Subscription Sub1 contains VNet1 and a host pool Pool1 with session hosts connected to VNet1. To add a private endpoint connection to Pool1, what should you do first?

To add a private endpoint connection to an Azure Virtual Desktop (AVD) host pool, the Microsoft.DesktopVirtualization resource provider must be reregistered on the subscription. This action ensures that the subscription is updated with the latest features and capabilities, including support for private endpoints. Without reregistering, the option to configure private endpoints for the host pool may not be available. Disabling public access on Pool1 is a security measure, but it's not a prerequisite for adding a private endpoint connection; it would typically be done after or in conjunction with setting up private access. Enabling RDP Shortpath for each session host optimizes connection paths but is unrelated to the underlying network connectivity method (public vs. private endpoint). Adding a service endpoint to VNet1 is for accessing specific Azure services over the Azure backbone, not for establishing a private endpoint connection to an AVD host pool itself.
