A server hosting file shares is an example of which of the following types of storage?

A Storage Area Network (SAN) provides block-level storage access to servers, which then typically format and manage the storage themselves, often for databases or applications, rather than directly serving file shares to end-users.

Network Attached Storage (NAS) is a specialized storage device that provides file-level data storage and retrieval services over a computer network to heterogeneous clients. Servers hosting file shares are prime examples of NAS, as they serve files directly over the network using protocols such as SMB/CIFS or NFS.

SATA (Serial Advanced Technology Attachment) is an interface technology used to connect internal storage devices like hard drives or SSDs to a computer, not a type of network-shared storage system.

SAS (Serial Attached SCSI) is an enterprise-grade interface technology for connecting internal storage devices to a server, offering higher performance and reliability than SATA, but it is not a type of network-shared storage system.
