Why each option

WPA2 and WPA3 are wireless security protocols that utilize Counter Mode Cipher Block Chaining Message Authentication Code Protocol (CCMP) to provide robust encryption and data integrity.

AWPA2Correct

WPA2 (Wi-Fi Protected Access II) mandates the use of CCMP, which is based on the Advanced Encryption Standard (AES), for strong data encryption and integrity protection in wireless networks.

BWPA3Correct

WPA3 (Wi-Fi Protected Access 3), the latest generation of Wi-Fi security, continues to use CCMP (and GCMP for WPA3-Enterprise) with AES for enhanced encryption and data integrity, building upon WPA2's foundation.

CWi-Fi 6

Wi-Fi 6 (802.11ax) is a wireless networking standard, not a security protocol, although it operates with WPA3 for security.

DWEP

WEP (Wired Equivalent Privacy) uses the RC4 stream cipher and a weak cyclic redundancy check (CRC-32) for integrity, not CCMP.

EWPA

WPA (Wi-Fi Protected Access) uses TKIP (Temporal Key Integrity Protocol) for encryption and integrity, which was an interim solution before CCMP became widely adopted with WPA2.
