1Y0-204 App and Desktop Image Management Practice Question
An administrator is using Citrix Provisioning (PVS) to stream a vDisk to target devices. The vDisk is in Private Image mode for maintenance. After making changes, the administrator switches the vDisk to Standard Image mode and promotes the new version. However, some target devices fail to boot and display a 'Bootstrap' error. What is the most likely cause?
⚠ Common exam trap
The trap here is assuming that promoting the vDisk version automatically updates all target devices, when in fact each device may have its own boot version setting.
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 target devices are configured to boot from a different vDisk version than the one promoted.
A bootstrap error in PVS often occurs when a target device tries to boot from a vDisk version that is not available or not the promoted version. After promoting a new version, devices must be updated to use it. If some devices still reference an old version, they fail to boot. Checking and updating device boot configurations resolves the issue.
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 is still assigned to the target devices in Private Image mode.
Why it's wrong here
If the vDisk were still in Private Image mode, the devices would boot but not share the image. The error indicates a boot failure, not a mode mismatch. Private Image mode assignment would not cause a bootstrap error; it would just prevent multiple devices from using the same vDisk simultaneously.
- ✓
The target devices are configured to boot from a different vDisk version than the one promoted.
Why this is correct
In PVS, each target device has a boot configuration that specifies which vDisk version to use. If a device is set to boot from an older version that is no longer available or not the promoted version, it can fail with a bootstrap error. The administrator must ensure all devices are set to boot from the production version.
- ✗
The target devices' write cache disk is full.
Why it's wrong here
A full write cache disk would cause performance issues or errors, but not a bootstrap error. Bootstrap errors typically occur before the OS loads, during the network boot process. Write cache is used after the OS starts, so it is not the cause of a bootstrap failure.
- ✗
The target devices' boot order is set to network boot, but the PVS server is not responding.
Why it's wrong here
If the PVS server were not responding, no devices would boot, not just some. The issue is intermittent, affecting only some devices, which suggests a configuration difference. A non-responding server would cause all devices to fail with a bootstrap error.
