Which of the following is the wireless encryption standard associated with WPA2?

WPA2 uses AES-CCMP (Advanced Encryption Standard - Counter Mode with Cipher Block Chaining Message Authentication Code Protocol) as its mandatory encryption mechanism. AES provides 128-bit block encryption and CCMP provides data integrity and confidentiality, making WPA2 significantly more secure than its predecessors.

EAP (Extensible Authentication Protocol) is an authentication framework used in 802.1x enterprise environments to handle credential exchange; it is not an encryption cipher associated with WPA2.

WEP (Wired Equivalent Privacy) is the original, cryptographically broken wireless encryption standard that WPA2 was designed to replace and has no association with WPA2.

802.1x is a port-based network access control standard used for authentication in enterprise WPA2 deployments, but it is an authentication mechanism, not the encryption standard itself.
