BIf the outer EXP is changed, it is copied to the DSCP value.

DThe DSCP value determines how the packet is forwarded

Show Suggested 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.

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