CISSP – Information Systems Security Architecture Professional (ISSAP) — Question 42

Which of the following protocols uses the Internet key Exchange (IKE) protocol to set up security associations (SA)?

Answer options

• A. IPSec
• B. L2TP
• C. LEAP
• D. ISAKMP

Correct answer: D

Explanation

The correct answer is D, ISAKMP, as it specifically defines procedures for establishing, negotiating, and managing security associations using IKE. IPSec (A) is a suite of protocols that can use ISAKMP for key management, but it is not the protocol that directly uses IKE. L2TP (B) and LEAP (C) are unrelated to IKE and security associations in this context.
