Question

Which of the following statements are true about network-attached storage (NAS)? Each correct answer represents a complete solution. Choose all that apply.

Options

ANAS systems do not contain hard disks.
BNAS uses file-based protocols, such as NFS, SMB/CIFS, or AFP.
CNAS is connected to a computer network providing data access to heterogeneous network clients.
DNAS is file-level computer data storage.

Explanation

Network-attached storage (NAS) is file-level computer data storage connected to a computer network providing data access to heterogeneous network clients. NAS systems contain one or more hard disks, often arranged into logical, redundant storage containers or RAID arrays. It removes the responsibility of file serving from other servers on the network. NAS uses file-based protocols, such as NFS, SMB/CIFS, or AFP. NAS units rarely limit clients to a single protocol.
