The command "standby group preempt" in Hot Standby Router Protocol (HSRP) enables a router that is configured as a standby router to take over the active role when it has a higher priority or when it becomes available again after a failure. This command ensures that once the original active router comes back online or is restored to an operational state, it can reclaim the active role, thus providing improved network reliability and fault tolerance.

In HSRP, when a router is configured with the "preempt" command, it means that the router is allowed to preemptively take control of the active role as long as its priority is higher than the currently active router. This allows for more efficient management of active and standby routers and helps maintain the desired active router configuration in terms of priority settings.

The other options reflect actions or behaviors that do not align with the primary function of the "standby group preempt" command, which is specifically tailored for restoring the active router's role after recovery.
