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

A.
LWAPP encrypts both control traffic and user data.

B.
LWAPP encrypts user traffic with an x.509 certificate using AES-CCMP.

C.
When set to Layer 3, LWAPP uses a proprietary protocol to communicate with the
Cisco Aironet APs.

D.
LWAPP encrypts control traffic between the AP and the controller.

E.
None of the other alternatives apply.

Explanation:
The LAP and WLC pair use the lightweight access point protocol (LWAPP) as the tunneling
mechanism.
+ LWAPP control messages—Exchanges that are used to configure the LAP and manage its
operation. The control messages are authenticated and encrypted so that the LAP is
securely controlled by only the WLC.
+ LWAPP data—Packets to and from wireless clients associated with the LAP. The data is
encapsulated within LWAPP, but is not encrypted or otherwise secured between the LAP
and WLC.
Data traffic between Access Point(AP) and Controller is encapsulated with LWAPP.
