Which of the following storage technologies supports file-level access?

Storage Area Networks (SANs) provide block-level access, presenting storage volumes to servers as if they were local disks, not as shared file systems.

Direct-Attached Storage (DAS) connects storage directly to a single server, which then manages the storage at the block level.

An SSD (Solid State Drive) is a type of storage media that can be used within various storage architectures but is not a storage technology that defines file-level access for networked systems itself.

Network-Attached Storage (NAS) is a dedicated file storage system that allows multiple network clients to access shared files over a network using standard file-sharing protocols such as NFS (Network File System) or SMB/CIFS. Unlike SAN or DAS which provide block-level access, NAS presents storage as file systems directly accessible at the file and folder level.
