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 appropriate action is to select the option that allows for executing scripts. By choosing to "Run script," the administrator can specify a batch file designed to perform automated tasks, which can include maintenance, backup, or notification processes specific to that VM.

This action enables flexibility in responding to events or conditions as defined by the alarm. In contrast, other options, such as sending SNMP traps or sending email notifications, do not provide the capability to execute scripts directly on the virtual machine. While running a PowerCLI command can allow for remote management tasks via scripts, it does not specifically address the requirement of executing a batch file directly on a VM. Therefore, the option to "Run script" is the most direct and effective method to achieve the desired outcome of executing a batch file.
