VMware NSX-T Data Center (VCP-NV 2020) — Question 56

An NSX administrator wants to create a Tier-0 Gateway to support equal cost multi-path (ECMP) routing.
Which failover detection protocol must be used to meet this requirement?

Answer options

• A. Beacon Probing (BP)
• B. Host Standby Router Protocol (HSRP)
• C. Bidirectional Forwarding Detection (BFD)
• D. Virtual Router Redundancy Protocol (VRRP)

Correct answer: C

Explanation

Bidirectional Forwarding Detection (BFD) is essential for rapid detection of failures in the network, making it ideal for ECMP routing. The other options, such as HSRP and VRRP, are used for router redundancy rather than ECMP support, while Beacon Probing (BP) is not specifically designed for routing failover detection.
