CCNA: Cisco Certified Network Associate — Question 223
What is the primary purpose of a First Hop Redundancy Protocol?
Answer options
- A. It allows directly connected neighbors to share configuration information
- B. It reduces routing failures by allowing Layer 3 load balancing between OSPF neighbors that have the same link metric
- C. It allows a router to use bridge priorities to create multiple loop-free paths to a single destination
- D. It reduces routing failures by allowing more than one router to represent itself as the default gateway of a network
Correct answer: D
Explanation
The correct answer is D because First Hop Redundancy Protocols are designed to provide redundancy for the default gateway, ensuring that if one router fails, another can take over without interruption. Options A, B, and C do not accurately describe the purpose of these protocols, as they focus on neighbor communication, load balancing, and loop-free paths rather than default gateway redundancy.
