Refer to the exhibits.
Exhibit 1
Exhibit 2
In the exhibits, VLAN 20 under a device name indicates that the device is configured with that VLAN. The exhibits also indicate whether VLAN 20 is statically configured on each link, either as an untagged or a tagged VLAN. If the link has no label, VLAN 20 is not statically configured on that link.
A network administrator needs to deploy AOS-Switches that use port-based tunneled node. The plan calls for tunneled-node endpoints to be assigned to VLAN 20 and for the Aruba Mobility Controller to handle the tunneled-node traffic at Layer 2. Which exhibit shows the correct plan for VLAN 20 in the wired infrastructure?
A. A
B. B
C. C
D. D

According to Study Guide, the Switch has to communicate to the Controller the vlan. So, I think the answer is C. Although, the Controller can override the default vlan assignment after it authenticates the device.
Correct is D
The tunnel node port based no needed put the vlan of client on trunk ports. It is necessary only betwen controller and Core.
All traffic betwen device and the controller is encapsuled in GRE Tunnel.
The vlan on port is receved dynamically.
