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.

HSRP (Hot Standby Router Protocol) is a Cisco proprietary protocol that provides redundancy for IP networks, allowing for failover between routers in a group. HSRP group numbers range from 0 to 4095, and each router in the group is assigned a priority value. The router with the highest priority in a group is elected as the active router, and the other routers become standby routers. The active router is responsible for forwarding traffic for the virtual IP address of the group, and the standby routers are ready to take over if the active router fails.
In this scenario, the engineer needs to configure HSRP group 300 on a Cisco IOS router and ensure that the router is the active HSRP router when it becomes functional. The peer router has been configured with the default priority value, which is 100.
Option A: standby version 2 - This command specifies that HSRP version 2 should be used. standby 300 priority 110 - This command sets the priority of the local router to 110, which is higher than the default priority of 100 on the peer router. standby 300 preempt - This command enables preemption, which allows the local router to take over as the active router if its priority becomes higher than the current active router.
Option B: standby 300 priority 110 - This command sets the priority of the local router to 110, which is higher than the default priority of 100 on the peer router. standby 300 timers 1 110 - This command sets the HSRP hello timer to 1 second and the hold timer to 110 seconds.
Option C: standby version 2 - This command specifies that HSRP version 2 should be used. standby 300 priority 90 - This command sets the priority of the local router to 90, which is lower than the default priority of 100 on the peer router. standby 300 preempt - This command enables preemption, which allows the local router to take over as the active router if its priority becomes higher than the current active router.
Option D: standby 300 priority 90 - This command sets the priority of the local router to 90, which is lower than the default priority of 100 on the peer router. standby 300 preempt - This command enables preemption, which allows the local router to take over as the active router if its priority becomes higher than the current active router.
Based on the requirements in the question, Option A is the correct command set. By setting the local router's priority to 110, which is higher than the default priority of 100 on the peer router, the local router will become the active router when it comes online. Additionally, enabling preemption ensures that the local router will remain the active router as long as its priority remains higher than the peer router's priority.
