220-801 · Question #538
Which of the following is the strongest wireless encryption method?
The correct answer is A. WPA2 AES. WPA2 with AES encryption is the strongest option listed because it uses the Advanced Encryption Standard cipher, which is far more resistant to cryptanalysis than alternatives.

Why each option
WPA2 with AES encryption is the strongest option listed because it uses the Advanced Encryption Standard cipher, which is far more resistant to cryptanalysis than alternatives.
WPA2 (Wi-Fi Protected Access 2) implements the IEEE 802.11i standard and uses AES (Advanced Encryption Standard) in CCMP mode, providing 128-bit block encryption that is considered cryptographically strong and is the current baseline for secure wireless networks. This combination supersedes all other options listed in both protocol strength and cipher strength.
WEP (Wired Equivalent Privacy) uses RC4 with a static key and has known cryptographic weaknesses that allow it to be cracked in minutes using freely available tools.
WPA2 with TKIP uses a stronger protocol than WEP but the TKIP cipher itself is a legacy algorithm considered weaker than AES and is deprecated in modern standards.
WPA uses TKIP as its cipher and implements only a subset of the 802.11i standard, making it less secure than WPA2 AES.
