1Y0-204 App and Desktop Image Management Practice Question
An administrator is using Citrix Provisioning (PVS) to stream a vDisk to 200 target devices. After updating the vDisk to a new version, the administrator notices that some target devices are still booting from the old version. The vDisk is in Standard Image mode. What is the most likely cause?
⚠ Common exam trap
The trap here is thinking that a simple restart or service refresh will cause devices to pick up the new vDisk version, when actually the version must be explicitly promoted.
Answer choices
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
✓
The vDisk version was not promoted to the production version in the PVS console.
In Citrix Provisioning, a vDisk update creates a new version, but target devices only use it after it is promoted to production. The administrator must use the PVS console to promote the version. Without promotion, devices boot from the previous version. Restarting services or devices does not change the assigned version.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
The vDisk version was not promoted to the production version in the PVS console.
Why this is correct
In PVS, after updating a vDisk, you must promote the new version to production. Until promoted, target devices continue to boot from the previous production version. This is a common oversight. The administrator needs to use the PVS console to set the new version as the boot version for the devices.
- ✗
The target devices need to be restarted to clear the ARP cache.
Why it's wrong here
ARP cache is related to network address resolution and does not affect vDisk version selection. Restarting devices may trigger a re-read of the boot configuration, but the root cause is version promotion. Clearing ARP cache would not change the vDisk version the device boots from.
- ✗
The target devices have cached the old vDisk in their local write cache.
Why it's wrong here
In Standard Image mode, target devices do not cache the vDisk locally; they stream it from the PVS server. The write cache stores temporary writes, not the base image. Caching the old vDisk would only occur if the devices were in Private Image mode, which is not the case here.
- ✗
The PVS server's streaming service needs to be restarted to apply the new vDisk version.
Why it's wrong here
Restarting the streaming service is not required to apply a new vDisk version. The service dynamically serves the version specified in the device's boot configuration. The issue is that the new version has not been promoted, so the service continues to serve the old version.
