Q10. What are the three major advantages of hierarchical nature of OSPF? [Choose 3].

A. Reduced number of SPF calculations.

B. Increased complexity of management

C. Smaller routing tables.

D. Reduced LSU overhead.

Correct Answer: A,C,D

Explanation:

The major advantages of hierarchical nature of OSPF are:
1. Reduced frequency of SPF calculations: This is because the packets are flooded only within an area, and not to the other areas.
2. Smaller routing tables: Routes can be summarized when being advertised out side an area, thus reducing the routing table entries.
3. Reduced LSU overhead: Fewer number of LSUs can be sent with a single or fewer summarized routes between areas to reduce the overhead associated with link-state updates when they are crossing areas.
