Refer to the exhibit.
It was taken from the switch where the Cisco WLC connects to and for which the switch port to the Cisco WLC is configured to trust CoS. The customer has an SSID in place for their VoWLAN whose QoS profile has been set to Platinum. When the IP packet egresses the switch to which the Cisco WLC is connected, the switch interfaces are configured to use the mls qos trust dscpcommand, but a packet trace on the far end reveals that the DSCP marking is set to AF41 and not to EF.
Which option can cause the IP packet to be remarked to the lower QoS value?
A . A switch in the path remarks the binary value in the packet to 011.010.
B . A policy map is applied to an interface by using the violate-action policed-dscp-transmit command.
