To ensure resilient, high-performance user profiles for the Boston office, what should you implement?

Cloud Cache is the correct choice for resilient, high-performance user profiles in Azure Virtual Desktop. It stores multiple copies of the user profile in different storage locations (local cache, Azure page blobs, Azure files), ensuring high availability and performance even if one storage location becomes unavailable. Modifying the Account kind setting of storage1 or its replication settings primarily affects data redundancy and cost, not the real-time performance and resilience of active user profiles in the same way Cloud Cache does. Azure Site Recovery is a disaster recovery solution for virtual machines, not specifically designed for optimizing user profile performance and availability within an AVD session.
