Question

Options

Explanation

NAS (Network Attached Storage) provides file-level storage access over a network using protocols such as NFS (Network File System, common in Unix/Linux environments) and CIFS/SMB (Common Internet File System, used in Windows environments) - making choice A correct. NAS devices are accessible over the network and can be shared among multiple servers simultaneously (D), which is one of its primary advantages over DAS. NAS is generally slower than DAS (Direct Attached Storage) because it introduces network latency and protocol overhead (E). Choice B is incorrect - block-level access over a network is a characteristic of SAN (Storage Area Network), not NAS. Choice C is incorrect - DAS is referred to as 'captive storage' because it is dedicated to a single server; NAS is shared storage.
