Citrix Virtual Apps and Desktops 7 Advanced Administration — Question 18

Scenario: A Citrix Engineer is managing a Provisioning Services environment. The day after a new vDisk version is rolled out to production, multiple users report issues with one of the core applications hosted on the vDisk image. The administrator wants to roll back the new change and allow the target devices to stream from a functioning vDisk as soon as possible.
How can the engineer accomplish this in the least amount of time?

Answer options

• A. Perform a vDisk merge to consolidated differencing disk, then restart the target devices.
• B. Copy an older version of the vDisk from the backup storage location, then reassign all the target devices to the imported vDisk and restart them.
• C. Revert the vDisk version to Maintenance or Test mode, then restart the target devices.
• D. Create a new version of the vDisk and reinstall the application, then restart the target devices.

Correct answer: C

Explanation

The correct answer is C because reverting the vDisk to Maintenance or Test mode allows the target devices to quickly revert to a previous stable state without the need to copy or merge disks. Options A, B, and D involve more time-consuming processes that would delay the restoration of service for the users experiencing issues.
