Which configuration steps should the network administrator take to classify and mark voice and video traffic with UCC heuristics mode?

Users run Skype for Business on wireless clients with no WMM support over an Aruba Mobility Master (MM) – Mobility Controller (MC) based network. When traffic arrives at the wired network, it does not include either L2 or L3 markings.

Which configuration steps should the network administrator take to classify and mark voice and video traffic with UCC heuristics mode?
A . Enable WMM in a VAP profile, and explicitly permit voice and video UDP ports in a firewall policy.
B . Confirm OpenFlow is enabled in the user role and VAP profile. Then enable WMM in a SSID profile, and explicitly permit voice and video UDP ports in a firewall policy.
C . Confirm the MC is the Openflow controller of the MMs and Openflow is enabled in VAP and firewall roles. Enable Skype4Business ALG in UCC profiles.
D . Confirm MM is the Openflow controller of MCs and Openflow is enabled in VAP and firewall roles. Enable Skype4Business ALG in UCC profiles.
