Question

Which feature must be configured for the VRRP-enabled router to regain the master VRRP status upon recovery from a failure?

Options

Apriority
Bauthentication
Cpre-emption
DStateful Switchover

Explanation

VRRP preemption (enabled by default in VRRP) allows a router with a higher priority value to automatically take back the Master role from the current Master when it recovers from a failure. Without preemption enabled, the higher-priority router would come back online but remain in the Backup state, leaving a lower-priority router as Master indefinitely. Priority alone determines which router should be Master, but preemption is the mechanism that enforces the takeover. Authentication secures the VRRP messages, and Stateful Switchover is a Cisco IOS feature for supervisor redundancy, not VRRP role recovery.
