Two OSPF routers are connected via a point-to-point link. They are not forming an adjacency. You check the OSPF neighbor table and see that each router is not listing the other as a neighbor. You have verified that the Hello and Dead intervals match, the area ID is the same, and authentication is configured identically. What is the most likely cause?

The OSPF network type is broadcast on one side and point-to-point on the other.

The link is administratively down on one side.

The routers are in different OSPF areas.

The OSPF cost is different on the two interfaces.

What is the primary purpose of the Designated Router (DR) on a broadcast multi-access network?

To assign router IDs to other routers

To forward packets between routers

To reduce the number of OSPF adjacencies

You are troubleshooting an OSPF adjacency between two routers. The neighbor state is stuck in ExStart. You have verified that the MTU matches and the network type is consistent. What is the most likely cause of the problem?

The routers cannot agree on the master/slave relationship.

The Dead interval is too short.

The OSPF authentication key is incorrect.

The OSPF cost is different on the two interfaces.
