Implementing Cisco Enterprise Advanced Routing and Services (ENARSI) — Question 386

What is considered the primary advantage of running BFD?

Answer options

• A. reduction in time needed to detect Layer 3 routing neighbor failures
• B. reduction in CPU needed to detect Layer 3 routing neighbor failures
• C. reduction in time needed to detect Layer 2 switched neighbor failures
• D. reduction in CPU needed to detect Layer 2 switch neighbor failures

Correct answer: A

Explanation

The primary advantage of running BFD is the rapid detection of Layer 3 routing neighbor failures, which allows for quicker failover and improved network reliability. Options B, C, and D focus on CPU usage or Layer 2 issues, which are not the main benefits of BFD.
