Two distribution routers, R1 and R2, share a single HSRP group on a user VLAN to provide a redundant default gateway. The hosts point at the group's virtual IP address. Which two statements correctly describe how this HSRP group operates? Select TWO.
- ABoth routers forward host traffic to the virtual IP at the same time, sharing the load equally across the group.
- BOnly the active router forwards traffic sent to the virtual IP, while the standby router monitors it and takes over on failure. Correct
- CThe active router answers ARP for the virtual IP with a shared virtual MAC address rather than its own burned-in address. Correct
- DEach host must be configured with both routers' real interface addresses so it can switch gateways if the active fails.
- EA router with a lower configured priority value is preferred and becomes the active forwarder for the group.
Why A is wrong: It sounds efficient because two routers are present, but standard HSRP runs one active forwarder while the other waits as standby; simultaneous forwarding within one group is GLBP behaviour, not HSRP.
Why B is correct: HSRP elects one active router to forward for the virtual IP and one standby that tracks the active via hellos and assumes the role if the active stops responding.
Why C is correct: Hosts resolve the virtual IP to a group virtual MAC, so when the standby takes over it owns that same virtual MAC and host ARP caches need no update.
Why D is wrong: It seems to add resilience, but the whole point of HSRP is that hosts use only the single virtual IP; they never need either router's real address or any reconfiguration on failover.
Why E is wrong: Priority direction is easy to invert, but HSRP prefers the higher priority value for active; the lower-priority router becomes standby, so this reverses the rule.
