CCNA: Cisco Certified Network Associate — Question 347

What is the purpose of using First Hop Redundancy Protocol on a specific subnet?

Answer options

• A. forwards multicast hello messages between routers
• B. sends the default route to the hosts on a network
• C. ensures a loop-free physical topology
• D. filters traffic based on destination IP addressing

Correct answer: B

Explanation

The correct answer is B because First Hop Redundancy Protocol is designed to provide a default gateway for hosts on a network, ensuring they can always reach a gateway even if one becomes unavailable. The other options do not accurately describe the primary role of this protocol, as A relates to router communication, C pertains to topology issues, and D is about traffic filtering.
