Which two wireless security stewards use Counter Mode Cipher Block Chaining Message Authentication Code Protocol for encryption and data integrity? (Choose two.)
The correct answer is A. WPA2 B. WPA3. 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.

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.
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.
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.
Wi-Fi 6 (802.11ax) is a wireless networking standard, not a security protocol, although it operates with WPA3 for security.
WEP (Wired Equivalent Privacy) uses the RC4 stream cipher and a weak cyclic redundancy check (CRC-32) for integrity, not CCMP.
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.
