A Citrix Administrator creates a backup schedule that will back up all of the available vDisks. Which three critical file types must to be added to the backup schedule? (Choose three.)

BAK is not a standard file extension used by Citrix Provisioning Services for any vDisk component and is not part of the required vDisk backup file set.

The PVP (Provisioning Services Properties) file stores the vDisk configuration metadata including mode and version settings, and must be backed up to restore the vDisk with its correct operational properties.

The VHD file is the base virtual hard disk image containing the operating system and applications, making it the primary vDisk component required for any successful restore operation.

LOK files are temporary lock files created by PVS while a vDisk is actively in use by a target device and are transient - they are not needed for restoration and should be excluded from backups.

The AVHD file is the differencing disk that captures incremental changes layered on the base VHD in versioned mode, and must be included in backups to preserve all vDisk versions created after the base image.
