Which virtualization term refers to virtualization of data at the file-system level to enable sharing and protection?

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

Answer: (A)

File system virtualization centers on virtualizing data at the level of files and directories, presenting a shared, consistent view that multiple users or systems can access while enforcing protection through permissions and access controls. It enables sharing by providing a common namespace and consistent metadata, and it protects data by applying security policies directly at the file system level. This differs from fabric virtualization, which focuses on the network fabric; storage virtualization, which abstracts physical storage into a single pool at the block level; and storage device virtualization, which deals with virtualization of the physical devices themselves. So, the term that matches virtualization of data at the file-system level to enable sharing and protection is file system virtualization.
