Certified Information Systems Security Professional (CISSP) — Question 22

Which of the following protection is provided when using a Virtual Private Network (VPN) with Authentication Header (AH)?

Answer options

• A. Sender non-repudiation
• B. Multi-factor authentication (MFA)
• C. Payload encryption
• D. Sender confidentiality

Correct answer: A

Explanation

The correct answer is A, as Authentication Header (AH) ensures that the sender cannot deny having sent a message, providing non-repudiation. Options B and C are incorrect because AH does not provide multi-factor authentication or payload encryption. Option D is also incorrect since AH focuses on integrity and authentication rather than confidentiality.
