300-420 · Question #17
Which two statements about VRRP object tracking are true? (Choose two)
The correct answer is A. The priority of a VRRP device can change in accordance with the up or down status of a VRRP D. VRRP can track the status of interfaces and routes. VRRP object tracking allows a VRRP device's priority to dynamically change based on the status of monitored objects, which can include both interfaces and routes.

Why each option
VRRP object tracking allows a VRRP device's priority to dynamically change based on the status of monitored objects, which can include both interfaces and routes.
VRRP object tracking enables monitoring of specific objects (like an interface or route), and when a tracked object's status changes, the VRRP router's priority can be automatically decremented, potentially triggering a master role change.
While VRRP interface priority is often manually configured, object tracking allows for dynamic changes to this priority, making the statement that it must be manually configured incorrect.
A VRRP group can track multiple objects simultaneously; multiple 'track' commands, each with its own decrement value, can be associated with a single VRRP group.
VRRP can be configured to track the status of various network objects, including the line protocol or IP routing reachability of specific interfaces and the availability of IP routes, to influence its master election process.
This statement is incorrect because VRRP supports tracking various objects, including routes, not exclusively interfaces.
