CompTIA A+ Core 2 (220-1002) — Question 142

Which of the following encryption methods is used by WPA2 to improve data security as compared to previous wireless encryption protocols?

Answer options

• A. AES
• B. TKIP
• C. S/MIME
• D. 3DES

Correct answer: A

Explanation

AES (Advanced Encryption Standard) is the encryption method adopted by WPA2, offering stronger security than its predecessors. TKIP is an older method used in WPA, while S/MIME and 3DES are unrelated to wireless encryption protocols and do not provide the same level of security improvements as AES.
