What causes an adjacency to change from down to two ways?

  1. When a link state update is received in response to a link state request.
  2. When a router receives a Hello packet that contains its own router ID in the neighbor list from a neighbor.
  3. When a router receives a database description packet from a neighbor.
  4. When a link state acknowledgement is received in response to a link state update.

Answer(s): B

In the topology shown, router R1 is an ASBR configured to export external routes to OSPF. Assuming that there are no stub networks, which of the following statements regarding type 4 LSA generation is true?

  1. Router R1 generates a type 4 LSA that is flooded to areas 0, 1, and 2.
  2. Router R3 generates a type 4 LSA that is flooded to areas 0, 1, and 2.
  3. Router R3 generates a type 4 LSA that is flooded to areas 0 and 2.
  4. Router R3 generates a type 4 LSA that is flooded to area 0, and router R6 generates a type 4 LSA that is flooded to area 2.

Answer(s): D



Which of the following commands can be used to display the number of SPF computations that have been performed on a router?

  2. show router ospf neighbor
  3. show router ospf interface
  4. show router ospf status

Answer(s): A

What can you deduce from the show command on router R6?

  1. The router R6 interface is in a multi-access segment. It is neither the DR nor the BDR for the segment. The DR for this segment would be the router with router ID 10.10.10.5.
  2. The router R6 interface is in a multi-access segment. It is neither the DR nor the BDR for the segment; however, this command does not indicate whether 10.10.10.3 or 10.10.10.5 is the DR or BDR.
  3. The router R6 interface is in a multi-access segment. It is the BDR, which is why it is not adjacent to the other routers.
  4. The router R6 interface is in a multi-access segment. It is neither the DR nor the BDR for the segment. The DR for this segment would be the router with router ID 10.10.10.3.

Answer(s): B
