The storage I/O path provides virtual machines with access to storage devices. How does it achieve this? Choose one.
A:
Through device emulation
Through paravirtualization
Through guest emulation
Through kernel emulation
In order to ensure that Storage I/O resources are allocated fairly amongst a set of virtual machines, your customer has enabled Storage I/O control. However they are concerned that one virtual machine appears to be using more resources than the other virtual machines and is not respecting the behaviour they anticipated when using SIOC. Which of the following could be a possible cause of the issue? Choose two.
A:
The virtual machine is located on fibre channel storage
The virtual machine has raw device mappings
The datastore is made up of multiple extents
Storage I/ O control is not enabled on the server
Your customer has asked you to confirm the storage location of snapshot delta files for a VM. The VM configuration files ( .vmx, .nvram etc) are located in a folder in the consolidated HRVMs datastore but both its boot and data VMDK disks are stored in a folder in the isolated HRDATA datastore. The customer wants to ensure they have enough free capacity in the datastores to ensure that snapshots can be taken safely but need to know where the various snapshot data files will be stored. Which of the following statements is true? Choose two.
A:
The .vmsd Snapshot metadata and the .vmsn snapshot running state files will be stored in the HRVMs datastore
The .vmsd Snapshot metadata and the .vmsn snapshot running state files will be stored in the HRDATAs datastore
The delta.vmdk snapshot disk files for the boot and data VMDKs will be stored in the HRVMs datastore
The delta.vmdk snapshot disk files for the boot and data VMDKs will be stored in the HRDATA datastore
Which of the following are specific disadvantages of an isolated storage design where each virtual machine is mapped to a single LUN? Choose two.
A:
The design has poor scalability and will quickly reach the upper limit of 256 LUNS and VMFS volumes per ESXi Host
Storage DRS cannot be used to ensure that storage resources are dynamically allocated in response to utilization needs
vSphere HA and vSphere Fault Tolerance cannot be used for virtual machines that use isolated storage.
You will be unable to use RDM disks as the RDM mapping file must be stored on a consolidated VMFS datastore.
vSphere VMFS datastores can be configured using thin provisioned SAN volumes. Virtual Machines can crash if they are stored on a thin provisioned SAN volume that runs out of spare capacity while the VM is attempting to write new data. Which SAN hardware feature allows vSphere 5.1 to address this problem in a more controlled manner? Choose two.
A:
VAAI VM Stun primitive
VASA VM Stun primitive
VAAI VM Shutdown primitive
VASA VM Shutdown primitive
You are allocating storage in a new environment and need to decide how much free capacity you leave unallocated in each datastore once all virtual machines have been provisioned. You know that snapshots will rarely be used in this environment. Choose one.
A:
40-50%
10-20%
20-30%
0-10%
Your customer has a large NAS infrastructure that provides all of the virtual storage capacity for their vSphere 5.1 environment. They have been expanding capacity recently and have reported that they are unable to access one of two new NFS v3 NAS share that they have just added. What is the most likely root cause and what should they do to resolve this issue? Choose one.
A:
vSphere 5.1 supports only 8 NFS Datastores by default, that limit must be increased in order to be able to mount both the new datastores
vSphere 5.1 can only support 8 v3 NFS v3 Datastores concurrently, their new storage must support NFS v4.
Create an extended NFS Datastore using the second NFS v3 mount as a volume extent.
First vSphere 5.1 supports a maximum of 8 NFS Datastores, they should reconfigure the NAS storage to combine the underlying storage on the array.
vSphere 5.1 virtual machines see their storage as SCSI attached disks. These virtual disks can be provisioned in which two of the following ways? Choose two.
A:
As VMDK format files on VMFS or NFS Datastores
As block storage using a Raw Device Mapping (RDM)
As VMDK formatted local or SAN attached SCSI disks first att
As local, SAN attached or NAS VMFS disks first att
What is the maximum number of ESXi hosts that be connected concurrently to a single VMFS-5 volume? Choose one.
A:
8
64
128
256
Your customer uses hardware based thin provisioning on their SAN for VMFS datastores that store Windows virtual machines and is very interested in the new Space Efficient Sparse Disk VMDK format that is supported by vSphere 5.1. The customer wants to test SE Sparse disks for some new Windows Server 2008 VMs in order to compare it with the SAN hardware solution. What pre-requisite for SE Sparse disks in vSphere 5.1 prevents them doing this in their current environment? Choose one.
A:
SE Sparse Disk format can only be used VMware View 5.1 and Horizon View 5.x
SE Sparse Disk format is only compatible with Virtual Machines running Linux
SE Sparse Disk format requires that the VMDKs are stored on NFS Datastores
SE Sparse Disk format is only configurable for Windows Desktop Virtual Machines
When analyzing the capacity planning reports for a new virtualization project the initial storage analysis suggests that you will need approximately 300 x 250 GB VMFS volumes in the customers vSphere 5.1 cluster. This is based on the number of virtual machines and the customers request that each virtual machine be mapped to a single VMFS datastore. What specific problem does this cause and what should you recommend to the customer to resolve it? Choose one.
A:
vSphere 5.1 supports a maximum of 256 VMFS volumes per ESXi host, some virtual machines will have to be provisioned on shared VMFS datastores
vSphere 5.1 supports a maximum of 64 VMFS volumes per ESXi host, most virtual machines will have to be provisioned on shared VMFS datastores
vSphere 5.1 supports a maximum of 64TB of VMFS storage per ESXi host, some VMFS datastores will have to be reduced in size
vSphere 5.1 supports a maximum of 256 VMFS datastores per ESXi host by default, that limit must be increased on each ESXi host
You want to copy a number of ISO files into a vSphere Datastore so they can be used to build virtual machines and templates and want to access the datastore on a client system in order to do this. Which of the following statements is true? Choose one.
A:
You can mount any vSphere Datastore on other systems provided there are no virtual machines running at the time
You can only mount vSphere Datastores on other systems when they are not connected to ESXi hosts
You can mount NFS Datastores on other systems while they are mounted on ESXi hosts
You can only remotely access VMFS Datastores that use iSCSI block storage.
Your customer has an existing multi-protocol SAN that supports both Fibre Channel (FC) and iSCSI storage networks. Their existing vSphere ESXi cluster uses FC for all shared storage but the SAN is configured to provide iSCSI storage to a number of other systems. The customer wants to extend their vSphere cluster but due to the cost of the FC HBAs and switch upgrades that would be required has specified that the new ESXi hosts must be configured to use iSCSI storage. How will this impact the design and features of the new vSphere environment? Choose one.
A:
vSphere cannot access the same storage through different protocols so the new ESXi hosts cannot be configured with iSCSI storage.
vSphere cannot access the same storage through different protocols so the new ESXi hosts will have to be in separate HA clusters
vSphere can access the same storage through different protocols so the new ESXi hosts can be configured with iSCSI storage
vSphere can access the same storage through different protocols provided the ESXi hosts are configured with converged HBAs
You are deciding on the datastores to be used for a storage solution and have to choose whether to allocate isolated or consolidated storage for the virtual machines. You have decided on a consolidated storage design for most virtual machines and need to identify the virtual machines that might be more suitable for isolated storage. Which of the following would be good reasons for specifying isolated storage for a virtual machine? Choose two.
A:
The VM runs a mission critical heavy I/O workload
The VM requires direct access to its storage hardware
The VM will require more than 2TB of virtual storage
The VM does not need to be protected by vSphere HA
During the site survey for a new vSphere 5.1 migration project you find that the customer has a series of application servers that are currently configured with 32 separate physical disks. The customer has said that they wish to retain this underlying structure during the migration rather than consolidate these into a smaller number of disks. How can the virtual machine storage for these VMs be configured to support this? Choose one.
A:
Three virtual SCSI Controllers of any type
Three virtual Paravirtualized SCSI Controllers
First attThree virtual LSI Logic SAS SCSI Controllers
