Given: A university is installing 10 WLAN controllers and 500 dual-band IEEE 802.11 ERP/OFDM lightweight access points as part of one WLAN domain. The WLAN controllers will work as a cluster, and will support users from 20 different departments within the university system.

In this environment, how should each WLAN controller connect to the Ethernet infrastructure?

A.
Each WLAN controller should connect between the core layer 3 Ethernet switch and two access-layer Ethernet switches forming 10 distribution segments.

B.
Each WLAN controller should connect to the core layer 3 Ethernet switch via a gigabit (or faster) 802.1Q trunk.

C.
Two WLAN controllers should be connected to the core layer 3 Ethernet switch and the other eight WLAN controllers should be chained in series with those two WLAN controllers forming the cluster.

D.
Each WLAN controller should connect to an access-layer Ethernet switch using a gigabit (or faster) connection.
