An engineer is configuring GigabitEthernet1/0/0 for VRRP.
When the router has the highest priority in group 5, it must assume the master role.
Which command set should the engineer add to the configuration to accomplish this task? interface GigabitEthernet1/0/0 description To IDF A 38-70-774-10 ip address 172.16.13.2 255.255.255.0

To configure VRRP on a router, you need to specify the virtual IP address and group number, which identifies the VRRP group to which the router belongs. You also need to configure a priority for the router in the group, which determines whether it becomes the master or backup router for the virtual IP address. Additionally, you can configure preempt to allow the router to take over as the master if it has a higher priority than the current master. You can also use track to adjust the router's priority based on the status of another interface or object.
Looking at the answer choices:
A. standby 5 ip 172.16.13.254 standby 5 priority 100 standby 5 track 1 decrement 10
This command set configures VRRP with group number 5 and virtual IP address 172.16.13.254. The priority is set to 100, which is higher than the default priority of 100, so this router will be the master for the virtual IP address. The track option is used to adjust the priority based on the status of another object (in this case, object 1). If object 1 goes down, the priority will be decremented by 10, which could cause the router to lose its master status.
B. standby 5 ip 172.16.13.254 standby 5 priority 100 standby 5 preempt
This command set is similar to option A, except that it includes the preempt option. This allows the router to take over as the master if it has a higher priority than the current master, without waiting for the current master to fail. Since the priority is already set to 100, which is higher than the default priority, this option will also cause the router to be the master for the virtual IP address.
C. vrrp 5 ip 172.16.13.254 vrrp 5 priority 100
This command set is similar to option A, except that it uses the vrrp command instead of standby. Both commands are used to configure VRRP, but the syntax is slightly different. Again, the priority is set to 100, which is higher than the default priority, so this router will be the master for the virtual IP address.
D. vrrp 5 ip 172.16.13.254 255.255.255.0 vrrp 5 track 1 decrement 10 vrrp 5 preempt.
This command set is similar to option C, except that it includes the subnet mask for the virtual IP address (255.255.255.0) and the preempt option. As in option B, the preempt option allows the router to take over as the master if it has a higher priority than the current master. The track option is also used to adjust the priority based on the status of another object (in this case, object 1). If object 1 goes down, the priority will be decremented by 10, which could cause the router to lose its master status.
In conclusion, the best answer for this scenario is B, standby 5 ip 172.16.13.254 standby 5 priority 100 standby 5 preempt. This command set configures VRRP with group number 5, virtual IP address 172.16.13.254, and priority 100. The preempt option allows the router to take over as the master if it has a higher priority than the current master.
