What strategy involves setting up multiple partitioned storage drives to enhance data storage and fault tolerance?

• A. Redundant Array of Independent/Inexpensive Disks (RAID)
• B. Mission Critical Mentality
• C. Emergency Operating Procedures (EOPs)
• D. Cyberspace Centers of Excellence (COEs)

Answer: (A)

Using multiple storage disks together in an array to provide redundancy and resilience is a RAID strategy. This approach combines several drives so data is stored across them in a way that allows recovery if one disk fails. Depending on the RAID level, data can be mirrored on multiple disks for exact copies, or encoded with parity information to rebuild lost data, or spread across disks for a balance of capacity, performance, and fault tolerance. This setup keeps data accessible even during failures and can improve read and write performance in some configurations. The other options describe management concepts or organizational programs, not storage architectures, so they don’t address how data storage and fault tolerance are achieved.
