EIGRP and OSPF - Technical MCQs

Q1:

With which network type will OSPF establish router adjacencies but not perform the DR/BDR election process?

A Point-to-point

B Backbone area 0

C Broadcast multi-access

D Non-broadcast multi-access

ANS:A - Point-to-point

No DR is assigned on any type of point-to-point link. No DR/BDR is assigned on the NBMA point-to-multipoint due to the hub/spoke topology. DR and BDR are elected on broadcast and non-broadcast multi-access networks. Frame Relay is a non-broadcast multi-access (NBMA) network by default.
