An administrator deploys an Aruba wireless solution comprised of:
-a pair of Mobility Masters (MMs)
-multiple Mobility Controllers (MCs) and virtual Mobility Controllers (VMCs)
-an AirWave server
-a ClearPass server
The Aruba Mobility solution runs ArubaOS 8.X.
Which component in this environment globally defines and deploys VLANs for wireless users?
In an Aruba wireless solution running ArubaOS 8.X, the Mobility Master (MM) globally defines and deploys VLANs for wireless users. Mobility Controllers (MCs) and Virtual Mobility Controllers (VMCs) act under the control of the Mobility Master, but the central point of configuration management — including VLAN definition — is the Mobility Master.
C is correct answer https://www.arubanetworks.com/products/networking/gateways-and-controllers/mobility-master/
the problem is that MM do not define anything for the users... it centralized defines config for the MC. The MC apply those configurations to the users... I'll say mobility controllers
