The command that displays the HSRP (Hot Standby Router Protocol) status and configuration details on a router is the "show standby" command. This command provides critical information about the HSRP groups configured on the router, including the virtual IP address, the priority of the router, which router is currently the active and standby router, and the timers for hello and hold times. It allows network administrators to check the operational status of the HSRP implementation and troubleshoot any potential issues. While there are other commands related to HSRP, they do not serve the same purpose. For example, there is no standard "show hsrp" command in the Cisco IOS that provides the same level of detail, nor does "display standby" exist in typical Cisco command syntax. The "check hsrp status" command does not exist either, making the "show standby" command the correct choice for retrieving HSRP status and configuration details.
