  Router R2 advertises the network 192.168.3.0/24 to router R1 via OSPF. A route policy has been constructed to discard the route on router R1; however, it is not working. What is the problem?

  A. The prefix list reject should be "192.168.3.0/16 exact".

  B. Router R1 should be configured as an OSPF "asbr".

  C. The policy "reject" should be set for import rather than export.

  D. The policy was likely not "committed" after creation.

  E. This is not possible because OSPF cannot use import policies.

  Correct Answer: E

• Question 764:

  What value should the AFI be set to for locally administered addressing?

  A. 1

  B. 49

  C. 47

  D. 45

  E. 39

  Correct Answer: B

• Question 765:

  When redistributing OSPF into RIP V2 what must be taken into consideration for the redistribution to take place?

  A. The metric must be set accordingly for RIP

  B. The subnet mask must be removed from the OSPF route

  C. You must divide the cost of the OSPF route by three

  D. The router must be configured as an ASBR

  Correct Answer: A

  What triggers convergence of the routing protocol when the link between switch 1 and switch 2 goes down?

  A. Convergence is triggered when the adjacency between routers R1 and R2 drops as a result of Hello timeouts. At this point, both routers R1 and R2 re-compute their link state database and send updates to their adjacent routers. Once the process is complete for all routers, the networks have converged.

  B. Convergence is triggered when the physical interfaces between routers R1 and R2 go down. At this point, both routers R1 and R2 re-compute their link state database and send updates to their adjacent routers. Once the process is complete for all routers, the networks have converged.

  C. Convergence will not be triggered because switches cannot run routing protocols between them.

  D. Convergence is triggered when the switches notify the routers about the link state information. At this point, both routers R1 and R2 re-compute their link state database and send updates to their adjacent routers. Once the process is complete for all routers, the networks have converged

  E. Convergence is triggered when an LSA is sent from router R1 to router R2 to indicate that the link is down. At this point, both routers R1 and R2 re-compute their link state database and send updates to their adjacent routers. Once the process is complete for all routers, the networks have converged.

  Correct Answer: A

• Question 767:

  What is the source IP address in an OSPF update?

  A. 224.0.0.5

  B. 224.0.0.6

  C. The unicast IP address of the interface the update is being sent on.

  D. The system address of the router

  Which of the following statements best describes the format of data traffic sent from the PC to the server?

  A. The source IP address will be the address of the PC, and the destination IP address will be the system IP address of router R1; the source MAC address will be the MAC address of the PC, and the destination MAC address will be the MAC address of the router R1 port connected to the PC.

  B. The source IP address will be the address of the PC, and the destination IP address will be the IP address of the router R1 port connected to the PC, the source MAC address will be the MAC address of the PC, and the destination MAC address will be the MAC address of the router R1 port connected to the PC.

  C. The source IP address will be the address of the PC, and the destination IP address will be the IP address of the server, the source MAC address will be the MAC address of the PC, and the destination MAC address will be the MAC address of the server.

  D. The source IP address will be the address of the PC, and the destination IP address will be the IP address of the server; the source MAC address will be the MAC address of the PC, and the destination MAC address will be the MAC address of the router R1 port connected to the PC.

  Correct Answer: D

• Question 769:

  How are LSPs acknowledged on IS-IS broadcast links?

  A. The LSP is acknowledged by sending a PSNP PDU.

  B. The LSP is acknowledged by sending an LSP PDU.

  C. The LSP is acknowledged by sending a Hello PDU.

  D. LSP are not acknowledged on broadcast links. The DIS sends periodic CSNPs to maintain database synchronization

  Correct Answer: D
