What is a characteristics of the Pipe model for MPLS QoS?

Show Suggested Answer Hide Answer
Suggested Answer: C

In the Pipe model of MPLS QoS, the MPLS EXP bits are set by the Customer Edge (CE) device. This model allows the CE to mark the packets, and these markings are retained throughout the MPLS network until they reach the egress Provider Edge (PE) router. The PE router does not alter the MPLS EXP value, ensuring that the QoS policy applied by the customer is preserved end-to-end.

Pipe down, guys. I think A is the only one that makes sense for the Pipe model characteristics.

Definitely, A is the most logical choice for the Pipe model.

Yeah, A is the one where the same QoS policy is applied to all customer traffic.

The DSCP value determining the forwarding? Nope, that's not the Pipe model either. D is not the right answer.

The CE sets the MPLS EXP bits? No way, that's not the Pipe model. C is incorrect.

I think the answer is D, because the DSCP value determines packet forwarding.

Changing the outer EXP and copying it to the DSCP? That's not how the Pipe model works, so B is wrong.

The Pipe model is all about applying the same QoS policy on the egress PE, so A is definitely the correct answer.
