To make this router the active HSRP for group 300 when the peer uses the default priority, which command set is required?

The correct answer ensures the router becomes the active HSRP device. standby version 2 enables HSRPv2, which is recommended for modern deployments and supports a wider range of group numbers. standby 300 priority 110 sets the HSRP priority to 110. Since the default HSRP priority is 100, a priority of 110 is higher, making this router preferred. standby 300 preempt allows the router with the higher priority to immediately take over as the active router if it comes online or if a higher-priority router becomes available. Without preempt, a router with a higher priority would not become active unless the current active router failed. The incorrect options either use a priority that is not higher than the default (90), omit preempt, or include unnecessary timers configuration which is not required to achieve active status when the peer uses default priority.
