Which network file sharing protocols does NAS support?

Network Attached Storage (NAS) systems typically support protocols designed for file sharing over a network. The two primary protocols used for this purpose are CIFS (Common Internet File System) and NFS (Network File System).

CIFS is widely used in Windows environments and facilitates file sharing over a network, allowing users to upload, download, and manage files remotely. It provides open and cross-platform compatibility, allowing access to shared files from different devices and operating systems.

NFS, on the other hand, is more commonly used in UNIX and Linux environments. It allows users to access files on remote servers as if they were local files, making it particularly effective in environments where UNIX/Linux systems are dominant.

Together, CIFS and NFS cover a broad range of use cases and are fundamental to the functionality of many NAS solutions, enabling seamless file sharing across various types of network devices and operating systems. This makes option C the correct answer, as it accurately identifies the protocols that NAS supports for file sharing.
