An engineer must configure a Nexus 7000 series switch for HSRP on VLAN 100. When fully functional, the router must be the active master. Which set of commands must be used to implement the scenario?

Option A contains the correct sequence of commands for HSRP configuration: specifying the VLAN interface, assigning an IP address, defining the HSRP group, setting a virtual IP, configuring a higher priority (e.g., 150) to make it active, and enabling preemption to allow it to take over as master.

Option B likely omits or incorrectly configures essential HSRP parameters such as the priority, preempt command, or virtual IP address, preventing the router from becoming the active master.

Option C probably contains syntax errors, missing commands, or incorrect values for the HSRP group, IP addresses, or priority settings, which would lead to an inactive or incorrect HSRP state.

Option D fails to include the necessary commands to establish the router as the active HSRP master, possibly lacking the `priority` and `preempt` commands that dictate master election.
