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

Answer: Option A

Solution(By Examveda Team)

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.
