Certified Data Privacy Solutions Engineer (CDPSE) — Question 200

Which of the following protocols BEST protects end-to-end communication of personal data?

Answer options

• A. Transmission Control Protocol (TCP)
• B. Transport Layer Security Protocol (TLS)
• C. Secure File Transfer Protocol (SFTP)
• D. Hypertext Transfer Protocol (HTTP)

Correct answer: B

Explanation

Transport Layer Security Protocol (TLS) is specifically designed to secure communications over a computer network, making it the best choice for protecting personal data in transit. In contrast, TCP is a transport protocol without inherent security features, SFTP is for secure file transfers but not general communication, and HTTP does not provide any encryption or security measures.
