1Y0-204 App and Desktop Image Management Practice Question
An administrator is using Citrix Provisioning (PVS) to stream a vDisk to 50 target devices in a Citrix Virtual Apps and Desktops 7 environment. The administrator needs to update the vDisk with a new application but must ensure that users can continue to work during the update process. What should the administrator do?
⚠ Common exam trap
The trap here is thinking that vDisks can be updated in place while in Standard Image mode, or that downtime is required, when versioning is the designed non-disruptive method.
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
✓
Create a new version of the vDisk, apply the update to the new version, and then promote it to production.
The correct method is to create a new version of the vDisk, apply the update to that version, and then promote it to production. This allows the current version to remain in use while the new version is prepared, and target devices can be rebooted at a convenient time to switch to the new version, minimizing disruption.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Use the PVS console to update the vDisk in Standard Image mode while target devices are running.
Why it's wrong here
In Standard Image mode, the vDisk is read-only for target devices, and updates cannot be written directly to it while devices are streaming from it. Attempting to update it while in use would fail or require taking it offline, which disrupts users. The correct method involves versioning.
- ✓
Create a new version of the vDisk, apply the update to the new version, and then promote it to production.
Why this is correct
PVS supports versioning of vDisks. Creating a new version allows the administrator to update the vDisk without affecting the current version in use. Once the new version is ready, it can be promoted, and target devices can be rebooted to pick up the new version. This enables updates with minimal disruption.
- ✗
Shut down all target devices, update the vDisk, and then restart the devices.
Why it's wrong here
Shutting down all target devices causes downtime for all users, which violates the requirement to allow users to continue working during the update. This method is disruptive and does not leverage PVS's versioning capabilities to minimize impact.
- ✗
Set the vDisk to Private Image mode, update it, then set it back to Standard Image mode and restart the target devices.
Why it's wrong here
Switching to Private Image mode allows a single device to write to the vDisk, but it requires taking the vDisk offline for all other devices, causing downtime. This approach is not suitable for keeping users productive during the update, as it disrupts the streaming service for all other target devices.
