You have subscription Sub1 and user Admin1 assigned the Desktop Virtualization Contributor role for Sub1. You need to ensure Admin1 can assign Scaling1 to Pool1. Solution: Assign the Azure Virtual Desktop service principal the User Access Administrator role for Sub1. Does this meet the goal?

The solution does not meet the goal. While the Desktop Virtualization Contributor role on Sub1 allows Admin1 to manage most aspects of Azure Virtual Desktop deployments, it does not inherently grant permission to assign scaling plans to host pools. Assigning the Azure Virtual Desktop service principal the User Access Administrator role for Sub1 is incorrect and unnecessary for this specific task. The User Access Administrator role is used to manage user access to Azure resources, not to enable a user to assign scaling plans. To allow Admin1 to assign Scaling1 to Pool1, Admin1 needs specific permissions related to scaling plans and host pools, which are typically covered by the Desktop Virtualization Contributor role at the resource group level where the host pool and scaling plan reside, or by a custom role with the necessary actions.
