Answers

Confidentiality
D.
Integrity
Answers
D.
Integrity
Suggested answer: C

Explanation:

The Authentication Header (AH) is a component of the IPsec protocol suite that provides authentication and integrity to the communications. AH ensures that the contents of the communications have not been altered in transit (integrity) and verifies the sending and receiving parties (authentication). However, AH does not provide confidentiality, which would involve encrypting the payload data. Confidentiality is provided by the Encapsulating Security Payload (ESP), another component of IPsec.

Reference:

RFC 4302, 'IP Authentication Header'.
