Certified Information Systems Security Professional (CISSP) — Question 395

An organization has been collecting a large amount of redundant and unusable data and filling up the storage area network (SAN). Management has requested the identification of a solution that will address ongoing storage problems. Which is the BEST technical solution?

Answer options

• A. Compression
• B. Caching
• C. Replication
• D. Deduplication

Correct answer: D

Explanation

The best solution in this case is Deduplication, as it removes duplicate copies of data, thereby freeing up valuable storage space. Compression reduces file sizes but may not eliminate redundant data entirely, while Caching and Replication do not specifically address the issue of excessive redundant data.
