Question

Quizplus · Accepted Answer

The Encapsulating Security Payload (ESP) protocol in IPsec provides confidentiality by encrypting the payload of the IP packet. It also provides integrity and authenticity protection for the packet. The other options listed, ISAKMP/Oakley, Authentication Header (AH), and L2TP, do not directly provide confidentiality. ISAKMP/Oakley is used for key exchange, AH provides authenticity and integrity protection but not encryption, and L2TP is a protocol for tunneling data but does not provide encryption or confidentiality on its own.
