Which computer system feature is required?

• A. Daily backup
• B. Real-time encryption
• C. No backups required
• D. Cloud-only backups

Answer: (A)

Daily backup is the essential feature because it directly addresses data protection and recoverability. Regular backups create restore points so you can recover from hardware failures, data corruption, or accidental deletion with minimal loss. Making backups daily helps ensure that recent work isn’t lost and that a recovery can be achieved quickly, supporting business continuity and data integrity.

Encryption, while important for keeping data secure, does not ensure that data can be restored if something goes wrong. It protects confidentiality, not availability or recoverability. Saying no backups are required contradicts the need to recover data after incidents. Relying on cloud-only backups can introduce extra dependencies and risks, such as access issues, vendor reliability, or regulatory constraints, whereas a daily backup provides a clear, independent mechanism for data restoration.
