CCNA: Cisco Certified Network Associate — Question 394

What is a benefit of VRRP?

Answer options

• A. It provides the default gateway redundancy on a LAN using two or more routers.
• B. It provides traffic load balancing to destinations that are more than two hops from the source.
• C. It prevents loops in a Layer 2 LAN by forwarding all traffic to a root bridge, which then makes the final forwarding decision.
• D. It allows neighbors to share routing table information between each other.

Correct answer: A

Explanation

The correct answer is A because VRRP (Virtual Router Redundancy Protocol) is specifically designed to provide redundancy for the default gateway in a LAN by using multiple routers. Options B, C, and D describe functionalities related to load balancing, loop prevention, and routing information exchange that are not the primary purpose of VRRP.
