Which option best describes storage types?

• A. Block storage
• B. File storage
• C. Object storage
• D. All of the above

Answer: (D)

Storage types come in several models: block, file, and object storage. Each has its own characteristics and typical use cases, and together they cover the main ways data is stored in modern systems. Block storage presents raw storage volumes to a server as blocks, offering high performance and low latency, which is ideal for databases and virtual machines, though you still need to create and manage a file system on top. File storage exposes data through a hierarchical file system over a network (like NFS or SMB), making it easy to share folders and collaborate on documents. Object storage keeps data as discrete objects with metadata and a unique identifier, scaling nicely for unstructured data, backups, media, and archives, and it’s usually accessed via REST APIs. Because storage solutions include all three prominent models, the best description of storage types is that all of the above apply.
