Which issue with this plan needs to be addressed?

The implementation plan for AOS-Switches calls for them to implement port-based tunneled node. The Aruba Mobility Controllers that will support the AOS-Switches run software 8.1. The controllers will also support APs, are managed by Mobility Master, and use clustering.

Which issue with this plan needs to be addressed?
A . The controllers cannot support tunneled node with AOS-Switches when they are managed by the Mobility Master.
B . The switches cannot connect to controllers that also support APs.
C . The controllers must have their software updated before they can support the switches.
D . The switches must use role-based tunneled node to work with clustering controllers.

Answer: A
