Q

The central office is currently using a combination of 4400 and 2100 series WLAN controllers
running v4.2 and a variety of LWAPP-enabled access points servicing both 2.4 GHz and 5 GHz.
The WLAN deployment has been extended to each remote office by implementing a 526 WLAN
controller running v4.1 and several 521 access points. Wireless client deployment uses EAP-TLS
authentication by use of a centralized RADIUS server plus 802.11n for performance. After the first
remote office deployment, remote office users complain that they are not connecting via 802.11n.
Which will most likely cause this problem?

A. The 521 AP does not support 5 GHz, which prohibits 802.11n.
B. The 521 AP and 526 WLAN controllers do not support AES, which prohibits 802.11n.
C. The 526 WLAN controller does not support external authentication via RADIUS, prohibiting
authentication.
D. The 526 WLAN controller does not support 802.11n with either v4.1 or v4.2.
