350-401 · Question #555
Refer to the exhibit. An engineer configures VRRP and issues the show commands to verify operation. What does the engineer confirm about VRRP group 1 from the output?
The correct answer is D. R1 is master if 10.10.1.1/32 is in its routing table. The engineer confirms that R1's master status for VRRP group 1 is conditional on the presence of the 10.10.1.1/32 route in its routing table, indicating VRRP object tracking is configured.

Why each option
The engineer confirms that R1's master status for VRRP group 1 is conditional on the presence of the 10.10.1.1/32 route in its routing table, indicating VRRP object tracking is configured.
The output of 'show vrrp' commands on R1 confirms its own VRRP state and tracked objects, not the routing table contents of R2.
If R1 reboots, R2 would become master, but R1 would regain mastership upon coming back online and meeting priority criteria if preemption is enabled, not just until R2 reboots.
The provided choices and typical VRRP configurations do not inherently confirm MD5 encryption; VRRP uses plain text by default or MD5 if explicitly configured, which isn't stated or implied as the confirmation point.
VRRP object tracking allows the router's priority to dynamically adjust based on the reachability of a tracked object, such as a specific IP route. If R1 is configured to track the route to 10.10.1.1/32, its VRRP priority will decrease if that route becomes unreachable, potentially forcing a failover and ensuring R1 is master only when it can properly route traffic for that destination.
Concept tested: VRRP object tracking for high availability
