QUESTION NO: 8
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

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.
