On an enterprise IEEE 802.11 WLAN supporting both voice and data, why is WPA2-Personal security often preferred over WPA2-Enterprise security for voice-enabled devices?

A.
WPA2-Personal is more easily configured on the voice-enabled client devices than WPA2-Enterprise.

B.
WPA2-Personal supports IEEE 802.11 fast/secure roaming between access points, whereas WPA2-Enterprise deployments may not.

C.
WPA2-Enterprise voice-enabled devices consume battery life at rate of almost double that of WPA2-Personal.

D.
WPA2-Personal imposes less encryption overhead than WPA2-Enterprise, resulting in better performance.

E.
Voice-enabled devices use application layer (L7) security mechanisms, minimizing the need for scalable data link (L2) security.
