Refer to the exhibit. Which two Lightweight Access Point statements are true? (Choose two.)
A.
An AP that has been upgraded from an autonomous AP to lightweight AP will only
function in conjunction with a Cisco Wireless LAN controller.
B.
LWAPP increases the amount of processing within the APs, enabling them to support
filtering and policy enforcement features.
C.
WLAN controllers provide a single point of management.
D.
Lightweight APs require local configurations using local management.
E.
Real time events such as authentication, security management, and mobility are handled
by the lightweight AP.
F.
Autonomous APs receive control and configuration information from a WLAN controller.
Explanation:
In the Cisco Centralized Wireless LAN Architecture, access points operate in lightweight
mode. The access points associate to a Cisco wireless LAN controller. The controller
manages the configuration, firmware, and control transactions such as 802.1x
authentications. In addition, all wireless data traffic is tunneled through the controller.
The Lightweight Access Point Protocol (LWAPP) is an IETF draft protocol that defines the
control messaging for setup and path authentication and run-time operations. LWAPP also
defines the tunneling mechanism for data traffic.A lightweight access point discovers a controller using LWAPP discovery mechanisms and
then sends it an LWAPP join request. The controller sends the access point an LWAPP join
response allowing the access point to join the controller. When the access point is joined to
the controller, it downloads its software if the revisions on the access point and controller do
not match. Subsequently, the access point is completely under the control of the controller.
No lightweight access point can operate independently from a WLC, including those
upgraded from an autonomous AP. Each lightweight access point must discover a WLC,
issue an LWAPP join request, and if successful, receive a join response to become joined to
a controller.http://www.cisco.com/en/US/docs/wireless/access_point/conversion/lwapp/upgrade/guide/lw
