CompTIA Security+ (SY0-501) — Question 471

A company needs to implement a system that only lets a visitor use the company's network infrastructure if the visitor accepts the AUP. Which of the following should the company use?

Answer options

• A. WiFi-protected setup
• B. Password authentication protocol
• C. Captive portal
• D. RADIUS

Correct answer: C

Explanation

The correct answer is C, as a captive portal presents users with a webpage that they must interact with before gaining network access, typically to accept the AUP. Options A and B do not provide a means for user agreement, and D (RADIUS) is primarily for authentication and accounting, not for policy acceptance.
