Networking Fundamentals — Question 39

Which wireless authentication method provides the highest level of security?

Answer options

• A. Wired Equivalency Privacy (WEP)
• B. IEEE 802.lln
• C. WI-FI Protected Access (WPA)
• D. IEEE 802.11a

Correct answer: C

Explanation

WI-FI Protected Access (WPA) is the correct answer because it enhances security through stronger encryption methods compared to WEP and provides better protection against unauthorized access. In contrast, WEP is outdated and vulnerable, while IEEE 802.11a and IEEE 802.lln are standards for wireless networks that do not specifically address authentication security levels.
