Two Cisco routers are connected via a serial link with no other devices on the segment. The engineer configures OSPFv2 on both routers and notices that the adjacency forms quickly without any DR/BDR election. Which OSPF network type is most likely configured on this interface, and what state should the neighbor reach?

Point-to-multipoint; the neighbor should reach the ExStart state.

Broadcast; the neighbor should reach the Full state.

Point-to-point; the neighbor should reach the Full state.

Non-broadcast; the neighbor should reach the 2-Way state.

An engineer is adding a new router to an existing OSPFv2 broadcast segment that already has a DR and BDR. The new router has a higher router ID than the current DR. After the new router is connected and OSPF is enabled, what will be the role of the new router on this segment?

It will become the DR only if its OSPF priority is higher than the current DR's priority.

It will become the new DR immediately because it has the highest router ID.

It will remain a DROTHER until the current DR or BDR fails.

It will become the BDR immediately because it has the second-highest router ID.

Why is it important for the OSPFv2 Router ID to remain stable?

It must match the IP address of the interface used for OSPF updates.

It is used as the destination IP address for OSPF packets.

It determines the OSPF process ID.

It is used to identify the router in LSAs and routing table entries.
