An engineer must change the wireless authentication from WPA2-Personal to WPA2-Enterprise. Which three requirements are necessary? (Choose three.)
A. EAP
B. 802.1X
C. RADIUS
D. pre-shared key
E. 802.11u
F. fast secure roaming
G. 802.11i
Correct Answer: ACG
Explanation/Reference:
Explanation:
Difference between WPA called Personal and Enterprise is the authentication method:
Personal WPA relies on a PSK secret (Pre-Shared Key), and you don’t need an external server to perform authentication
Enterprise WPA (as defined in the 802.11i standard) uses WPA2 with AES-CCM encryption, and authentication is based on 802.1x/EAP using the RADIUS protocol.
ABC
WPA2 Enterprise implements a mutual authentication scheme, authenticating clients to the wireless network and vice versa using 802.1x EAP, usually with a RADIUS server. This ensures that the client is valid and that the client is associated with a legitimate network. WPA2 Enterprise mode makes use of IEEE 802.1x Layer 2 authentication and as such, use of EAP, which itself supports more than 70 different EAP types. The EAP methods are, among others:
EAP-TLS
EAP-TTLS
PEAP v0 or EAP MS-CHAPv2
PEAP v1 or EAP-GTC
EAP-SIM
ABC is correct because WPA2-Personal also supports 802.11i
