AZ-140 Exam Preparation Material | Configuring and Operating Microsoft Azure Virtual Desktop

Explanation:
Azure Advisor is a personalized cloud consultant that helps you follow best practices to optimize your Azure deployments. When it recommends enabling a validation environment for Azure Virtual Desktop (AVD), it's referring to setting up an environment where you can test out new features, updates, or changes before rolling them out to your production environment.
The option that best matches the description of ensuring business continuity through AVD service deployments by enabling a validation environment would be:
C. Preview features for Azure Virtual Desktop
This is because a validation environment is commonly used to assess new features or updates in a non-production environment to ensure that they do not disrupt the service when implemented in production. This helps maintain business continuity by preventing untested changes from affecting end-users. It's not specifically for testing capacity, security settings, or Azure Site Recovery failover, although those could also benefit indirectly from having a validation environment.

Explanation:
To ensure that User1 can create RemoteApp app groups that will be used to stream a suite of custom apps from the host pools, while adhering to the principle of least privilege and minimizing administrative effort, the following should be considered:
Role: User1 needs to have the ability to create and manage app groups. The "Desktop Virtualization Application Group Contributor" role would allow User1 to create and manage application groups within Azure Virtual Desktop. This role is specific enough to adhere to the principle of least privilege while allowing User1 to perform the necessary tasks.
Number of app groups: Since the apps must be available to users in all pools, and to minimize administrative effort, User1 should create a single app group that contains the suite of custom apps. This app group can then be associated with each host pool. This way, there is only one set of apps to manage across all host pools, which simplifies administration.
Therefore, the correct answers are:
Role: Desktop Virtualization Application Group Contributor
Number of app groups: 1
