Which Group Policy setting should be enabled to optimize Azure Virtual Desktop session hosts for VDI use?

To optimize Azure Virtual Desktop session hosts for Virtual Desktop Infrastructure (VDI) use, enabling the Group Policy setting that prevents the Background Intelligent Transfer Service (BITS) client from using Windows BranchCache is advantageous. In this context, BITS is used to transfer files asynchronously between computers using idle network bandwidth. When BITS operates with Windows BranchCache, it may introduce additional latencies and complexities that can negatively affect the performance of VDI sessions.

By disabling the integration of BITS with BranchCache, you minimize the overhead associated with content retrieval and ensure smoother operation of virtual desktop connections. This is particularly important in a VDI environment, where performance and responsiveness are crucial for user experience.

On the other hand, the other options may not necessarily contribute to the optimization of VDI experiences. For instance, allowing the Offline Files feature can result in unnecessary consumption of local resources. Enabling Hotspot Authentication and turning on BranchCache can complicate network performance and resource allocation further, which is not ideal in a VDI setting where efficiency and speed are paramount.
