Verify Router Priority in HSRP Group

D.

The following is sample output from the show standby command:

The correct command to verify the priority of a router in an HSRP (Hot Standby Router Protocol) group is the "show standby" command, option D.

HSRP is a Cisco proprietary protocol that allows two or more routers to participate in a virtual router group to present the appearance of a single virtual router to the hosts on a LAN. The virtual router is represented by a virtual IP address that is shared among the routers in the group. The HSRP group uses a priority value to determine which router in the group will be the active router and which router will be the standby router.

To verify the priority of a router in an HSRP group, you can use the "show standby" command followed by the interface name where HSRP is configured. This command will display the HSRP group information, including the current priority of the router, as well as the priority of the other routers in the group, the current active router, and other related HSRP parameters.

For example, to verify the HSRP status of interface VLAN 10, you can enter the following command:

sqlCopy code
show standby vlan 10 

This command will display the status of the HSRP group for VLAN 10, including the current priority of the router and other information about the HSRP group. The output will look something like this:

vbnetCopy code
Vlan10 - Group 10   State is Active     10 priority     Preemption enabled     Active router is local     Standby router is 10.1.1.2, priority 90 (expires in 00:00:08)     Virtual IP address is 10.1.1.1 

In this example, the local router has a priority of 10, which is higher than the priority of the standby router (90), so it is the active router in the HSRP group for VLAN 10.
