  OSPF router R2 has both point-to-point and broadcast interfaces and it is not a DR for any interfaces. Router R2 detects the link failure between itself and router R1.

  Which of the following is correct?

  A. Router R2 sends an update to 224.0.0.5 on its broadcast and point-to-point interfaces. The DR does not send any updates.

  B. Router R2 sends an update to 244.0.0.5 on its point-to-point interfaces. The DR sends an update to

  224.0.0.6 on the broadcast network.

  C. Router R2 sends an update to 224.0.0.5 out its point-to-point interfaces and an update to 224.0.0.6 out its broadcast interface. The DR sends updates to 224.0.0.5 on the broadcast network.

  D. Router R2 sends an update to 224.0.0.6 out its point-to-point interfaces and an update to 224.0.0.5 out its broadcast interface. The DR sends an update to 224.0.0.6 on the broadcast networks.

  Correct Answer: C

• Question 14:

  What are the three databases that are maintained by a link-state protocol?

  A. Neighbor, adjacency, routing.

  B. Neighbor, topology, forwarding.

  C. Topology, routing, forwarding.

  D. Topology, forwarding, traffic classification.

  E. Neighbor, adjacency, forwarding.

  Correct Answer: B

• Question 15:

  Which of the following regarding IS-IS DIS is FALSE?

  A. L1 and L2 routers elect separate DIS's.

  B. DIS uses a specific Ethernet multicast address to communicate with other routers on the broadcast network.

  C. If a new router starts up in a LAN and has a higher interface priority, the new router preempts the original DIS and becomes the DIS.

  D. In broadcast multi-access networks, such as Ethernet, one router is elected as the DIS and a second router as the backup DIS.

  Correct Answer: D

• Question 16:
