VRID stands for which term?

• A. Virtual Router ID - UUID for the pair of HA devices on the subnet
• B. Virtual Routing ID
• C. VLAN Router ID
• D. Virtual Resource Identifier

Answer: (A)

VRID is the identifier used by VRRP to designate the virtual router that a high-availability pair presents on a subnet. It's a numeric ID that all devices on the subnet use to elect and refer to the active master for that virtual router, enabling seamless failover without changing IPs. The best match is Virtual Router ID because that term precisely names the identifier for the VRRP-managed virtual router. The extra phrase about a UUID for the HA pair isn’t how VRID is defined; VRID is not a UUID but the router-identity used by VRRP. The other terms don’t align with the standard VRID meaning.
