Multiple answer, multiple-choice

In the Split-MAC architecture, which of the following are considered non-real-time functions handled by the wireless LAN controller? (Choose two.)

A.    Beacon generation.
B.    Frame translation and bridging functions.
C.    Probe response.
D.    MAC layer encryption.
E.    System-wide policies for user mobility, QoS and security.

Answer:
B, E

Tutorial:
In the Split-MAC architecture, processing of 802.11 data and management protocols and access point capabilities are distributed between a lightweight access-point (LWAP) and a centralized wireless LAN controller (WLC).

Time-sensitive and real-time functions, such as beacon generation, probe response and MAC layer encryption, are handled in the LWAP.

Non-real-time functions, such as 802.11 management protocol, frame translation and bridging functions, plus system-wide policies for user mobility, QoS and security, are handled by the WLC.
