Question

You have an Azure Virtual Desktop deployment that contains the host pools shown in the following table. You plan to use app attach. In which host pools can the session hosts use app attach?

Options

  • APool1 and Pool2 only
  • BPool1 and Pool3 only
  • CPool2 and Pool4 only
  • DPool1, Pool2, and Pool3 only
  • EPool1, Pool2, Pool3, and Pool4

Explanation

Azure Virtual Desktop app attach requires session hosts running Windows 10 or Windows 11 Enterprise multi-session, or Windows 10/11 Enterprise (single-session). Windows Server OS and older operating systems are not supported. Based on the referenced host pool table, Pool1 and Pool2 contain session hosts with a supported OS (Windows 10/11 Enterprise or multi-session), while Pool3 and Pool4 run an incompatible OS such as Windows Server, making them ineligible for app attach. Always verify the session host OS version as the primary eligibility check for app attach.
