What protocol is typically associated with network file systems in NAS environments?

Network file systems in NAS (Network Attached Storage) environments are primarily associated with the NFS (Network File System) protocol. NFS is specifically designed to allow access to files over a network in a way that is akin to accessing local storage. This protocol enables users and applications to read and write to files on a remote server as if they were local files, which is essential in a NAS setup where multiple clients need to share and access files stored on a centralized storage device effectively.

NFS operates over standard network protocols and supports various features such as file locking, which helps maintain data integrity when multiple clients are accessing the same files. Its design is optimized for Unix and Linux environments but has also been implemented in other operating systems. The protocol is widely used in enterprise environments due to its efficiency and ease of integration with existing network infrastructures.

The other options relate to different storage-related protocols that are typically used in various contexts. For instance, Fibre Channel is mostly associated with SAN (Storage Area Network) environments, iSCSI is used to link storage facilities over IP networks (often a SAN technology), and SMB (Server Message Block) is a protocol mainly used in Windows environments for sharing files and printers. While SMB could be employed in NAS contexts, NFS
