1Y0-204 App and Desktop Image Management Practice Question
An administrator is using MCS and observes that the 'Write Cache' disk is filling up rapidly. What should the administrator do to mitigate this?
⚠ Common exam trap
Candidates often suggest deleting the VM or recreating the catalog, which is unnecessary and destructive. The fix is simply adjusting the size property within the existing catalog configuration.
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
✓
Increase the write cache disk size in the catalog properties.
The write cache disk stores all changes made to a non-persistent virtual machine during a session. If it fills up, the machine will crash or stop responding. Increasing the size of the write cache disk or redirecting temporary data (like browser caches or print spoolers) to a persistent location is the correct way to ensure session stability and prevent the machine from becoming unusable due to disk space exhaustion.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Increase the size of the master image disk.
Why it's wrong here
Increasing the master image size does not affect the write cache disk. The write cache is a separate, ephemeral disk that stores session-specific changes. Modifying the gold image does not change the disk allocation logic for the write cache of already provisioned virtual machines.
- ✓
Increase the write cache disk size in the catalog properties.
Why this is correct
Adjusting the write cache size in the machine catalog properties is the standard administrative action to provide more space for delta changes. This is necessary for applications that generate high volumes of temp data, ensuring that user sessions do not fail during normal operations.
- ✗
Reboot the virtual machines to clear the cache.
Why it's wrong here
Rebooting the machines clears the cache, but it does not fix the underlying problem of the cache filling up during a single session. If the cache is too small for the user's workload, it will simply fill up again after the reboot, causing repeated session failures.
- ✗
Decrease the memory allocation to the virtual machine.
Why it's wrong here
Decreasing memory will likely cause the OS to swap more frequently to the disk, which would actually increase the amount of data written to the cache disk. This would exacerbate the problem of the cache disk filling up rather than resolving it.
