Selected Answer: A
The IP phone will mark the voice traffic at the phone, so trust this on SW1. The PC traffic will need to be marked at SW2. Marking is occurring as close to the edge as possible without client intervention. Option ‘A’ correctly identifies this.

I am pretty sure all/most of the traffic marking should be done on the lower layers ie access layer. Answer A seems correct.
