Which current Wi-Fi security option is widely adopted and uses AES-CCMP encryption?

• A. WEP
• B. WPA
• C. WPA2
• D. WPA3 Personal

Answer: (C)

AES-CCMP provides strong confidentiality and data integrity for Wi‑Fi by using the AES cipher with CCMP mode. This combination is what WPA2 standardized and became the widely deployed security option, because it replaces weaker RC4-based methods with a robust, modern encryption approach. WEP is outdated and insecure because it relies on weak, easily crackable encryption. WPA introduced TKIP to fix some WEP flaws, but it still uses RC4 and isn’t as strong as AES-CCMP. WPA2 brought AES-CCMP as the standard, delivering far better protection and becoming the default in most networks. WPA3 Personal exists and improves security further, but it isn’t as universally adopted yet.
