Given: ABC Company uses their dual-band ERP/OFDM 802.11 WLAN extensively to move general data traffic, wVoIP data, and guest access Internet-only data.

What is the best approach to achieve the appropriate level of security and QoS for each data type while minimizing troubleshooting complexity across the entire WLAN?

A.
Each QoS and security level should have its own ESSID.

B.
TPC and DFS should be implemented for QoS and RSNAs should be implemented for security. This is true for ERP and OFDM.

C.
Each data type should be on a separate WLAN, and each WLAN should be tied to a separate VLAN in the WLAN controller.

D.
Implement DiffServ bit detection and transference for QoS and security.

E.
Guest access should use ERP and all other traffic should use OFDM.
