CompTIA Data+ (DA0-001) — Question 304

Which of the following data protection methods provides confidentiality for data in transit?

Answer options

• A. De-identification
• B. Encryption
• C. Masking
• D. Anonymization

Correct answer: B

Explanation

Encryption is the correct answer because it encodes data, making it unreadable to unauthorized users during transmission. The other methods, such as de-identification, masking, and anonymization, primarily focus on removing or obfuscating identifiable information rather than securing data in transit.
