Which solution should you recommend to support synchronous replication of FSLogix profiles in Azure?

FSLogix Cloud Cache is the recommended solution for supporting synchronous replication of FSLogix profiles in Azure because it is specifically designed to work with FSLogix profile containers. This feature allows user profiles to be cached and replicated across multiple storage locations in a manner that is seamless and efficient for users and administrators alike.

By leveraging FSLogix Cloud Cache, you can ensure that user profile data is consistently available, enabling users to access their profiles from different session hosts without experiencing downtime or loss of data. This functionality is especially beneficial in scenarios where high availability and performance are critical, such as in virtual desktop environments.

The other options do not provide the same specialized capabilities as FSLogix Cloud Cache for handling user profiles in the context of Azure Virtual Desktop. For example, Azure NetApp Files and Azure Premium Files are excellent storage solutions but lack the specific features tailored for FSLogix profiles, such as built-in caching and replication for user sessions. Azure Storage object replication, while useful for data redundancy, does not focus on the user profile use case and lacks the functionality required for optimal FSLogix operation in desktop environments.
