• Question 232:

  Which of the following statements regarding link state protocols are true? (Choose two)

  A. When a router receives updates from its neighbors, it adds them to its link state database, performs an SPF computation, and sends the results to its neighbors.
  B. An SPF computation is done by each router to determine the best path to destination networks. All the best paths determined by the SPF calculation will be seen in the route table.
  C. Each router constructs its own link state database with updates received from neighbors.
  D. An SPF computation is done by each router to determine the best path to destination networks. All the best paths determined by the SPF calculation will be offered to the route table manager.
  C. Each router constructs its own link state database with updates received from neighbors.

  Router R2 uses OSPF to advertise the network 192.168.3.0/24 to router R1. A route policy has been configured to reject the route on router R1. Why doesn't the route policy work?

  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 was not "committed" after creation.
  D. Router R1 cannot reject the route because OSPF does not support import policies
