Q201. Refer to the exhibit. Will redistributed RIP routes from OSPF Area 2 be allowed in Area 1?

Select the best response.

A. Because Area 1 is an NSSA, redistributed RIP routes will not be allowed.

B. Redistributed RIP routes will be allowed in Area 1 because they will be changed into type 5 LSAs in Area 0 and passed on into Area 1.

C. Because NSSA will discard type 7 LSAs, redistributed RIP routes will not be allowed in Area 1.

D. Redistributed RIP routes will be allowed in Area 1 because they will be changed into type 7 LSAs in Area 0 and passed on into Area 1.

E. RIP routes will be allowed in Area 1 only if they are first redistributed into EIGRP.

Answer: A


Q202. Which show command will display only the Type 5 LSAs in the OSPF topology database? Select the best response.

A. show ip ospf database external

B. show ip ospf database nssa-external

C. show ip route ospf

D. show ip ospf database summary

E. show ip route

Answer: A


Q203. Which two statements are true about IBGP neighbor relationships? (Choose two.)

A. An EGP or static routing is required between IBGP neighbors.

B. A full-mesh IBGP requires that neighbor relationships be established between all BGP enabled routers in the autonomous system.

C. IBGP neighbors must be in different autonomous systems.

D. The BGP split-horizon rule specifies that routes learned via EBGP are never propagated to other IBGP peers.

E. The BGP split horizon rule specifies that routes learned via IBGP are never propagated to other IBGP peers.

Answer: BE


Q204. When learning a new route, if a LSA received is not found in the topological database, what will an internal OSPF router do?

A. The sequence numbers are checked, and if the LSA is valid it is entered into the topology database.

B. The LSA is placed in the topological database and an acknowledgement is sent to the transmitting router.

C. The LSA is dropped and a message is sent to the transmitting router.

D. The LSA is flooded immediately out of all the OSPF interfaces, except the interface from which the LSA was received.

Answer: D


Q205. Refer to the exhibit. Two routers are connected by Frame Relay and are running OSPF between them. Each router has been configured with the appropriate network statements under router ospf 1, but the routers are not forming an adjacency. Which of the following three commands could be configured on each router to correct this problem? (Choose three.)

A. RouterC(config-if)#ip ospf network broadcast

RouterD(config-if)#ip ospf network broadcast

B. RouterC(config-if)#ip ospf network point-to-point

RouterD(config-if)#ip ospf network point-to-point

C. RouterC(config-router)#neighbor 10.100.100.4

RouterD(config-router)#neighbor 10.100.100.3

D. RouterC(config-router)#neighbor 10.255.255.254

RouterD(config-router)#neighbor 10.255.255.253

Answer: ABD

Q206. Refer to the exhibit.

The neighbor 10.1.1.1 weight 200 BGP configuration command has been configured on router A.

What will be the result of this configuration?

A. Router A will prefer the path through router B for network 172.20.0.0

B. Router A will prefer the path through router C for network 172.20.0.0

C. Packets from router D will prefer the path through router B for networks advertised by router A

D. Packets from router D will prefer the path through router C for networks advertised by router A

Answer: A


Q207. Characteristics of the routing protocol EIGRP? (choose two.)

Select the 2 best responses.

A. Updates are sent as broadcast.

B. Updates are sent as multicast.

C. LSAs are sent to adjacent neighbors.

D. Metric values are represented in a 32-bit format for granularity. 

Answer: BD


Q208. What command should be used for a totally stubby area on the router connected to area 0 backbone?

Select the best response.

A. totally stubby on the ABR

B. stub no-summary on the ABR

C. totally stubby on all routers in the area

D. stub no-summary on the ASBR

E. stub no-summary on all routers in the area

F. totally stubby on the ASBR

Answer: B

A. show ip route bgp

B. show ip bgp

C. show ip bgp neighbors
