• Question 187:

  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.
