Which description best captures typical RAID usage in multi-user environments?

• A. Data spread out over several disks, users access simultaneously
• B. Graphic design software
• C. Single-disk backups
• D. Low-cost printers

Answer: (A)

RAID distributes data across multiple disks so several users can read and write at the same time. This parallel access boosts performance in a multi-user environment, because I/O operations can be handled by different drives concurrently. Many RAID configurations also add redundancy, helping protect data so access isn’t lost if a drive fails. This combination—faster simultaneous access with protection against disk failure—best fits typical RAID use in multi-user settings. Other scenarios aren’t describing how storage is organized: using graphic design software is about the type of application, not how data is stored; single-disk backups describe a non-RAID setup and don’t capture the concurrency and redundancy RAID provides; low-cost printers are unrelated to storage architecture.
