1. What are the three tables that EIGRP uses? (Choose three.) A. Route B. Broadcast C. Topology D. Neighbor E. Update 2. What are benefits of using a link-state routing protocol? (Choose two.) A. It uses the Hello protocol to establish adjacencies. B. It uses several components to calculate the metric of a route. C. Updates are sent only when changes occur in the network. D. It is always a better solution to implement than a distance-vector protocol. 3. How is EIGRP implemented on a router? A. ip router eigrp as B. router ip eigrp as C. router eigrp process-id D. router eigrp as 4. When the show ip route command is used, which of the following codes indicate an EIGRP learned route? A. D B. R C. S D. I 5. You want to use a routing protocol that utilizes the benefits of both distance vector and link state. Which routing protocol will you use? A. IP B. RIP C. EIGRP D. OSPF 6. You get a call from a network administrator who tells you that he typed the following into his router: Router#ospf 1 Router(config-router)#network 10.0.0.0 255.0.0.0 area 0 He tells you he still can’t see any routes in the routing table. What configuration error did the administrator make? A. The wildcard mask is incorrect. B. The OSPF area is wrong. C. The OSPF process ID is incorrect. D. The AS configuration is wrong. 7. Which of the following are used by default by EIGRP to calculate the best path to a destination network? (Choose two.)

A. Bandwidth B. Load C. Delay D. Reliability 8. Which of the following is true regarding OSPF areas? (Choose three.) A. You must have separate loopback interfaces configured in each area B. The numbers you can assign an area go up to 65535 C. The backbone area is also called area 0 D. If your design is hierarchical, then you don’t need multiple areas E. All areas must connect to area 0 F. If you have only one area, it must be called area 1 9. Which of the following network types have a designated router and a backup designated router assigned? (Choose two.) A. Broadcast B. Point-to-point C. NBMA broadcast D. NBMA point-to-point E. NBMA point-to-multipoint 10. Which of the following OSPF terms refers to a connected (or adjacent) router that is running an OSPF process, with the adjacent interface assigned to the same area? A. Link B. Neighbor C. LSA D. STP 11. What OSPF term refers to a network or router interface? A. Link B. Area C. LSA D. STP 12. Which of the following are advantages of OSPF over RIPv1? (Choose three.) A. Has higher convergence speed B. Is simple to configure C. Has support for VLSMs D. Has greater scalability 13. A network is being advertised from a neighbor EIGRP router, but your router has stopped receiving hello updates from this router, but the topology table has a feasible successor listed. What will EIGRP do?

A. Flood the network telling everyone that the advertised network is down B. Use the feasible distance as the new route, place it in the routing table, and start routing immediately C. Use the feasible successor as the new route, place it in the routing table and start routing immediately D. Place a holddown on the network 14. Which type of OSPF network will elect a backup designated router? (Choose two.) A. Broadcast Multiaccess B. Non-broadcast multi-access C. Point-to-point D. Broadcast multipoint 15. Which two of the following commands will place network 10.2.3.0/24 into Area 0? A. router eigrp 10 B. router ospf 10 C. router rip D. network 10.0.0.0 E. network 10.2.3.0 255.255.255.0 area 0 F. network 10.2.3.0 0.0.0.255 area0 G. network 10.2.3.0 0.0.0.255 area 0 16. What does EIGRP use to deliver routing information throughout the internetwork? A. DUAL B. RTP C. RTMP D. PDM 17. What are three reasons for creating OSPF in a hierarchical design? A. To decrease routing overhead B. To speed up convergence C. To confine network instability to single areas of the network D. To make configuring OSPF easier 18. What is the administrative distance of OSPF? A. 90 B. 100 C. 110 D. 120 19. Which of the following commands will display the RID? (Choose two.) A. show ip route B. show ip ospf C. show ip ospf interface D. show protocols

20. Which of the following will become the RID of a router by default if a router contains both logical and physical interfaces? A. The lowest IP address of any physical interface B. The highest IP address of any physical interface C. The lowest IP address of any logical interface D. The highest IP address of any logical interface
