (a-sis) process

continuesuninterrupted.C. Qtree SnapMirror is supported on the destination for deduplication by enabling on the source, destination,

orboth systems.D. The fingerprint database and the change logs that the deduplication process uses are located outside

thevolume, in the aggregate.E. The deduplication schedule is not tied to a Qtree SnapMirror update, and can be configured just like

thededuplication schedule for any volume.

Correct Answer: CDESection: (none)Explanation

Explanation/Reference:Explanation: Section: Data ProtectionNetApp also recommends that if deduplication is used on the source volume, then it should also be used onthedestination volume. However, you are not restricted using deduplication on the source volume only.The deduplication schedule is not tied to the qtree SnapMirror update. In other words, the deduplicationprocessdoes not automatically start at the completion of the qtree SnapMirror transfer.The fingerprint database and the change log files that are used in the deduplication process are locatedoutsideof the volume in the aggregate and are therefore not captured in Snapshot copies http://www.netapp.com/us/media/tr-3505.pdf

QUESTION 68To manage SnapVault relationships with an NDMP management application, you must specify a:

A. directory pathB. volume and qtreeC. SnapVault licenseD. username and password


Explanation/Reference:Explanation:Add a new backup user to the Backup Operators useradmin group list. Enter the following command:useradmin user add backupuser -g "Backup Operators"Generate an NDMP password for the new user. Enter the following command:ndmpd password backupuserThe NDMP password is used to authenticate the NetBackup media server to the storage system. Thispasswordis required for setup on the NetBackup management station. https://library.netapp.com/ecmdocs/ECMM1278284/html/onlinebk/5snapv37.htm

QUESTION 69For OSSV sources, the qtree is the basic unit of SnapVault backups.

A. TrueB. False


Explanation/Reference:Explanation:https://library.netapp.com/ecmdocs/ECMP1196991/html/GUID-06C70D3B-9A06-4D20-B140-EB147B941BDA.html

The data structures that are backed up and restored through SnapVault depend on the primary system.On systems running Data ONTAP, the qtree is the basic unit of SnapVault backup and restore. SnapVaultbacks up specified qtrees on the primary system to associated qtrees on the SnapVaultsecondary system. Ifnecessary, data is restored from the secondary qtrees back to their associated primaryqtrees.On open systems storage platforms, the directory is the basic unit of SnapVault backup. SnapVaultbacks upspecified directories from the native system to specified qtrees in the SnapVault secondary system.If necessary SnapVault can restore an entire directory or a specified file to the open systems platform.The destination system uses a slightly more disk space and directories than the source system.
