B) If the provider moved to a Short Pipe mode model, it would allow them to implement customer-specific QoS policy on the PE egress.
C) The Short Pipe mode derives the outbound classification of the WRED and WFQ based on the DiffServ policy of the provider.
D) The Pipe mode provides the isolation between the customer and provider DiffServ domains, while maintaining a simpler support model.

2. A customer reports that the packets from their custom TCP application, which is currently marked as DSCP AF43, is being dropped more frequently than desired. All of the links in service provider network are using DSCP-based WRED. What can be changed to best improve the drop rate of the customer's custom application without causing major problems for the other traffic classes?

A) The Differentiated Services field value in the IP packet header.
B) The topmost MPLS label EXP value.
C) The packet is re-evaluated, remarked, and the PHB is based on this new marking.

5. Refer to the exhibit.

Traffic in CLASS-B is not getting a minimum bandwidth of 192 kb/s in this policy map. What can be done to correct this?

A) Set the shape rate to a CIR higher than 192 kb/s.
B) The shape peak command should be used instead of the shape average command.
C) Decrease the maximum queue size.
