NSE 6 – FortiAuthenticator 6.4 — Question 3

Which EAP method is known as the outer authentication method?

Answer options

• A. MSCHAPv2
• B. PEAP
• C. EAP-GTC
• D. EAP-TLS

Correct answer: B

Explanation

PEAP is the correct answer because it encapsulates a second authentication method within a secure tunnel, serving as the outer authentication method. MSCHAPv2, EAP-GTC, and EAP-TLS do not function as outer methods; instead, they are typically used as inner authentication mechanisms within protocols like PEAP.
