Implementing Cisco Enterprise Advanced Routing and Services (ENARSI) — Question 510

What is the failure detection time with BFD?

Answer options

• A. 3 seconds
• B. less than a second
• C. 2 seconds
• D. 1 second

Correct answer: B

Explanation

The correct answer is B, as BFD (Bidirectional Forwarding Detection) is designed to detect failures in less than a second, allowing for rapid recovery. Options A, C, and D are incorrect because they suggest longer failure detection times that do not align with BFD's capabilities.
