1Y0-204 Resource Provisioning and Delivery Practice Question
An administrator is configuring a Citrix Provisioning (PVS) environment for a new pooled VDI deployment. The administrator wants to ensure that the vDisk is updated without affecting users currently connected. The vDisk is currently in Private Image mode. Which step must the administrator take to allow multiple users to access the vDisk while still being able to update it later?
⚠ Common exam trap
The trap here is assuming that Private Image mode can be used with write cache to support multiple users, when Private Image mode inherently restricts access to a single device.

Correct answer & explanation
✓
Change the vDisk to Standard Image mode and set it to read-only.
To allow multiple users to access a vDisk concurrently while still being able to update it later, the vDisk must be in Standard Image mode. In this mode, the vDisk is read-only and can be shared by multiple target devices. Updates are performed by switching to Private Image mode or using a maintenance version. This provides the flexibility required by the administrator.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Keep the vDisk in Private Image mode and enable write cache on the target devices.
Why it's wrong here
Private Image mode allows only one target device to access the vDisk at a time, so it cannot support multiple users concurrently. Enabling write cache does not change the access mode; it only affects how writes are handled. This option does not meet the requirement of allowing multiple users to access the vDisk while still being able to update it later.
- ✗
Set the vDisk to Standard Image mode and enable write cache on the Provisioning Server.
Why it's wrong here
Standard Image mode is correct for multi-user access, but enabling write cache on the Provisioning Server is not a valid configuration. Write cache is typically configured on the target device or via a cache file on the server, but the key is that the vDisk in Standard Image mode is read-only. This option incorrectly suggests that write cache on the server is necessary, which is not the case.
- ✓
Change the vDisk to Standard Image mode and set it to read-only.
Why this is correct
In Standard Image mode, the vDisk is read-only and can be shared by multiple target devices simultaneously. This allows multiple users to access the same vDisk while preventing changes from being written back to it. To update the vDisk later, the administrator can switch it to Private Image mode or use a maintenance version, making this the correct choice for the scenario.
- ✗
Convert the vDisk to a differencing disk and assign it to each user.
Why it's wrong here
Differencing disks are used for write cache in PVS, but they are not a vDisk mode. Converting the vDisk to a differencing disk would not allow multiple users to share the same base vDisk. This option misinterprets PVS concepts and does not provide a valid way to share the vDisk while enabling updates.
