Which registry setting must be configured to use an Azure page blob storage account with FSLogix?

To use Azure page blob storage accounts with FSLogix, the configuration of the CCDLocations registry setting is essential. This setting specifies the location for storing user profile containers in a cloud-based environment. When using Azure page blobs as the backend for FSLogix profiles, the CCDLocations value must point to the appropriate Azure storage account and container where the FSLogix profile disks will reside.

Utilizing Azure page blobs is beneficial due to their capability to handle large amounts of data with high availability and performance, making them ideal for storing user profiles in a Virtual Desktop Infrastructure (VDI) like Azure Virtual Desktop. By correctly setting the CCDLocations registry key, you ensure that FSLogix can locate and manage the user profiles effectively.

The other choices pertain to different aspects of FSLogix functionality but are unrelated to the configuration of Azure page blob storage. For instance, ProfileDirSDDL relates to security descriptor definition language settings for profile storage, RedirXMLSourceFolder deals with settings for redirection, and VHDLocations pertains to physical locations for virtual hard disks. These do not influence the ability to utilize Azure page blobs specifically.
