Given: ABC Corporation’s 802.11 WLAN is comprised of a single WLAN controller and 30 access points. They implemented IPSec VPN technology to secure their wireless communication because it was the strongest security solution available at the time it was implemented.
IT management has decided to implement wVoIP and is concerned with security since today’s wVoIP phones do not support IPSec.
As the wireless network administrator, what new security solution do you suggest?
A.
Migrate all 802.11 devices to WPA-Enterprise, and separate wVoIP communications from regular data by putting them on a different frequency band.
B.
Migrate all 802.11 devices to WPA2-Enterprise, and use WPA2-Personal to secure wVoIP communications on a separate VLAN.
C.
Migrate all 802.11 devices to WPA2-Personal, and use the RBAC feature on the WLAN controller to limit protocols and destinations for wVoIP clients.
D.
Migrate all 802.11 devices to WPA-Personal, and implement a secure DHCP server to allocate addresses from a special subnet for the wVoIP phones.
E.
Migrate all 802.11 devices to WPA2-Enteprise, and use the RADIUS server to implement MAC-based authentication of wVoIP phones.
