Implementing and Operating Cisco Security Core Technologies (SCOR) — Question 422

Which cryptographic process provides origin confidentiality, integrity, and origin authentication for packets?

Answer options

• A. AH
• B. IKEv1
• C. IKEv2
• D. ESP

Correct answer: D

Explanation

The correct answer is D, ESP, as it provides confidentiality, integrity, and authentication for packets by encrypting the payload and adding an integrity check. AH (A) only provides integrity and authentication, while IKEv1 (B) and IKEv2 (C) are key management protocols and do not directly offer these security features for packets.
