Question

Which two wireless security stewards use Counter Mode Cipher Block Chaining Message Authentication Code Protocol for encryption and data integrity? (Choose two.)

Options

AWPA2
BWPA3
CWi-Fi 6
DWEP
EWPA

Explanation

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.

Common mistakes.

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