CompTIA Security+ (SY0-601) — Question 480

A network administrator is setting up wireless access points in all the conference rooms and wants to authenticate devices using PKI. Which of the following should the administrator configure?

Answer options

• A. A captive portal
• B. PSK
• C. 802.1X
• D. WPS

Correct answer: C

Explanation

The correct answer is C, 802.1X, which is a network access control protocol that provides authentication using PKI. Option A, a captive portal, is typically used for guest access, while B, PSK, involves pre-shared keys and does not utilize PKI. Option D, WPS, is designed for simplifying the connection process and does not provide the required level of security with PKI.
