Implementing and Operating Cisco Enterprise Network Core Technologies (ENCOR) — Question 272

An engineer must configure HSRP group 300 on a Cisco IOS router. When the router is functional, it must be the active HSRP router. The peer router has been configured using the default priority value. Which command set is required?

Answer options

• A. standby version 2 standby 300 priority 110 standby 300 preempt
• B. standby 300 priority 110 standby 300 timers 1 110
• C. standby version 2 standby 300 priority 90 standby 300 preempt
• D. standby 300 priority 90 standby 300 preempt

Correct answer: A

Explanation

The correct answer is A because it sets the priority to 110, ensuring that this router becomes the active HSRP router, and includes the preempt command to allow it to take over if it becomes available again. Options B and D do not provide the necessary priority to be active, and C incorrectly sets the priority to 90, which is lower than the default priority of the peer router.
