The OSPF packets shown have been exchanged between two neighbors. What state is the OSPF adjacency in?
- A. The adjacency state is full. The routers are exchanging database description packets to notify each other that all link state advertisements have been received.
- 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.
- C. The adjacency state is two way because both routers have received a database description packet.
- D. The adjacency is in the exchange state. The next step is to exchange link state request and link state update packets.
Answer: B
NEW QUESTION 50

- A. Transparent to routing neighbors
- B. No protocol extensions required
- C. Uses Graceful Restart to inter-operate with other vendors
- D. Only supported by OSPF and IS-IS
Answer: A,B
NEW QUESTION 53

Which of the following statements regarding OSPF routing updates on a multi-access network segment is true?
- A. In multi-access networks, a DR and BDR are elected. To ensure resiliency, both the DR and BDR send link-state advertisements describing the network.
- B. In multi-access networks, a DR and BDR are elected only if there are more than two routers connected to the network segment.
- C. In multi-access networks, a DR and BDR are elected only if the subnet masks on the router interfaces are less than /30
- D. In multi-access networks, a DR and BDR are elected. The DR sends link-state advertisements describing the network.
