Which type of NAS storage level is described by storing data as files?

• A. File level storage
• B. Block level storage
• C. Object storage
• D. Byte level storage

Answer: (A)

In NAS environments, data is organized and accessed as files within a file system. The NAS presents a hierarchical namespace of folders and files to clients, using file-based protocols like SMB or NFS. When you store data this way, the system handles file names, directory paths, permissions, and associated metadata, letting applications read and write whole files through standard file operations.

Block-level storage, by contrast, provides raw chunks of storage to a host (often over a SAN) and relies on the host to run a file system on top of those blocks. Object storage saves data as discrete objects with metadata and a unique identifier, accessed via APIs rather than a traditional file system. Byte level storage isn’t a standard way to describe NAS storage.

So the description “storing data as files” aligns with file-level storage.
