What is the role of IKE within the IPsec protocol:

A.
peer authentication and key exchange

B.
data encryption

C.
data signature

D.
enforcing quality of service

Explanation:
“In order to set up and manage Sas on the Internet, a standard format called the
Internet Security Association and Key Management Protocol (ISAKMP) was established. ISAKMP
provides for secure key exchange and data authentication. However, ISAKMP is independent of
the authentication protocols, security protocols, and encryption algorithms. Strictly speaking, a
combination of three protocols is used to define key management for IPSEC. These protocols are
ISAKMP, Secure Key Exchange Mechanism (SKEME) and Oakley. When combined and applied
to IPSEC, these protocols are called the Internet Key Exchange (IKE) protocol.” Pg. 222 Krutz:
