Question
Under which network type circumstance would an OSPF router establish router adjacencies while not performing the DR/BDR election process?

A. Point-to-point


B. Broadcast


C. Non-broadcast multi-access


D. Backbone area 0


E. None of the above
Answers
A
Explanation:
If there's a point to point connection, there's no need for a designated router or a backup designated router election since only two routers can exist on a point to point network segment.

Incorrect Answers:
B, C. All OSPF routers in a broadcast and non-broadcast multi-access network go
through the DR and BDR election process.


D. The backbone area is not a network type, but a collection of OSPF networks links.
Area 0 is reserved as the backbone area, and routers within area 0 may or may not go
through the DR/BDR election process, depending on the network type.   Your Comment
