Chapter 6 With 100% Accurate Answers

1. Which command is used to view the RIP routing protocol settings and

configuration?

show versionshow ip route

show interface**show ip protocols

2. Refer to the exhibit. What is the maximum number of RIP routers that could

separate HostA and HostB and still leave the hosts with connectivity to each other?

14

15**16

17

3. In which situation would a company register for its own autonomous system

number (ASN)?

when the company's ISP adds connection points to the Internetwhen additional routers are added to the corporate internetwork

when more than one interior routing protocol is used**when the company uses two or more ISPs

4. Consider this routing table entry

R 172.16.1.0/24 [120/1] via 200.1.1.1 00:00:27 Serial0/1

What type of route is this?

a static routea default route

**a RIP routean OSPF route

an EIGRP routea directly-connected route

5. What is the difference between interior and exterior routing protocols?

Exterior routing protocols are only used by large ISPs. Interior routing protocols are used

by small ISPs.

Interior routing protocols are used to route on the Internet. Exterior routing protocols areused inside organizations.

Exterior routing protocols are used to administer a single autonomous system. Interior

routing protocols are used to administer several domains.**Interior routing protocols are used to communicate within a single autonomous system.Exterior routing protocols are used to communicate between multiple autonomous

systems.

6. What information is included in RIPv2 routing updates that is not included in

RIPv1 updates?

metric**subnet mask

area identificationhop count

autonomous system number

7. Which routing protocol is used to exchange data between two different ISPs?

**BGP

EIGRPOSPF

RIP v2

8. Refer to the exhibit. Which configuration command or commands contributed to

the output that is shown?

routerA(config-router)# no version 2routerA(config)# interface fa0/0

routerA(config-if)# ip address 172.19.0.0 255.255.0.0**routerA(config-router)# network 192.168.3.0

routerA(config)# no ip default-gateway

9. Refer to the exhibit. If all routers are running RIP and network 10.0.0.0 goes

down, when will R3 learn that the network is no longer available?

in 30 secondsin 60 seconds

in 90 seconds**Immediately

10. What statement is true regarding an AS number?

AS numbers are controlled and registered for Internet use.

Interior routing protocols require registered AS numbers.ISPs require all customers to have registered AS numbers.All routers at an ISP must be assigned the same AS number.

11. What is the purpose of the network command used when configuring RIP?

to specify whether RIPv1 or RIPv2 will be used as the routing protocolto allow the router to monitor RIP updates that occur on other routers

**to identify which networks on the router will send and receive RIP updatesto configure the IP address on an interface that will use RIP

to identify all of the remote networks that should be reachable from the router

12. Which command would a network administrator use to determine if the routers

in an enterprise have learned about a newly added network?

router# show ip addressrouter# show ip route

**router# show ip networksrouter# show ip interface brief

router# debug ip protocolrouter# debug rip update

13. What is the purpose of a routing protocol?

It is used to build and maintain ARP tables.It provides a method for segmenting and reassembling data packets.

It allows an administrator to devise an addressing scheme for the network.**It allows a router to share information about known networks with other routers.

It provides a procedure for encoding and decoding data into bits for packet forwarding.

14. What device enables an ISP to connect with other ISPs to transfer data?

**border gateway router

DSLAMweb server

interior router

15. Which command will display RIP routing updates as they are sent and received?

show ip route

show ip rip

debug ip ripshow ip protocols**show ip rip database

16. Which part of an IP packet does the router use to make routing decisions?

source IP addresssource MAC address

**destination IP addressdestination MAC address

17. What two types of businesses would benefit from registering as their own

autonomous systems? (Choose two.)

a home business with one ISP connection

**a global business with connections to multiple local ISPs**a medium-sized nationwide business with Internet connectivity through different ISPs

a large enterprise with two connections to the same ISPa small ISP with a single Internet connection through a larger ISP

18. Which command will display RIP activity as it occurs on a router?

debug ip ripshow ip route

show ip interfaceshow ip protocols

debug ip rip config**show ip rip database

19. Why is fast convergence desirable in networks that use dynamic routing

protocols?

**Routers will not allow packets to be forwarded until the network has converged.

Hosts are unable to access their gateway until the network has converged.Routers may make incorrect forwarding decisions until the network has converged.

Routers will not allow configuration changes to be made until the network has converged.

20. Which two statements describe static routes? (Choose two.)

They are created in interface configuration mode.

**They require manual reconfiguration to accommodate network changes.

They automatically become the default gateway of the router.**They are identified in the routing table with the prefix SThey are automatically updated whenever an interface is reconfigured or shutdown.

21. Which two statements or sets of statements describe differences between link-

state and distance vector routing protocols? (Choose two.)

Link-state routing protocols routinely use more bandwidth for updates than do distance

vector routing protocols.Distance vector routing protocols update all routers at one time. Link-state routing

protocols update one router at a time.**Link-state routers only know about directly connected routers. Distance vector routers

know about every router in the network.**Link-state routing protocols update when a change is made. A network using distance

vector routing protocols only updates at a specific interval.Distance vector routing protocols have limited information about the entire network. Link

state routing protocols know about all routers in the network.In case of similar topologies, networks using link-state routing protocols typically

converge more rapidly than do networks using distance vector routing protocols.

22. Which protocol is an exterior routing protocol?

**BGP

EIGRPOSPF

RIP

23. Hosts on two separate subnets cannot communicate. The network administrator

suspects a missing route in one of the routing tables. Which three commands can be

used to help troubleshoot Layer 3 connectivity issues? (Choose three.)

**Ping

show arp**Traceroute

**show ip routeshow interface

show cdp neighbor detail
