What are two requirements for an HSRP group? (Choose two.)
Exactly one active router: Only one Active Router per HSRP group will be elected based on highest priority.
In case of equal priority, Highest IP address will be elected as Active Router.
One or more standby routers: There can be one or more Standby Routers.
Hot Standby Router Protocol (HSRP) is a Cisco proprietary protocol that provides redundancy for IP networks, allowing multiple routers to participate in a virtual router group that shares a virtual IP address.
The requirements for an HSRP group are as follows:
At least two routers must be configured to participate in the HSRP group.
Each router must be configured with the same group number, which identifies the virtual router group.
Based on these requirements, the correct answers are:
A. exactly one active router - This is incorrect. An HSRP group can have more than one active router, but only one router will be the active router at any given time.
B. one or more standby routers - This is correct. An HSRP group must have at least one standby router, which will take over as the active router if the current active router fails.
C. one or more backup virtual routers - This is incorrect. There is no such thing as a backup virtual router in HSRP.
D. exactly one standby active router - This is incorrect. There is no such thing as a standby active router in HSRP.
E. exactly one backup virtual router - This is incorrect. There is no such thing as a backup virtual router in HSRP.
Therefore, the correct answers are B) one or more standby routers and C) one or more backup virtual routers are incorrect.
