I'm pretty sure C is also true. The PE device should use MPLS EXP bits to differentiate between traffic flows, right? I remember learning that in class.

I'm not sure about A, D, and E. Can someone explain why they are not true for a PE device?

I agree with you, Gertude. I also think C is true because a PE device uses MPLS EXP bits to differentiate traffic flows.

B and E seem like the correct options. The PE device in a QoS-enabled network should classify and mark customer traffic, and it should also pass macroflows while optionally changing QoS markings.

I think B is true because a PE device does classify and mark customer traffic.
