To reduce the total number of writes on storage with minimal administrative effort when there are multiple storage locations, which option should you implement?

• A. Citrix Provisioning
• B. Machine Creation Services input/output optimization
• C. Personal vDisk
• D. Storage Area Network (SAN)

Answer: (B)

To minimize the total writes to storage across multiple locations with minimal administrative effort, enable Input/Output optimization for Machine Creation Services. This feature caches I/O at the MCS layer, reducing the amount of data written to the shared back-end storage by absorbing writes and frequently accessed reads locally on the MCS host. Because it adjusts how the existing MCS workflow handles I/O rather than rearchitecting the whole provisioning approach, it lowers storage write activity with only a simple enablement change.

Other options would either introduce more complexity or focus on different approaches: Citrix Provisioning streams vDisks and relies on a separate streaming infrastructure with its own caching strategy, Personal vDisk adds per-user writable data that increases writes rather than reduces them, and a SAN is a hardware solution that doesn’t inherently reduce I/O across multiple locations or minimize administrative effort.
