CompTIA Security+ (SY0-501) — Question 657

A company is deploying a wireless network. It is a requirement that client devices must use X.509 certifications to mutually authenticate before connecting to the wireless network. Which of the following protocols would be required to accomplish this?

Answer options

• A. EAP-TTLS
• B. EAP-MD5
• C. LEAP
• D. EAP-TLS
• E. EAP-TOTP

Correct answer: D

Explanation

EAP-TLS is the correct choice because it utilizes X.509 certificates for mutual authentication, ensuring both the client and server verify each other's identities. The other options, such as EAP-MD5 and LEAP, do not support certificate-based authentication, while EAP-TTLS offers a different approach that does not specifically require X.509 certificates for both parties.
