The 192.168.4.0 network is not included in the RIP configuration of R2. 18. Which two statements are true about the EIGRP successor route? (Choose two.) It is used by EIGRP to forward traffic to the destination. 19. Refer to the exhibit. Hosts on the 192.168.1.0 network cannot communicate with hosts on the 172.16.1.1 network. The network administrator has run the show ip route command on R1. What could be the cause of this problem? No static route or routing protocol is configured. 20. Which statement correctly describes a feature of RIP? RIP uses only one metric—hop count— for path selection. 21. Refer to the exhibit. Which two statements are true based on the exhibited output? (Choose two.) All routes are stable. The show ip eigrp topology command has been run on R1. 22. A network administrator is analyzing routing update behavior on a network that has both EIGRP and OSPF configured on all routers. Both protocols appear in the output of show ip protocols. However, only EIGRP internal routes appear in the routing tables.

Which statement correctly explains the scenario? The EIGRP protocol has a lower administrative distance than OSPF 23. Which prompt is used to allow a user to change the IP address of an interface on a router? Router(config-if)# 24. Refer to the exhibit. Routers RTRA and RTRB are running OSPF. What entry does RTRA add in the routing table when Serial 0/0/0 receives an update about the network that is attached to RTRB? O 172.16.7.16/28 via 10.10.10.2, 00:00:25, Serial0/0/0 25. Which additional piece of information is included in the updates of classless routing protocols to support the use of VLSM and discontiguous networks? network mask 26. Because of a topology change, the next hop IP address in the current static route must be reconfigured. How can a static route entry be altered to accommodate a topology change? Negate the existing static route and configure a new static route with the correct next hop IP address. 27. Which router mode is accessed by entering the enable command? privileged EXEC 28.
