Which of the following provides the MOST secure method …

An organization recently upgraded its wireless infrastructure to support 802.1x and requires all clients to use this method. After the upgrade, several critical wireless

into compliance with the 802.1x requirement. Which of the following provides the MOST secure method of integrating the non-compliant clients into the network?

A.
Create a separate SSID and require the use of dynamic encryption keys.

B.
Create a separate SSID with a pre-shared key to support the legacy clients and rotate the key at random intervals.

C.
Create a separate SSID and pre-shared WPA2 key on a new network segment and only allow required communication paths.

D.
Create a separate SSID and require the legacy clients to connect to the wireless network using certificate-based 802.1x.
