CompTIA Network+ (N10-009) — Question 193

Which of the following are the main differences between ESP and AH? (Choose two.)

Answer options

• A. AH provides confidentiality through the use of encryption.
• B. ESP provides authentication for IP headers and their payloads.
• C. ESP provides confidentiality through the use of encryption.
• D. AH provides authentication for IP headers and their payloads.
• E. AH provides data origin authorization over shared secret.
• F. ESP provides data origin authorization over shared secret.

Correct answer: C, D

Explanation

The correct answers are C and D because ESP does provide confidentiality through encryption, while AH offers authentication for IP headers and their payloads. Option A is incorrect since AH does not provide confidentiality, and option B is wrong because ESP does not solely focus on authentication for IP headers, which is a function of AH.
