EIGRP and OSPF - Technical MCQs

Q1:

What are reasons for creating OSPF in a hierarchical design?
  1. To decrease routing overhead
  2. To speed up convergence
  3. To confine network instability to single areas of the network
  4. To make configuring OSPF easier

A 1, 2 and 3

B 3 only

C 3 and 4

D 2, 3 nd 4

ANS:A - 1, 2 and 3

OSPF is created in a hierarchical design, not a flat design like RIP. This decreases routing overhead, speeds up convergence, and confines network instability to a single area of the network.
