How can the network administrator identify these flows and mark QoS accordingly?

Users run encrypted Skype for Business traffic with no WMM support over an Aruba Mobility Master (MM)-Mobility Controller (MC) based network. When voice, video, and application sharing traffic arrive at the wired side of the network, all the flows look alike due the lack of L2 or L3 markings.

How can the network administrator identify these flows and mark QoS accordingly?
A . Confirm the MC is the Openflow controller of the MMs and Openflow is enabled in VAP and the firewall
roles. Then enable WMM in a VAP profile.
B . Confirm the MM is the Openflow controller of the MCs and Openflow is enabled in VAP and the firewall
roles. Then integrate the MM with the Skype4Business SDN API, and enable the Skype4Business ALG in
the UCC Profiles.
C . Confirm the MC is the OpenFlow controller of the MMs and Openflow is enabled in VAP and the firewall roles. Then enable the Skype4Business ALG in the UCC profiles.
D . Use a media firewall policy that match these three flows, and use permit and TOS actions with 56, 40, and 34 values for voice, video, and application sharing, respectively. Then enable the Skype4Business ALG in the UCC profiles.
