You have been assigned to create a plan to implement HSRP on the router connecting your company's network to the Internet. The router should be the active router in the HSRP group. On the active router, the following conditions should be met:
Enable preemption with no delay
Set Hello timer to 10 seconds and hold time to 25 seconds
Set the priority to 150
Which of the following commands should be included in the plan to meet the given requirements? (Choose all that apply.)

Reference / correct answer:
The following commands should be included in the implementation plan to meet the given requirements:
standby 1 preempt standby 1 priority 150
standby 1 timers 10 25
The standby 1 preempt command configures the preempt settings on the router. This command allows preemption without any delay. The standby 1 priority 150 command sets the priority of the router to 150. The default priority of HSRP routers is 100. This implies that this router becomes the active router if there are no other routers in the group with a higher priority. The standby 1 timers 10 25 command sets the Hello timer and the hold time on the local router. The first value, 10, specifies the Hello timer, and the second value, 25, indicates the hold time.
The most essential steps to configure HSRP on routers are as follows:
Assign IP addresses to the interfaces using the ip address command
Enable HSRP on the interfaces and assign the virtual IP address using the standby ip command
Set the HSRP priority of the interfaces using the standby priority command
Configure HSRP preempt settings on the interfaces using the standby preempt command
Set the Hello timers using the standby timers command
Enable interface tracking for other HSRP-enabled interfaces using the standby track command
The standby 1 preempt delay minimum 10 command should not be included in the implementation plan. This command causes the router to preempt the active router after a minimum of 10 seconds. However, the requirement states that there should be no delay in preemption (a delay of 0 seconds), which is the default behavior.
The standby 1 timers 25 10 command should not be included in the implementation plan. This command sets the Hello timer to 25 seconds and the hold time to 10 seconds. However, the requirement is to set the Hello timer to 10 seconds and the hold time to 25 seconds.
The standby track interface S0/1 command should not be included in the implementation plan. This command enables tracking of the S0/1 interface on the local router. However, there is no requirement in the scenario to track an interface. Tracking can be used to decrement the priority of an HSRP router when the interface goes down. Using the default decrement value, if S0/1 were to go down, the priority of the router would be reduced by 10.
