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

  A. 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.

  B. 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.

  C. 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.

  D. 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.

  Correct Answer: B

  The OSPF packets shown have been exchanged between two neighbors. What state is the OSPF adjacency in?

  A. The adjacency state is two way because both routers have received a database description packet.

  B. The adjacency is in the exchange state. The next step is to exchange link state request and link state update packets.

  C. The adjacency is in the ex start state. The routers have exchanged database description packets, but still have to negotiate the starting sequence number.

  D. The adjacency state is full. The routers are exchanging database description packets to notify each other that all link state advertisements have been received.
