On which of the following networks will OSPF elect a designated router (DR)? (Choose two.)

  • Broadcast
  • NBMA
  • Point-to-point
  • Point-to-multipoint
Explanation:
OSPF will perform an election for a designated router (DR) and backup designated router (BDR) on every multi-access network segment. Multi-access segments are defined as segments where more than two hosts can reach each other directly, such as a shared Ethernet segment (broadcast multi-access) or Frame Relay (non-broadcast multi-access, or NBMA).

DR and BDR elections do not occur on point-to-point or point-to-multipoint segments. Point-to-point and point-to-multipoint segments are not considered multi-access segments. OSPF routers on these network types will establish an adjacency without a DR/BDR election.

Objective:
Routing Fundamentals
Sub-Objective:
Configure, verify, and troubleshoot single area and multi-area OSPFv2 for IPv4 (excluding authentication, filtering, manual summarization, redistribution, stub, virtual-link, and LSAs)
