What facts are true regarding controllers and APs in a Split MAC architecture?
A.
An IP tunnel is established between the AP and controller for AP management and control functions.
B.
Using centralized data forwarding, APs never tag Ethernet frames with VLAN identifiers or 802.1p CoS.
C.
With 802.1X/EAP security, the AP acts as the supplicant and the controller acts as the authenticator.
D.
Management and data frame types must be processed locally by the AP, while control frame types must be sent to the controller.
The Answer Is:
A
This question includes an explanation.
Explanation:
The fact that is true regarding controllers and APs in a Split MAC architecture is that an IP tunnel is established between the AP and controller for AP management and control functions. A Split MAC architecture is a WLAN architecture where some of the MAC layer functions are performed by the APs (such as encryption, decryption, and frame acknowledgement) and some are performed by the controllers (such as authentication, association, roaming, and QoS). To communicate with each other, the APs and controllers establish an IP tunnel that carries the management and control frames between them. The IP tunnel can use protocols such as Lightweight Access Point Protocol (LWAPP) or Control And Provisioning of Wireless Access Points (CAPWAP).
