Refer to the exhibit. The partial configuration for an OSPF ASBR and an Area 0 ABR is shown. Assume the OSPF configurations throughout the network are operable. Which statement about these configurations is true?




A.       The ASBR route-maps are basically useless, because there are no deny prefix-lists.

B.       LSA Type 5s will not be received by the ABR from the ASBR.

C.       The OSPF backbone will not learn any RFC 1918 addresses.

D.      The matched prefix-list addresses will be given a metric of 255, which is essentially unreachable.


Correct Answer: C
















Refer to the exhibit. Examine the partial configuration and the routing table excerpt. Which routes would be redistributed into OSPF area 1?




A. only

B. and

C.,, and

D. only


Correct Answer: D




Which two statements about route redistribution when implementing OSPF are true? (Choose two.)


A.       Routes learned using any IP routing protocol can only be redistributed into non IP routing protocols.

B.       OSPF can import routes learned using EIGRP, RIP, and IS-IS.

C.       OSPF routes cannot be exported into EIGRP, RIP, and IS-IS.

D.       At the interdomain level, OSPF cannot import routes learned using BGP.

E.        OSPF routes can be exported into BGP.


Correct Answer: BE




Which two routing interface parameters are supported in OSPF implementations? (Choose two.)


A.       retransmit-interval

B.       dead-i

C.       stub area

D.      virtual link

E.       NSSA area


Correct Answer: AB




Refer to the exhibits.




You are verifying your OSPF implementation, and it does not seem to be functioning properly. What can you conclude from the exhibit and the show running-configuration command output?


A.       The OSPF areas are not configured correctly.

B.       The wildcard masks for the 10.x.x.x networks are incorrect.

C.       The 172.16.x.x networks need to be connected to area 0 using virtual links.

D.      The 172.16.x.x networks are discontiguous. OSPF is automatically summarizing them to and data is being “black holed.”

E.       There is not enough information to make a determination.


Correct Answer: A




OSPF is enabled on router A. You execute the following command on router A and receive the accompanying output:

clip_image006 is the IP address of a loopback interface on router A, What can you conclude about router A?


A.       Only the router A loopback interface is participating in the OSPF routing process.

B.       None of the router A interfaces are participating in the OSPF routing process.

C.       Router A is using the loopback interface IP address as its OSPF router ID.

D.      Router A does not have any reachable OSPF neighbors.


Correct Answer: D















Refer to the exhibit. What is the effect of the OSPF configuration on router B?




A.       All interfaces will be in area 0.

B.       The router will b
e an ABR with s1/0 in area 0 and f0/0 and 0/1 in area 1.

C.       The router will be an ABR with s1/0 in area 0 and f0/0 and 0/1 in area 2.

D.      The router will be an ABR with s1/0 in area 0, f0/0 in area 1, and f0/1 in area 2.


Correct Answer: D
















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



D.  RouterC(config-router)#neighbor



Correct Answer: ABD








Your network has a mixture of Fast Ethernet and Gigabit Ethernet links. What needs to be done to ensure optimal data routing when using OSPF?


A.       Nothing. OSPF will determine the most optimal path for routing data by default.

B.       Adjust the hello and dead timers for more rapid detection of link

C.       Increase the reference-bandwidth used to calculate the interface default metrics, on all routers in your network.

D.      Set the priority values on every broadcast interface to ensure that the designated and backup designated routers are the routers with the most processor and memory resources.


Correct Answer: C




To make OSPF area 4 a totally stubby area, which two things need to be done? (Choose two.)


A.       Apply the area 4 stub command to all routers in the area.

B.       On the ABR, use the area 4 stub command with the no-summary keyword.

C.       On the ABR, specify a default cost for the area with the area default-cost command.

D.      On the ABR, use the default-information originates command to inject a default route into area 4.

E.       Use the auto-cost command on each router in the area to automatically determine the cost to other OSPF areas.
