Given: ABC Company has an IEEE 802.11 WLAN secured by strong authentication (PEAP-EAP-MSCHAPv2) and encryption (CCMP/AES). They wish to implement wVoIP phones, but have noticed that the phones they have selected only supports WPA-Personal using TKIP/RC4.

How can ABC Company maintain their current level of data security while allowing the wVoIP phones network access?

A.
Enable application layer encryption for the voice protocol and implement a wireless intrusion prevention system (WIPS) on the wVoIP network segment.

B.
Use a separate SSID for the wVoIP phones and map this new SSID to a separate VLAN on the wired infrastructure.

C.
Use MAC filtering to the network segment where the wVoIP phones will be used.

D.
Use a secure DHCP server that can restrict access to layer 3 addresses based on user authentication.

E.
Using RBAC, allow only the appropriate voice protocol (SIP, H.323, etc.) to a specific destination address on the network segment where the wVoIP phones will be used.
