   A network engineer is troubleshooting a VRRP issue on OS10. The 'show vrrp' command shows the group is in 'Backup' state, but the switch is not receiving advertisements from the master. What should the engineer check first?

   • AVerify that preempt is enabled on the backup switch.
   • BVerify that the interface is up and that the VRRP group is enabled on the interface.
   • CCheck the virtual IP configuration on the backup switch.
   • DCheck the priority of the backup switch.

   A network engineer is configuring VRRP on OS10 for a VLAN. They want to ensure that a specific switch becomes master only when its uplink to the core is operational. They configure object tracking on the switch to decrement priority by 20 when the uplink goes down. The switch has a priority of 110, and the backup switch has a priority of 100. What will happen when the uplink goes down?

   • AThe switch will become backup, and the backup switch will become master.
   • BThe switch will remain master because its priority (90) is still higher than the backup's priority (100)?
   • CThe switch will remain master because preempt is enabled on it.
   • DThe VRRP group will go into an error state.

   Two OS10 switches run VRRP for a gateway. The network team is concerned about failover time. They currently have an advertisement interval of 1 second and a master down timer of 3 seconds. They want to reduce failover time to under 1 second. Which configuration change will achieve this?

   • AChange the virtual IP to a different subnet.
   • BDisable preempt on the master switch.
   • CSet the advertisement interval to 200 milliseconds, which will set the master down timer to approximately 600 milliseconds.
   • DIncrease the priority of the backup switch to 150.

   An administrator is troubleshooting a VRRP issue on OS10. The 'show vrrp' command shows the group in 'Master' state on both switches. What is the most likely cause of this split-brain condition?

   • AThe priority is set to 255 on both switches.
   • BThe switches are not receiving VRRP advertisements from each other due to a Layer 2 connectivity issue.
   • CThe virtual IP is configured differently on the two switches.
   • DThe advertisement interval is set to 0 on both switches.
