CompTIA A+ Core 2 (220-1102) — Question 319

Which of the following security methods supports the majority of current Wi-Fi-capable devices without sacrificing security?

Answer options

• A. WPA3
• B. MAC filtering
• C. RADIUS
• D. TACACS+

Correct answer: A

Explanation

WPA3 is designed to provide enhanced security features and is widely supported by contemporary Wi-Fi devices, making it the best choice. In contrast, MAC filtering is less secure as it can be easily spoofed, while RADIUS and TACACS+ are authentication protocols that do not directly address Wi-Fi security.
