Which one of the following statements regarding Bidirectional Forwarding Detection (BFD) is correct?

Answer options

• A. BFD echo mode is the default mode of operation.
• B. BFD is not supported for HSRP.
• C. CEF must be disabled for BFD to work.
• D. BFD is not supported when using static routes.

Correct answer: A

Explanation

The correct answer is A because BFD echo mode is indeed the default operational mode, allowing for efficient monitoring of the link between two endpoints. Options B, C, and D are incorrect as BFD is supported for HSRP, does not require CEF to be disabled, and can work with static routes.
