Why each option
NAS (Network Attached Storage) is the classic example of shared, file-level storage accessible by multiple clients simultaneously over a standard network.
NAS (Network Attached Storage) is a purpose-built appliance that exposes a shared file system over a network using protocols such as SMB/CIFS or NFS. Multiple clients can connect to and access the same files concurrently, which is the defining characteristic of shared access file-level storage.
DAS (Direct-Attached Storage) is physically connected to and owned by a single host - it is neither networked nor shared by default.
SAN (Storage Area Network) presents raw block-level storage to hosts, not a shared file system; each host formats and manages its own block device independently.
A LUN (Logical Unit Number) is a block-level addressable storage unit carved from a SAN array - it is a block storage construct, not a file-level shared storage technology.
