CompTIA A+ Core 2 (220-1102) — Question 390

Which of the following authentication types is the most secure?

Answer options

• A. WPA3
• B. WEP
• C. RADIUS
• D. TACACS+\
• E. WPS

Correct answer: A

Explanation

WPA3 is the latest Wi-Fi security protocol that offers enhanced protection compared to its predecessors. WEP is outdated and insecure, while RADIUS and TACACS+ are not authentication types themselves but protocols for managing access control. WPS is also considered less secure due to vulnerabilities that can be exploited.
