What tool should you use to manage session timeout properties for session hosts in an Azure Virtual Desktop environment?

To manage session timeout properties for session hosts in an Azure Virtual Desktop environment, the Local Group Policy Editor is the appropriate tool to use. This tool allows administrators to configure various local policies, including session timeout settings, which control how long a user's session can remain idle before it is automatically disconnected or logged off.

In Azure Virtual Desktop, session hosts are typically Windows machines where user sessions are established. The Local Group Policy Editor enables granular control over session behaviors, providing the ability to set policies that determine session limits and disconnection behaviors. By adjusting these policies, administrators can enhance resource management and improve user experience by ensuring that inactive sessions do not consume valuable resources unnecessarily.

Other tools listed, while useful in their own right, do not specifically manage session timeout properties for individual session hosts directly. The Azure Portal is more focused on broad configuration and monitoring of Azure services rather than fine-grained local policy settings. FSLogix Management Console is primarily designed for managing user profile containers and does not deal with session timeout configurations. The Account Management Interface typically handles user account settings and permissions, rather than session management policies.

Therefore, leveraging the Local Group Policy Editor for setting session timeout properties is the most effective approach within the Azure Virtual Desktop environment.
