Implementing Cisco Enterprise Advanced Routing and Services (ENARSI) — Question 342

What is the function of BFD?

Answer options

• A. It creates high CPU utilization on hardware deployments
• B. It provides uniform failure detection on the same media type
• C. It provides uniform failure detection regardless of media type
• D. It negotiates to the highest version if the neighbor version differs

Correct answer: C

Explanation

The correct answer is C because BFD (Bidirectional Forwarding Detection) is designed to provide rapid failure detection across various media types, ensuring that network failures are recognized quickly. Options A and B are incorrect as they misrepresent BFD's purpose, and option D, while it describes a feature of some protocols, does not pertain to BFD's primary function.
