Which of the following is a prerequisite for setting up an Azure Virtual Desktop environment?

To establish an Azure Virtual Desktop environment, having an Azure subscription is a fundamental requirement. An Azure subscription provides the necessary resources and services to create and manage virtual desktops and associated components. It serves as the primary framework through which you can access Azure services, including compute, storage, and networking resources required for virtual desktop infrastructure.

Without an Azure subscription, you cannot deploy virtual machines, set up networking, or leverage other Azure capabilities needed to create a functional Azure Virtual Desktop environment. It is the foundational step that grants you access to all other features and resources that Azure provides.

Other options mentioned, like a dedicated physical server, a local database for user management, or specific third-party software installations, are not prerequisites for setting up Azure Virtual Desktop. The architecture of Azure Virtual Desktop is cloud-based, which means it utilizes Azure's infrastructure rather than relying on local physical servers or on-premises databases. Additionally, while certain management tools or software might be beneficial, they are not essential for the initial setup of the Azure Virtual Desktop itself.
