Which virtualization term refers to data virtualization at the file-system level, enabling sharing and protection within software?

• A. Fabric Virtualization
• B. File System Virtualization
• C. Storage Device Virtualization
• D. Storage Virtualization

Answer: (B)

This question tests understanding of file-system level data virtualization. File System Virtualization is the term that captures this idea: it abstracts and presents files from multiple storage sources as a single, unified namespace inside software, enabling applications to share files securely and with consistent protection without needing to know where the data actually resides. It focuses on the file layer, enforcing access controls and policies at that level. Other terms describe virtualization at lower levels—block storage, devices, or the storage fabric—rather than at the file system, so they don’t convey the same emphasis on file sharing and protection within software.
