Detailed Explanation:

Rationale for Correct Answer:

HPE GreenLake for File Storage (powered by VAST Data) delivers scale-out NAS capabilities with native data protection, snapshots, and disaster recovery integration. It is designed for enterprises that need both scalability and integrated protection in a single consumption or CapEx model.
