Which command is used to configure the association between VRRP and a physical interface?

The command "vrrp vrid 1 track interface GigabitEthernet0/0/0" is used to configure the association between Virtual Router Redundancy Protocol (VRRP) and a physical interface. In this context, VRRP is utilized to provide redundancy for IP addresses on a network and to ensure that traffic is routed efficiently even in cases of failure.

When configuring VRRP, tracking an interface allows the VRRP router to monitor the state of that interface. If the tracked interface goes down, the router can make decisions based on that state change, such as transitioning the VRRP master role to another router. The correct command properly specifies that VRRP with ID 1 should track the state of the physical interface GigabitEthernet0/0/0, thereby enabling dynamic adjustment of the VRRP master based on the operational status of the interface.

In contrast, the other choices either do not correctly implement the tracking of the interface or present the command structure in an incorrect format. Therefore, the correct choice effectively establishes the necessary association between VRRP and the specific physical interface, which is crucial for maintaining high availability and redundancy in a network environment.
