You work as a network administrator for WebPerfect Inc. You configure both WPA and EAP authentications on a client computer in the company’s wireless network. Where will the encryption key be located during the active user session?
Each correct answer represents a part of the solution. Choose two.

A.
On the AP

B.
On the client

C.
On the controller

D.
Shared with all clients in the network

Explanation:
When WPA encryption is used on a client, the client and the AP will have the same encryption key during the active user session. This encryption key is called PMK (Pairwise Master Key). Answer option D is incorrect. The WPA encryption key is not shared on all clients during the active user session.
Answer option C is incorrect. The WPA encryption key is not located on the controller during the active user session.
What is WPA?
Wi-fi Protected Access (WPA) is an interoperable security standard for Wireless LAN (WLAN). For using WPA, encryption is required. WPA provides encryption by using Temporal Key Integrity Protocol (TKIP). TKIP uses a new encryption algorithm, which is stronger than WEP algorithm. 802.1x authentication is required in WPA.
What is EAP?
Extensible Authentication Protocol (EAP) is an authentication protocol that provides support for a wide range of authentication methods, such as smart cards, certificates, one-time passwords, public keys, etc. It is an extension to Point-to-Point Protocol (PPP), which allows the application of arbitrary authentication mechanisms for the validation of a PPP connection.
