Question

A Citrix Engineer must change the write cache method from 'Cache on device hard drive' to 'Cache in device RAM with overflow on hard disk'. To assist in determining the appropriate amount of RAM cache required, what would the engineer need to check to determine the current write cache size?

Options

  • AThe size of the local pagefile
  • BThe size of the writecache file in the vDisk store
  • CThe size of the .vdiskcache file on the device hard disk
  • DThe size of the RAM and Pagefile combined in Task Manager

Why each option

This question tests knowledge of how to determine the existing write cache size before switching the Citrix Provisioning Services write cache method to RAM with overflow.

AThe size of the local pagefile

The local pagefile is a Windows virtual memory file and is not related to the Provisioning Services write cache size.

BThe size of the writecache file in the vDisk store

The writecache file in the vDisk store relates to server-side cache, not the device-side hard drive cache used by the 'Cache on device hard drive' method.

CThe size of the .vdiskcache file on the device hard diskCorrect

When the write cache method is set to 'Cache on device hard drive', Provisioning Services creates a .vdiskcache file on the target device's local hard disk. Checking the size of this file reveals how much write cache space is currently being consumed, which directly informs how much RAM cache to allocate for the new method.

DThe size of the RAM and Pagefile combined in Task Manager

The combined RAM and pagefile size in Task Manager reflects overall system memory usage, not the specific write cache consumption tracked by Provisioning Services.
