Which statement describes VRRP object tracking?

1. It monitors traffic flow and link utilization.

2. It ensures the best VRRP router is the virtual router master for the group.

3. It causes traffic to dynamically move to higher bandwidth links.

4. It thwarts man-in-the-middle attacks.

The correct answer is: It ensures the best VRRP router is the virtual router master for the group.

VRRP (Virtual Router Redundancy Protocol) object tracking is an important feature that enhances the functionality of VRRP by monitoring specific interfaces or routes associated with the virtual router. When a tracked object (like an interface or a route) goes down, the priority of the router is lowered, which may trigger a failover to a more capable backup router. This mechanism ensures that the best router, based on a dynamic assessment of health and status, takes over as the virtual router master for the group. This dynamic management allows for more reliable routing and ensures that even if the primary router encounters issues, traffic can still be rerouted effectively using the remaining operational routers. So, the correct statement accurately reflects the purpose of VRRP object tracking in maintaining network availability and performance.
