How can Cisco NetFlow be used to aid in the operation and troubleshooting of QoS issues? () A. NetFlow can report on the number of traffic matches for each class map in a configured QoS policy configuration.B. NetFlow records can be used to understand traffic profiles per class of service for data, voice, and video traffic.C. NetFlow can discover the protocols in use and automatically adjust QoS traffic classes to meet policy-map requirements.D. NetFlow can be configured to identify voice and video traffic flows and place them into a lowlatency queue for expedited processing.
