Tom works as a network administrator in a multinational organization having branches across North America and Europe. Tom wants to implement a storage technology that can provide centralized data storage and provide free data backup on the server. He should be able to perform data backup and recovery more efficiently with the selected technology. Which of the following storage technologies best suits Tom's requirements?
Correct Answer: D
Network-attached storage (NAS) is the most suitable technology for Tom's requirements. NAS systems are designed to provide centralized data storage, allowing multiple clients or computers to access the same storage space. This centralization simplifies data management, protection, and backup. NAS systems typically include features that support efficient data backup and recovery, such as automatic backup to other devices and fault tolerance through RAID configurations. Unlike direct-attached storage (DAS), which is limited to one user at a time, NAS allows multiple users to access the storage simultaneously, making it ideal for a multinational organization with dispersed teams. NAS also offers remote data availability, which is beneficial for Tom's organization that spans across different regions.
