1Y0-312 Advanced Provisioning and Image Management Practice Question
An administrator is using Machine Creation Services (MCS) to provision a catalog of non-persistent machines in Citrix Virtual Apps and Desktops. The administrator needs to update the master image with a new application and roll it out to all machines in the catalog. Which action should the administrator take?
⚠ Common exam trap
It's easy for candidates to confuse MCS with PVS and selecting a PVS-specific tool or cmdlet for an MCS environment.

Correct answer & explanation
✓
Update the master image, then use the Citrix Studio console to update the catalog to use the new image.
For MCS-provisioned catalogs, the standard method to roll out a new master image is to update the master image and then use Citrix Studio to update the catalog. This process creates new identity disks for each machine based on the updated image, while optionally preserving user personalization. It is automated and does not require manual recreation of machines.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Update the master image, then manually delete and recreate each machine in the catalog to pick up the new image.
Why it's wrong here
Manually deleting and recreating each machine is inefficient and unnecessary. MCS provides a built-in update mechanism that automates the process. Manually recreating machines would cause downtime and could lose user personalization if not handled carefully. The correct approach is to use the catalog update feature in Citrix Studio.
- ✗
Update the master image, then use Provisioning Services to update the vDisk and reboot the target devices.
Why it's wrong here
Provisioning Services is a different provisioning technology than MCS. This environment uses MCS, so PVS tools and vDisks are not involved. Using PVS to update the image would not work because the machines are not provisioned by PVS. The administrator must use the MCS-specific update process within Citrix Studio.
- ✗
Update the master image, then use the PowerShell cmdlet Update-ProvScheme to apply the new image to the catalog.
Why it's wrong here
Update-ProvScheme is a PowerShell cmdlet used with Citrix Provisioning (PVS) to update the provisioning scheme, not with MCS. MCS uses different cmdlets, such as Update-BrokerCatalog or the Citrix Studio interface. In this scenario, the environment is MCS-based, so the correct method is through Citrix Studio or MCS-specific PowerShell cmdlets.
- ✓
Update the master image, then use the Citrix Studio console to update the catalog to use the new image.
Why this is correct
In MCS, updating the master image and then using Citrix Studio to update the catalog is the correct procedure. The administrator can either update the existing master image and then trigger an update, or create a new master image and change the catalog to use it. Citrix Studio provides a wizard to roll out the new image, which updates all existing machines in the catalog by creating new identity disks while preserving user data if configured.
