A technician logs into a virtual machine and makes several changes, including IP address configuration and printer driver installation. Which of the following should the technician have performed BEFO

Exporting a VM creates a portable copy but is a time-consuming operation and not intended for quick rollback of in-place changes.

Saving a VM as a complete file is vague and not the standard, explicit method for creating a reversible point in time like a snapshot.

A snapshot captures the state and data of a virtual machine at a specific point in time, allowing for quick rollback if the subsequent changes cause issues. This is a standard practice for non-destructive testing or temporary changes on a VM.

A full system image backup is a comprehensive data recovery solution, but it is more resource-intensive and slower to restore than a VM snapshot for immediate rollback.
