What is the purpose of disabling VRRP preempt?

1. To allow the current master router to maintain status after recovery

2. To enable quick failover to backup routers

3. To ensure that VRRP does not initiate election processes

4. To permit configuration changes without impacting network performance

The correct answer is: To allow the current master router to maintain status after recovery

Disabling VRRP (Virtual Router Redundancy Protocol) preempt is primarily aimed at allowing the current master router to maintain its status even after recovering from a failure. When preempt is disabled, if the currently active master router goes down and then comes back up, it will not automatically reclaim its master status. Instead, the router that took over as master remains in that role until it fails or is manually configured otherwise. This behavior is beneficial for maintaining stability in the network, as it prevents unnecessary flapping between routers and allows the active router to provide uninterrupted service. The other options do not accurately reflect the implications of disabling preempt. While quick failover and preventing election processes may sound advantageous, they do not specifically relate to the status retention of the active master router after recovery. Moreover, permitting configuration changes without impacting network performance is not a purpose of disabling VRRP preempt; instead, configuration changes typically require careful planning to avoid network disruption regardless of this setting.
