Question 1

You are tasked to design a QoS policy for a service provider so they can include it in the design of their MPLS core network. If the design must support an MPLS network with six classes, and CEs will be managed by the service provider, which QoS policy should be recommended?
A) map DSCP bits into the Exp field
B) map IP precedence bits into the DSCP field
C) map flow-label bits into the Exp field
D) map IP CoS bits into the IP Precedence field

Question 3

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.

Accepted Answer

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.

Question 4
