Question 31 🔥

If OSPF is used in a multi-area OSPF network, which of the following statements regarding route summarization is true?

Which database solution meets these requirements?

A. Manual route summarization can only be done on autonomous system border routers.

Highly voted

B. Manual route summarization must be done on all the backbone routers to be effective. Manual route summarization is optional on the routers in non-backbone areas.

Highly voted

C. Manual route summarization is done on the ABRs. By default, automatic summarization is done; however, it may not be optimal for all networks.

Highly voted

Question 32 🔥

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

Which database solution meets these requirements?

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

Highly voted

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

Highly voted

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.

Highly voted

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.
