Which statement best describes the action of the differencing disk for non-persistent desktops after a restart in a virtualized environment?

• A. It will be updated from the base image.
• B. It will be synchronized with the attached Personal vDisk.
• C. It will be disconnected and recreated.
• D. It will be merged with the base image.

Answer: (C)

In non-persistent desktops, user changes during a session are written to a separate cache disk (the differencing disk) rather than the base image. The design goal is to revert the VM to a pristine state after each restart. So when the desktop restarts, that current differencing disk is effectively discarded and a new one is created for the next session. The base image stays the same, and nothing is merged back into it. This is why the action described—disconnecting the existing differencing disk and creating a fresh one on the next boot—best fits the behavior. It’s not updating the base image, not syncing with a Personal vDisk, and not merging changes into the base image, all of which would imply persistence of changes rather than a reset to the original image.
