What is true about users' access to Desktop OS machines when the XenDesktop SQL Server is offline?
The correct answer is D. Users who have connected to their Desktop OS machine in the last 14 days are able to start. When the XenDesktop SQL Server is offline, the local host cache allows only previously connected users to start sessions, based on cached data from the past 14 days.

Why each option
When the XenDesktop SQL Server is offline, the local host cache allows only previously connected users to start sessions, based on cached data from the past 14 days.
New users have no cached session data on the Delivery Controller, so they cannot be brokered when the SQL Server is offline.
Anonymous user access is not a special fallback mode triggered by SQL Server unavailability; access depends on cached connection records.
The ability to start a session is not granted to all users indiscriminately - it is specifically limited to those with valid entries in the local host cache from the prior 14 days.
XenDesktop uses a local host cache on the Delivery Controller that stores brokering data for users who have previously connected. When the SQL Server is unavailable, the broker service falls back to this cache, which retains records for up to 14 days, allowing those users to start new sessions to their Desktop OS machines.
