Refer to the exhibit.
A network administrator sets up prioritization for an application that runs between Device 1 and Device 2. However, the QoS for the application is not what the administrator expects.
How can the administrator check if the network infrastructure prioritizes traffic from Device 1 and Device 2?
A. Run a packet capture on Device 2, run the application, and look in the packet capture for a high value DSCP in the IP header.
B. Set up RMON alarms on the switches that trigger when a high number of packets are dropped. Then, run the application and check for the alarm.
C. Clear interface statistics on the switches. Then, run the application and check the interface queue statistics for the switch-to-switch links.
D. Run a packet capture on Device 1, run the application, and look in the packet capture for a high value DSCP in the IP header.

You can check this queue on each switch in the path by clearing statistics, running the applications, and then entering the show interface queuecommand.
