Which of the following is a file sharing protocol for Unix/Linux systems? SMB CIFS NFS FTP

The file sharing protocol specifically designed for Unix/Linux systems among the options you provided is **NFS (Network File System)**. While SMB (Server Message Block) and CIFS (Common Internet File System) are also used for file sharing, they are primarily associated with Windows systems, although they can be used in Unix/Linux environments as well. FTP (File Transfer Protocol) is used for transferring files but is not a file sharing protocol in the same sense as NFS.
