1Y0-204 App and Desktop Image Management Practice Question
An administrator wants to use PVS to deploy a new application. What is the standard workflow for updating the vDisk?
⚠ Common exam trap
Candidates frequently attempt to apply updates directly to a vDisk while it remains in Standard mode, forgetting that write operations are blocked.

Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Set vDisk to Private Image mode, apply changes, then revert to Standard mode.
The PVS update process involves putting the vDisk into 'Private Image' mode, applying changes, and then promoting it back to 'Standard' mode. This staged approach is critical for maintaining high availability. By testing the updated vDisk in a controlled manner before rolling it out to all production target devices, administrators minimize the risk of deployment errors and ensure that the new application is fully functional across the entire user base.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Update the master image, then reboot all target devices simultaneously.
Why it's wrong here
Rebooting all devices at once causes a 'boot storm' that can overwhelm the network and the PVS servers. A phased update strategy is always recommended to ensure that the environment remains stable and that any issues found in the updated image do not affect every user at once.
- ✓
Set vDisk to Private Image mode, apply changes, then revert to Standard mode.
Why this is correct
Private Image mode allows an administrator to boot a single target device in read-write mode to make changes, such as installing applications. After the changes are verified, the disk is returned to Standard mode for read-only streaming to the broader production environment, ensuring consistent image delivery.
- ✗
Copy the vDisk to each target device's local drive and update it.
Why it's wrong here
PVS is designed for centralized management. Copying vDisks to local drives defeats the purpose of image streaming. It introduces complexity, makes patching difficult, and negates the benefits of having a single 'gold' image that can be updated once and deployed to thousands of machines.
- ✗
Create a new MCS catalog using the updated PVS image.
Why it's wrong here
MCS and PVS are two distinct provisioning technologies. You cannot use a PVS vDisk as the source for an MCS machine catalog. Mixing these technologies is unsupported and conceptually incorrect, as they use different methods for delivering virtual desktops and maintaining machine state.
