What are two requirements for an HSRP group? (Choose two.)

HSRP (Hot Standby Router Protocol) ensures high network availability by allowing multiple routers to share a single virtual IP address and MAC address. For an HSRP group to function correctly, there must be exactly one active router responsible for forwarding traffic. This active router is elected based on priority or IP address. Additionally, there must be one or more standby routers ready to take over if the active router fails. These standby routers monitor the active router's status. "One or more backup virtual routers" and "exactly one backup virtual router" are incorrect because HSRP uses the terms "active" and "standby" routers, not "backup virtual routers." "Exactly one standby active router" is a contradiction in terms; a router is either active or standby.
