What alarm action should an administrator use to run a batch file on a specific VM?

To run a batch file on a specific virtual machine in response to an alarm, the action to use is to run a script. This capability allows the administrator to automate tasks such as adjustments, notifications, or recovery processes by triggering a specific script housed on the virtual machine or within the environment.

Using the 'Run script' action enables the execution of command-line scripts that can perform a variety of tasks, including running batch files that execute multiple commands or scripts on the VM itself. This is crucial for automated responses to events monitored by alarms, allowing proactive management of the virtual environment.

Other options like sending SNMP traps, running PowerCLI commands, or sending email notifications do not directly execute a batch file on the VM. Instead, they serve different purposes—such as notifying administrators, integrating with network management systems, or providing information about the state of the VM, but they won't perform actions directly on the VM itself.
