1Y0-204 App and Desktop Image Management Practice Question
An administrator is using Citrix Provisioning (PVS) to provision target devices in a Citrix Virtual Apps and Desktops 7 environment. The administrator needs to update a vDisk with a new version of an application. Which two actions must the administrator perform to ensure a successful vDisk update? (Choose two.)
⚠ Common exam trap
The trap here is thinking that vDisks are updated by copying files or using the Imaging Wizard, rather than modifying the vDisk in Private Image mode.

Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Set the vDisk to Private Image mode before making changes.
To update a PVS vDisk, the administrator must first set it to Private Image mode, which allows a single target device to write changes directly to the vDisk. Then, boot a target device from that vDisk and apply the application update. After completion, revert to Standard Image mode for production use.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Configure a write cache disk on the provisioning server to store updates.
Why it's wrong here
Write cache is used on target devices to store temporary writes in Standard Image mode, not on the provisioning server. The provisioning server streams the vDisk, but updates are made directly to the vDisk in Private Image mode. Configuring a write cache on the server is not part of the update process and would not persist changes to the vDisk. Thus, this action is incorrect.
- ✓
Set the vDisk to Private Image mode before making changes.
Why this is correct
To update a vDisk, it must be in Private Image mode, which allows a single target device to boot from and write to the vDisk. This mode enables the administrator to make changes that persist. After updating, the vDisk is typically set back to Standard Image mode for multiple devices to share it. This is a required step for updating a vDisk.
- ✗
Run the Citrix Provisioning Imaging Wizard to capture a new vDisk.
Why it's wrong here
The Imaging Wizard is used to create a new vDisk from a master device, not to update an existing vDisk. For updates, the administrator should use Private Image mode and boot a target device to apply changes. Running the Imaging Wizard would create a separate vDisk, which is not the desired outcome. Therefore, this is not a required action for updating a vDisk.
- ✓
Boot a target device from the vDisk and apply the application update.
Why this is correct
Once the vDisk is in Private Image mode, the administrator must boot a target device from that vDisk to install or update the application. The changes are written directly to the vDisk. After the update, the target device is shut down, and the vDisk is set back to Standard Image mode. This action is essential for applying updates to the vDisk.
- ✗
Use the Citrix Provisioning console to copy the vDisk to all target devices.
Why it's wrong here
In PVS, target devices do not store a copy of the vDisk; they stream it from the provisioning server. The vDisk is shared, so copying it to each device is not part of the update process. The console is used to manage vDisks, but not to push copies to devices. This action is unnecessary and incorrect for updating a vDisk.
