Which failover detection protocol must be used to meet this requirement?

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

Answer: D

Explanation:

To support Equal-Cost Multi-Path (ECMP) routing in an NSX environment, Bidirectional Forwarding Detection (BFD) must be used for failover detection. BFD is a rapid failure detection protocol that works with ECMP to provide fast failure detection between routers. It helps in detecting link failures more quickly than traditional protocols, ensuring that traffic is routed through available paths as quickly as possible.
