Which concept describes having multiple copies of data across different storage solutions, including cloud storage, to improve data availability?

• A. Data Redundancy
• B. Data Normalization
• C. Data Deduplication
• D. Data Partitioning

Answer: (A)

The concept being tested is data redundancy: creating multiple copies of data across different storage locations, including cloud storage, to keep data accessible even if one storage path fails. This approach boosts availability by providing failover options, geographic distribution, and recovery capabilities in case of outages or disasters. The other terms describe different ideas. Normalization focuses on organizing data in a database to minimize duplication, which actually reduces redundancy. Deduplication is a storage optimization technique that removes duplicate data to save space, rather than intentionally keeping multiple copies for availability. Partitioning splits data into smaller pieces to improve performance or manageability, not primarily to improve access when a single storage component fails. So, having multiple copies across diverse storage solutions to enhance access and resilience is data redundancy.
