Which file system type is designed to store data on a shared disk?

• A. Shared Disk
• B. Network File
• C. Disk File
• D. Database File

Answer: (A)

Storing data on a shared disk requires a file system that coordinates access from multiple hosts to the same storage resource. This type of file system is designed to mount and manage a single disk or volume from several servers at once, handling locking, metadata updates, and cache consistency so that concurrent reads and writes don’t corrupt data. In clustering or high-availability setups, that shared-disk capability is crucial because it allows any node to read or write where the data resides, while the system ensures orderly access and data integrity. The other terms don’t fit this specific scenario. A network file approach focuses on accessing files over a network but doesn’t inherently guarantee synchronized access to the same physical disk across multiple hosts. A Disk File isn’t a standard descriptor for shared storage. A database file refers to data stored within a database engine, not a filesystem designed for multi-host shared access to the same disk.
