You work as a network administrator for Web Perfect 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 controller

C.
Shared with all clients in the network

D.
On the client

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 C is incorrect. The WPA encryption key is not shared on all clients during the active user session.

Answer B is incorrect. The WPA encryption key is not located on the controller during the active user session. Fact What is WPA? Hide 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. Fact What is EAP? Hide 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.
