CompTIA Security+ (SY0-701) — Question 550

Which of the following best protects sensitive data in transit across a geographically dispersed infrastructure?

Answer options

• A. Encryption
• B. Masking
• C. Tokenization
• D. Obfuscation

Correct answer: A

Explanation

Encryption is the most effective way to secure sensitive data during transmission, as it converts information into a format that is unreadable without the proper decryption key. Masking, tokenization, and obfuscation serve different purposes; they may hide or alter data but do not provide the same level of security for data in transit as encryption does.
