As a salesperson, you have been contacted by an automobile dealership that currently manages each of their 5 SOHO-class access points individually. The owner of the dealership contracts his nephew for the dealership's network administration, but the nephew admits to a limited knowledge of WLAN technology. The dealership owner and his nephew want you to advise them on how they can simplify the management of their wireless network. You tell them that they are currently managing __________ access points, and they could consider _____________ to ease the management burden.
A. Autonomous; a WLAN controller-based architecture
B. Mesh; a Wireless Network Management System
C. MIMO; copying one configuration file and importing it into the other access points
D. Root; installing a Wireless Intrusion Protection System (WIPS) for management
E. Controller-based; a WLAN controller to manage their current access points
