Selected Answer: D
I believe the answer should be D because typically dhcp configurations on the wlan is not chnaged too often. The wlans job is to send and recieve the dhcp request and ack from the server. What will happen frequently is the wlan will send the dhcp request, in this case the wlan controller will, and from a troubleshooting perspective the dhcp request is on the wire and investigation is done on the wired side.

If investigate into DSCP/CoS converting into WMM, we should capture both side wireless and wired. However, only mentioned about the wired side to capture, more likely need to care about the DHCP transactions rather than the WMM. So, the answer should be "D".
