1Y0-312 Advanced Provisioning and Image Management Practice Question
An administrator is using Provisioning Services (PVS) to stream a vDisk to 100 target devices. The administrator notices that the write cache is filling up quickly on the target devices, causing performance degradation. The current write cache is configured to be stored in RAM with a maximum size of 2 GB. The administrator wants to change the write cache to be stored on a local disk to improve performance. Which action should the administrator take?
⚠ Common exam trap
The trap here is assuming that write cache is configured on the vDisk or server, when it is actually a target device setting.
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
✓
Edit the target device properties and set the write cache to 'Cache on device hard drive' with a desired size.
Write cache settings in PVS are configured on target devices or device collections. To change the write cache from RAM to local disk, the administrator must modify the target device properties and select 'Cache on device hard drive'. This offloads writes to the local disk, reducing RAM usage and improving performance.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Recreate the vDisk in Private Image mode and enable local write cache.
Why it's wrong here
Recreating the vDisk in Private Image mode would make it unsuitable for multiple target devices and does not directly configure write cache location. Private Image mode is for single-device use, so this would not solve the performance issue for 100 devices.
- ✗
Use the PVS Console to change the server-side write cache to disk.
Why it's wrong here
Server-side write cache is a different setting and is not configured via the PVS Console in this manner. The requirement is to change the write cache on the target devices, not on the server. This option misinterprets the write cache architecture.
- ✗
Modify the vDisk properties and change the write cache type to 'Cache on device hard drive'.
Why it's wrong here
The write cache type is not configured in the vDisk properties. It is set on the target device or via a device collection setting. Changing vDisk properties does not affect write cache location, so this action would not resolve the issue.
- ✓
Edit the target device properties and set the write cache to 'Cache on device hard drive' with a desired size.
Why this is correct
Write cache settings are configured per target device or via a device collection. Changing the target device properties to use 'Cache on device hard drive' and specifying a size will offload the write cache to local disk, improving performance and preventing RAM exhaustion.
