Which statement describes file sharing in Unix/Linux environments?

• A. HTTP
• B. iSCSI
• C. NFS
• D. CIFS

Answer: (C)

NFS, or Network File System, is the standard method for sharing files in Unix/Linux environments. It allows a server to export directories that clients can mount over the network, so remote files appear and behave like local ones. This file-level sharing integrates with Unix permissions, mounting tools, and typical networking setups, making it seamless to provide or consume shared folders across multiple hosts. HTTP is for web resource transfer, not mounting remote directories. iSCSI is a block storage protocol that exposes raw disks over the network rather than files. CIFS/SMB is Windows-based file sharing (Linux can access or provide it via Samba, but it isn’t the native Unix/Linux file-sharing mechanism).
