The correct answer is Network Attached Storage (NAS). NAS systems are designed to provide file-level storage services to other devices on a network, which makes it ideal for collaboration among a remote workforce using different operating systems. NAS supports the network file system (NFS) and common Internet file system (CIFS) protocols to allow a wide range of device compatibility, including both Windows and Linux systems, which matches the company's requirement for a flexible and interoperable storage solution. Storage Area Network (SAN) provides block-level storage, which does not inherently support file-level operations such as those needed for direct file access or manipulation within operating systems. Object storage is often accessed through APIs or HTTP and is not typically used as a mounted drive on a desktop environment. Direct Attached Storage (DAS) is connected directly to a server or computer and would not provide the networked accessibility required for the company's scenario.
