question 349

Multiple Choice

You are the lead network designer hired by Service Provider XYZ to deploy CoS functionality on the core MPLS network (P routers) . The goal of the network design is to provide a complete CoS solution to all customers that purchase services such as dedicated Internet access, MPLS L3VPN, and L2VPN (pseudowire) . Service Provider XYZ has these design requirements: If your design includes eight CoS queues on the Service Provider XYZ MPLS PE router ingress (CE facing) interface, how will customer traffic be classified as it enters the MLS P routers?

• A) The eight CoS queues in the MPLS P router are remapped to the eight CoS queues.
• B) Traffic is classified on the MPLS PE routers on core facing interface. The DSCP value is mapped into EXP field where multiple EXP settings (2+) will be assigned to a single queue throughout the MPLS P routers.
• C) Discard the traffic from the eight CoS queues that does not match the four CoS queues of the MPLS P routers.
• D) The 8 CoS queues in the MPLS P router are remapped to four 4 flow-label queues.
