Which of the following is a main advantage of using Network-Attached Storage (NAS) in a data center?

The main advantage of using Network-Attached Storage (NAS) in a data center is its scalability of multiple users. NAS is designed to serve multiple users and applications over a network, allowing easy access and collaboration on shared data. This capability is particularly valuable in environments where many users need to access the same files or data sets, as it provides centralized storage that can accommodate the demands of various users without significant performance degradation.

NAS solutions can easily scale by adding more storage devices to meet increasing data needs. This flexibility makes it an attractive option for organizations that anticipate growth or fluctuating storage requirements. Additionally, NAS typically involves simpler management and maintenance compared to other storage types, further enhancing its appeal for supporting multiple users effectively.

In contrast, the other options do not align closely with the core benefits of NAS. High-performance computing generally pertains to systems designed for intensive compute tasks, while enhanced user interface design and dedicated hardware for applications focus more on application-specific needs rather than the shared, collaborative advantages that NAS provides.
