Question:
Which OSPF network types are compatible and allow communication through the two peering devices?

  • A. point-to-multipoint to nonbroadcast
  • B. broadcast to nonbroadcast
  • C. point-to-multipoint to broadcast
  • D. broadcast to point-to-point

Explanation: The following different OSPF types are compatible with each other:
+ Broadcast and Non-Broadcast (adjust hello/dead timers)
+ Point-to-Point and Point-to-Multipoint (adjust hello/dead timers)
Broadcast and Non-Broadcast networks elect DR/BDR so they are compatible. Point-topoint/ multipoint do not elect DR/BDR so they are compatible.
