1Y0-312 Advanced Provisioning and Image Management Practice Question
An administrator is managing a Citrix Provisioning (PVS) environment with a vDisk in Standard Image mode. The vDisk is configured with a write cache type of 'Cache on server'. Users report that after a recent update to the vDisk, some target devices experience slow logons and high disk latency. The administrator notices that the write cache file is stored on the same volume as the vDisk. Which action should the administrator take to improve performance?
⚠ Common exam trap
The trap here is assuming that increasing RAM or changing the cache type is the solution, but the specific issue is I/O contention due to co-locating the write cache file and vDisk on the same volume.
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
✓
Move the write cache file to a separate volume with higher performance.
The correct answer is to move the write cache file to a separate volume with higher performance. When using 'Cache on server', the write cache file is stored on the PVS server. If it shares a volume with the vDisk, I/O contention occurs, causing latency. Separating them onto different volumes, preferably SSDs, resolves the contention. Other options do not directly address the root cause.
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 amount of RAM on the PVS servers.
Why it's wrong here
Adding RAM to the PVS servers might help with caching but does not directly address the disk I/O contention caused by the write cache file and vDisk being on the same volume. The bottleneck is disk I/O, not memory. While more RAM can improve overall performance, it is not the targeted solution for this specific issue.
- ✓
Move the write cache file to a separate volume with higher performance.
Why this is correct
When using 'Cache on server' write cache type, the write cache file is stored on the PVS server. If it resides on the same volume as the vDisk, it can cause I/O contention, leading to high latency and slow logons. Moving the write cache file to a separate, high-performance volume (e.g., SSD) alleviates this contention and improves performance. This is a recommended best practice for PVS.
- ✗
Enable write cache on the target device's local disk.
Why it's wrong here
Enabling write cache on the target device's local disk would change the write cache type to 'Cache on device hard disk' or similar, which may not be desirable in all scenarios. It also requires local disk space and may not be as fast as a dedicated server-side volume. The issue is server-side contention, so moving the cache on the server is more appropriate.
- ✗
Change the write cache type to 'Cache in device RAM with overflow on hard disk'.
Why it's wrong here
Changing to RAM-based cache with overflow might improve performance, but it requires sufficient RAM on the target devices and can introduce complexity. The scenario specifically points to the write cache file being on the same volume as the vDisk, causing contention. Moving the cache to a different volume is a more direct solution. RAM-based cache is not always feasible due to memory constraints.
