Which statement describes VRRP object tracking?
A.
It monitors traffic flow and link utilization.
B.
It ensures the best VRRP router is the virtual router master for the group.
C.
It causes traffic to dynamically move to higher bandwidth links.
D.
It thwarts man-in-the-middle attacks.
VRRP allows for transparent failover at the first-hop IP router by configuring a group of routers to share a virtual IP address.
VRRP selects a master router in that group to handle all packets for the virtual IP address.
VRRP supports the following two options for tracking:
Object tracking— determine the priority (the best) of VRRP router in a VRRP group.
Native interface tracking— Tracks the state of an interface and uses that state to determine the priority of the VRRP router in a VRRP group. The tracked state is down if the interface is down or if the interface does not have a primary IP address.

Object tracking is the process of tracking the state of a configured object and uses that state to determine the priority of the VRRP router in a VRRP group -> B is correct.
Note: Unlike HSRP which can track interface status directly, VRRP can only track interface status through a tracked object.

The Virtual Router Redundancy Protocol (VRRP) is a computer networking protocol that provides for automatic assignment of available Internet Protocol (IP) routers to participating hosts. This increases the availability and reliability of routing paths via automatic default gateway selections on an IP subnetwork
