HP0-J73 · Question #302
What is a function of Distributed File System Replication (DFSR)?
The correct answer is D. Replicates block data between HP SmartArray controllers. In this HP storage exam context, DFSR refers to an HP-specific block replication function associated with SmartArray controllers, not the Windows Server file-level replication service.

Why each option
In this HP storage exam context, DFSR refers to an HP-specific block replication function associated with SmartArray controllers, not the Windows Server file-level replication service.
Detecting changes and replicating only the changed file blocks describes the behavior of Windows Server DFSR using Remote Differential Compression (RDC), which is a file-system-level service unrelated to HP SmartArray.
Replicating deduplicated block data across servers and sites describes a WAN-optimized or deduplication-aware replication product such as HP StoreOnce, not DFSR.
Detecting changes and replicating the entire changed file describes a basic file-copy replication approach, not the specific block-level function attributed to DFSR in the HP storage context.
The HP exam treats DFSR as a SmartArray-level feature that replicates block data directly between HP SmartArray controllers, operating at the storage controller layer rather than the file system layer. This distinguishes it from Windows DFSR and positions it as a controller-driven block replication mechanism within HP's storage stack.
