You want to allow Router R1 to immediately become the active router if its priority is highest than the active router fails. What command would you use if you wanted to configure this?

A.
en standby 1 preempt

B.
standby 1 preempt enable

C.
standby 1 preempt

D.
hot standby 1 preempt

Explanation:

The HSRP preemption feature enables the router with highest priority to immediately become the Active router. Priority is determined first by the priority value that you configure, and then by the IP address. In each case a higher value is of greater priority. When a higher priority router preempts a lower priority router, it sends a coup message. When a lower priority active router receives a coup message or hello message from a higher priority active router, it changes to the speak state and sends a resign message. To configure preemption, use the "standby standby-number preempt" command.
