You have a subscription with an Azure Virtual Desktop host pool (Pool1) whose session hosts are Microsoft Entra joined. A user (User1) must be able to connect to the session hosts from multiple devices. To enable connectivity from all devices while minimizing administrative effort, what should you do?

Adding a custom RDP property to Pool1 is the correct solution because it allows you to configure settings that apply to all session hosts within that host pool, ensuring consistent behavior for all users connecting to Pool1. Specifically, the enablerdsaadauth RDP property, when set to 1, enables Azure Active Directory authentication for RDP connections, which is necessary for Microsoft Entra joined session hosts. This approach minimizes administrative effort as you configure it once at the host pool level rather than on individual session hosts or devices. Configuring Connection information settings from the RDP Properties of Pool1 is not a valid option as it does not exist. Configuring Client Settings from the RDP-Tcp Properties of an individual device (Device1 or Device3) is incorrect because RDP-Tcp properties are server-side settings on the session host, not client-side settings, and configuring them on a single device would not apply to all devices.
