The Radiology group requires that changes on the virtual desktops be retained. Which configuration should the architect specify for the XenDesktop infrastructure?

Provisioning Services with 'cache on server persistent' is a write cache optimization strategy for the PVS server itself and does not retain individual user changes on the virtual desktop.

Provisioning Services with 'cache on server' refers to a general write cache location on the PVS server and does not provide the capability to persist user-specific changes on the virtual desktop.

Personal vDisk (PvD) is a XenDesktop feature that allows user-specific changes, installed applications, and user data to be persisted on a dedicated disk across reboots in a shared-image, non-persistent virtual desktop environment, meeting the requirement to retain changes.

Provisioning Services with 'standard image mode' results in a non-persistent desktop where all user changes are discarded upon reboot, directly contradicting the requirement to retain changes.
