HSRP (Hot Standby Router Protocol) is a Cisco proprietary protocol that provides redundancy for IP networks by allowing two or more routers to work together to present the appearance of a single virtual router.
To configure an HSRP group, the following two requirements must be met:
At least one active router: The active router is the router in the HSRP group that is currently forwarding packets sent to the virtual IP address. There must be at least one active router in an HSRP group to provide network redundancy.
One or more standby routers: The standby router is the router in the HSRP group that takes over as the active router if the current active router fails. There can be one or more standby routers in an HSRP group to provide redundancy in case the active router fails.
Therefore, the correct answers are A) exactly one active router and B) one or more standby routers.
Option C, one or more backup virtual routers, and Option E, exactly one backup virtual router, are not correct requirements for an HSRP group. HSRP does not have a concept of backup virtual routers.
Option D, exactly one standby active router, is also not a correct requirement for an HSRP group. HSRP does not have a concept of standby active routers.
