From the generalized Windows 10 VHDs stored in the Azure storage account, which disk should you use to create an image for deploying an Azure Virtual Desktop session host?

Disk1 is the correct choice because it represents a generalized Windows 10 VHD. A generalized VHD has been prepared with Sysprep, removing machine-specific information (like SIDs and computer names) and making it suitable for creating multiple identical virtual machines. This is essential for deploying session hosts in Azure Virtual Desktop, as each host needs to be a clean, independent instance. The other disks (Disk2, Disk3, Disk4) are incorrect because they likely represent specialized VHDs, which retain machine-specific information and are only suitable for creating a single VM from that specific VHD, not for creating multiple, identical session hosts.
