1 Review Questions The following questions are designed to test your understanding of this chapter s material. For more information on how to get additional questions, please see a. You can find the answers to these questions in Appendix B, Answers to Review Questions. 1. There are three possible routes for a router to reach a destination network. The first route is from OSPF with a metric of 782. The second route is from RIPv2 with a metric of 4. The third is from EIGRP with a composite metric of Which route will be installed by the router in its routing table? A. RIPv2 B. EIGRP C. OSPF D. All three 2. Which EIGRP information is held in RAM and maintained through the use of Hello and update packets? (Choose two.) A. Neighbor table B. STP table C. Topology table D. DUAL table 3. What will be the reported distance to a downstream neighbor router for the network, with the neighbor adding the cost to find the true FD? P /24, 1 successors, FD is via ( /128256), Serial0/0 A. Four hops B C D. EIGRP doesn t use reported distances. 4. Where are EIGRP successor routes stored? A. In the routing table only B. In the neighbor table only C. In the topology table only D. In the routing table and the neighbor table E. In the routing table and the topology table F. In the topology table and the neighbor table

2 5. Which command will display all the EIGRP feasible successor routes known to a router? A. show ip routes * B. show ip eigrp summary C. show ip eigrp topology D. show ip eigrp adjacencies E. show ip eigrp neighbors detail 6. Which of the following commands are used when routing with EIGRP or EIGRPv6? (Choose three.) A. network B. eigrp router-id C. variance D. router eigrp E. maximum-paths 7. Serial0/0 goes down. How will EIGRP send packets to the network? Corp#show ip eigrp topology [output cut] P /24, 2 successors, FD is via ( / ), Serial0/0 via ( / ), Serial0/2 via ( / ), Serial0/1 A. EIGRP will put the network into active mode. B. EIGRP will drop all packets destined for C. EIGRP will just keep sending packets out s0/1. D. EIGRP will use s0/2 as the successor and keep routing to What command do you use to enable EIGRPv6 on an interface? A. router eigrp as B. ip router eigrp as C. router eigrpv6 as D. ipv6 eigrp as

3 9. What command was typed in to have these two paths to network in the routing table? D [90/ ] via , 00:00:20, Serial0/1 [90/ ] via , 00:00:20, Serial0/0 A. maximum-paths 2 B. variance 2 C. variance 3 D. maximum-hops A route to network goes down. How does EIGRP respond in the local routing table? (Choose two.) A. It sends a poison reverse with a maximum hop of 16. B. If there is a feasible successor, that is copied and placed into the routing table. C. If a feasible successor is not found, a query will be sent to all neighbors asking for a path to network D. EIGRP will broadcast out all interfaces that the link to network is down and that it is looking for a feasible successor. 11. You need the IP address of the devices with which the router has established an adjacency. Also, the retransmit interval and the queue counts for the adjacent routers need to be checked. What command will display the required information? A. show ip eigrp adjacency B. show ip eigrp topology C. show ip eigrp interfaces D. show ip eigrp neighbors 12. For some reason, you cannot establish an adjacency relationship on a common Ethernet link between two routers. Looking at the output shown here, what are the causes of the problem?(choose two.) RouterA##show ip protocols Routing Protocol is "eigrp 20" Outgoing update filter list for all interfaces is not set Incoming update filter list for all interfaces is not set Default networks flagged in outgoing updates Default networks accepted from incoming updates EIGRP metric weight K1=1, K2=0, K3=1, K4=0, K5=0 RouterB##show ip protocols Routing Protocol is "eigrp 220" Outgoing update filter list for all interfaces is not set Incoming update filter list for all interfaces is not set Default networks flagged in outgoing updates Default networks accepted from incoming updates EIGRP metric weight K1=1, K2=1, K3=1, K4=0, K5=0 A. EIGRP is running on RouterA and OSPF is running on RouterB. B. There is an ACL set on the routing protocol. C. The AS numbers don t match. D. There is no default network accepted from incoming updates. E. The K values don t match. F. There is a passive interface set.

4 13. Which are true regarding EIGRP successor routes? (Choose two.) A. A successor route is used by EIGRP to forward traffic to a destination. B. Successor routes are saved in the topology table to be used if the primary route fails. C. Successor routes are flagged as active in the routing table. D. A successor route may be backed up by a feasible successor route. E. Successor routes are stored in the neighbor table following the discovery process. 14. The remote RouterB router has a directly connected network of /27. Which two of the following EIGRP network statements could you use so this directly connected network will be advertised under the EIGRP process? (Choose two.) A. network B. network C. network D. network RouterA and RouterB are connected via their Serial 0/0 interfaces, but they have not formed an adjacency. Based on the following output, what could be the problem? A. The metric K values don t match. B. The AS numbers don t match. C. There is a passive interface on RouterB. D. There is an ACL set on RouterA.

5 16. How many paths will EIGRPv6 load-balance by default? A. 16 B. 32 C. 4 D. None 17. What would your configurations be on RouterB based on the illustration? (Choose two.) A. (config)#router eigrp 10 B. (config)#ipv6 router eigrp 10 C. (config)#ipv6 router 2001:db8:3c4d:15::/64 D. (config-if)#ip eigrp 10 E. (config-if)#ipv6 eigrp 10 F. (config-if)#ipv6 router eigrp RouterA has a feasible successor not shown in the following output. Based on what you can learn from the output, which one of the following will be the successor for 2001:db8:c34d:18::/64 if the current successor fails? via FE80::201:C9FF:FED0:3301 ( /33316), Serial0/0/0 via FE80::209:7CFF:FE51:B401 ( /42216), Serial0/0/1 via FE80::209:7CFF:FE51:B401 ( /2816), Serial0/0/2 A. Serial0/0/0 B. Serial0/0/1 C. Serial0/0/2 D. There is no feasible successor.

6 19. You have router output as shown in the following illustrations with routers running IOS However, the two networks are not sharing routing table route entries. What is the problem? A. The variances don t match between routers. B. The metrics are not valid between neighbors. C. There is a discontiguous network. D. There is a passive interface on RouterB. E. An ACL is set on the router. 20. Which should you look for when troubleshooting an adjacency? (Choose four.) A. Verify the AS numbers. B. Verify that you have the proper interfaces enabled for EIGRP. C. Make sure there are no mismatched K values. D. Check your passive interface settings. E. Make sure your remote routers are not connected to the Internet. F.
