1Y0-204 App and Desktop Image Management Practice Question
When using MCS, what happens to the data stored on the temporary write cache disk when a user logs off a non-persistent desktop?
⚠ Common exam trap
Candidates often confuse non-persistent environments with persistent ones, incorrectly assuming that user data or changes made to the temporary write cache disk are retained across user logoffs and reboots.

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
✓
It is permanently deleted/discarded.
In non-persistent environments, the write cache disk is discarded or reset upon logoff or reboot. This is the core principle of non-persistent desktops: the environment is returned to its original, pristine state after every use. This approach ensures that any malicious activity or system changes made during a session are wiped, enhancing security and preventing the accumulation of 'bit rot' that degrades desktop performance over time.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
It is archived to a long-term storage location.
Why it's wrong here
The write cache disk is ephemeral and not intended for long-term storage. Archiving this data would be prohibitively expensive and technically complex, as the write cache is intended to be discarded to ensure the desktop returns to its base state after the user session ends.
- ✓
It is permanently deleted/discarded.
Why this is correct
The write cache disk is treated as temporary storage in non-persistent pools. Upon logoff or reboot, the disk is wiped or replaced with a blank version, ensuring that the machine is refreshed and any temporary files or changes are removed, maintaining the image's integrity.
- ✗
It is merged back into the master image.
Why it's wrong here
Merging user data back into the master image is not how MCS functions and would be a security risk. The master image should remain immutable. Changes made by users are kept separate so they do not affect other users or permanently alter the base gold image.
- ✗
It is moved to the user's personal profile folder.
Why it's wrong here
The write cache disk is an OS-level temporary disk and is not the same as a user profile. User profile data is managed by separate solutions like Citrix Profile Management. Moving the cache disk content to a profile folder is not a supported or functional operation.
