CompTIA Security+ (SY0-601) — Question 486

Which of the following allows for functional test data to be used in new systems for testing and training purposes to protect the real data?

Answer options

• A. Data encryption
• B. Data masking
• C. Data deduplication
• D. Data minimization

Correct answer: B

Explanation

Data masking is the correct answer because it involves altering the original data so that it can be used for testing without revealing sensitive information. Data encryption secures data but does not alter it for testing purposes, data deduplication reduces data redundancy without protecting it, and data minimization limits data collection rather than focusing on its use for testing.
