1Y0-204 Resource Provisioning and Delivery Practice Question
An administrator has deployed a pool of virtual machines using Provisioning Services (PVS). What is the primary advantage of using a vDisk in standard mode compared to private mode?
⚠ Common exam trap
Candidates often confuse standard mode with private mode benefits, incorrectly suggesting that standard mode allows persistent user changes, which is the exact opposite of its design.

Correct answer & explanation
✓
It allows for centralized management and deployment of updates to multiple machines simultaneously.
Standard mode allows multiple target devices to share a single read-only vDisk file, which significantly simplifies image management and patching. Any changes made by users are discarded upon reboot, preventing image bloat and ensuring consistency across the fleet. This mode is the standard for non-persistent VDI environments, allowing admins to update a single disk file to refresh hundreds of virtual machines, which is highly efficient for maintenance and administrative lifecycle tasks.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
It provides each user with a unique, persistent operating system environment.
Why it's wrong here
Standard mode is specifically designed for non-persistent environments where the OS disk is shared and read-only. Private mode is the one that allows for persistence, as it grants each target device exclusive access to a writeable vDisk. Standard mode is meant for consistency, not for unique per-user persistence.
- ✓
It allows for centralized management and deployment of updates to multiple machines simultaneously.
Why this is correct
Standard mode enables multiple machines to stream a single read-only vDisk. When an update is needed, the administrator updates the single vDisk file. All machines streaming that disk will then boot into the updated image upon their next restart, making it ideal for streamlined enterprise-wide image maintenance and deployment.
- ✗
It enables the use of local hard drives on the target device for long-term data storage.
Why it's wrong here
Standard mode does not inherently facilitate local long-term storage; it actually focuses on preventing writes to the system disk. Any data written to the local cache is temporary. Long-term data storage should be directed toward network shares, profile servers, or persistent user drives, regardless of the vDisk mode.
- ✗
It provides better performance by caching the entire operating system in the server's RAM.
Why it's wrong here
While PVS can cache parts of the vDisk in server memory, this is a feature of the vDisk/Store configuration, not a specific advantage exclusive to standard mode over private mode. Performance benefits in standard mode primarily stem from the shared nature of the disk and the reduced storage footprint.
