Which statement about the Lightweight Access Point Protocol (LWAPP) protocol is true?

LDAP is being used throughout the Company wireless network. Which statement about the
Lightweight Access Point Protocol (LWAPP) protocol is true?

A.
The processing of 802.11 data and management protocols and access point capabilities
is distributed between a lightweight access point and a centralized WLAN controller.

B.
LWAPP advertises its WDS capability and participates in electing the best WDS device
for the wireless LAN.

C.
LWAPP aggregates radio management forward information and sends it to a wireless
LAN solution engine.

D.
LWAPP authenticates all access points in the subnet and establishes a secure
communication channel with each of them.

E.
None of the other alternatives apply

Explanation:
The control traffic between the access point and the controller is encapsulated with the
LWAPP. The control traffic is encrypted via the Advanced Encryption Standard (AES). The
data traffic between the access point and controller is also encapsulated with LWAPP. The
data traffic is not encrypted. It is switched at the WLAN controller, where VLAN tagging and
quality of service (QoS) are also applied.
The lightweight architecture splits the processing of the 802.11 protocol between two
devices, the access point and a centralized Cisco WLC. The processing of the 802.11 data
and management protocols and the access point functionality is also divided between the
two devices. This approach is called split MAC.
