-
A
Data duplication
-
B

-
C
Redundant Offsite Storage

D
RAID
Reveal correct answer
Correct answer: D
Explanation
Correct Answer: D. RAID
Both Redundant Array of Independent Disks (RAID) and Redundant Array of Independent Tapes (RAIT) are technologies that distribute data across multiple disks or tapes respectively. They are designed to improve performance and provide data redundancy.
Incorrect Answers Explained:
A. Data duplication: Incorrect because while it provides a copy of the data, it doesn't inherently distribute data across multiple media for enhanced performance.
B. Single Disk Backup: Incorrect as it refers to a backup on a single disk and doesn't offer the redundancy or performance benefits of RAID/RAIT.
C. Redundant Offsite Storage: Incorrect because while it may store backup copies offsite, it doesn't specify the method of data distribution or performance enhancement like RAID/RAIT.
