Assume That Administrators Accept the Default Forwarding Mode for WLANs

Assume that administrators accept the default forwarding mode for WLANs. How does wireless user traffic flow in a master-local architecture, and how does it flow in a Mobility Master (MM) architecture?

A) In the master-local architecture, traffic is tunneled to a local Mobility Controller (MC) to handle. In a MM architecture, all traffic is tunneled to the MM to handle.
B) In the master-local architecture, all traffic is tunneled to the master controller to handle. In a MM architecture, all traffic is tunneled to the MM to handle.
C) In both architectures, traffic is tunneled to a Mobility Controller (MC) to handle.
D) In both architectures, APs forward corporate user traffic locally and tunnel guest user traffic to a Mobility Controller (MC) to handle.
