Designing Cisco Network Service Architectures (ARCH, legacy) — Question 29

Which virtualization technology uses Layer 3 BFD to detect network failures between network devices?

Answer options

• A. VTP
• B. VSS
• C. vPC
• D. Cisco Fabric Path

Correct answer: D

Explanation

Cisco Fabric Path is the correct answer because it utilizes Layer 3 Bidirectional Forwarding Detection (BFD) to monitor and quickly detect network failures. VTP, VSS, and vPC do not specifically implement Layer 3 BFD for failure detection, making them unsuitable for this particular function.
