Which of the following defines the key exchange for Internet Protocol Security (IPSEC)?

A.
Internet Security Association Key Management Protocol (ISAKMP)

B.
Internet Key Exchange (IKE)

C.
Security Key Exchange (SKE)

D.
Internet Communication Messaging Protocol (ICMP)

Explanation:
Because Ipsec is a framework, it does not dictate what hashing and encryption
algorithms are to be used or how keys are to be exchanged between devices. Key management
can be handled through manual process or automated a key management protocol. The Internet
Security Association and Key management Protocol (ISAKMP) is an authentication and key
exchange architecture that is independent of the type of keying mechanisms used.
