1Y0-312 Advanced Provisioning and Image Management Practice Question
An administrator is managing a Citrix Provisioning (PVS) environment. The administrator needs to update a vDisk that is currently in Standard Image mode and in use by multiple target devices. The update should not disrupt the running devices, and the administrator wants to be able to roll back if issues arise. Which action should the administrator take?
⚠ Common exam trap
The trap here is thinking that the vDisk must be taken offline to update it, but versioning allows updates to a new version while the current version remains in use.

Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Create a new version of the vDisk, apply updates to the new version, and then promote it.
Creating a new version of the vDisk is the correct approach for updating a Standard Image vDisk without disrupting running devices. The new version can be updated offline, then promoted to become the boot version. The previous version remains available for rollback. Other methods either disrupt service or are not applicable to Standard Image mode.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Set the vDisk to Private Image mode, apply updates, then revert to Standard Image mode.
Why it's wrong here
Changing to Private Image mode while devices are running is not possible because the vDisk is in use. Private Image mode is for single-device access, so it would disrupt the running devices. This approach is not suitable for updating a vDisk in use by multiple devices without downtime.
- ✗
Use the 'Merge' function to combine changes from a differencing disk into the base vDisk.
Why it's wrong here
The Merge function is used to merge changes from a Private Image vDisk into a new Standard Image version. It is not used to update a vDisk that is already in Standard Image mode and in use. Merging would require the vDisk to be in Private Image mode and offline.
- ✓
Create a new version of the vDisk, apply updates to the new version, and then promote it.
Why this is correct
Creating a new version allows updates to be applied without affecting the current version in use. Once the new version is ready, promoting it makes it the boot version for devices on next reboot. This method provides rollback capability because the previous version remains available.
- ✗
Update the master image directly on the provisioning server and restart the Stream Service.
Why it's wrong here
Updating the master image directly would affect all devices using the vDisk immediately and could cause inconsistencies or failures. Restarting the Stream Service would interrupt streaming to all devices. This method does not provide a controlled update or rollback option.
