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

NEW QUESTION # 21
Which of the following statements regarding OSPF routing updates on a point-to-point link is true?
- A. On a point-to-point link, there is no need for a DR and BDR election; all routing updates are sent to 224.0.0.5.
- B. On a point-to-point link, a DR and BDR are elected. The DR sends link-state advertisements describing the network.
- C. On a point-to-point link, a DR and BDR are elected. To ensure resiliency, both the DR and BDR send link-state advertisements describing the network.
