When designing an MPLS-based LAN extension between DC-1 and DC-2, what are three
advantages of deploying VSS? (Choose three.)

Youare 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:
 The network supports four service queues with equal treatment
for delay, jitter,and packet loss.
 Queues are numbered 0-3, where 0 is the default queue.
 Three queues have one treatment.
 One queue has either one or two treatments.
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?

When network summaries are created for access networks in a network design, how does it
change the behavior of the Shortest Path First (SPF) running in a backbone area?

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?

How should multiple OSPF areas be designed when deployed on a classic three-layer
(core/distribution/access) network hierarchy?

You are designing a network that includes IP QoS. Which two architectures could be used to
ensure that IP QoS is implemented properly? (Choose two.)

Refer to the exhibit.

What limitations exist in this design, given that the access layer devices are expected to
steadily increase by two devices per week for the next year?

Yourcustomer asks you to assist with their traffic policy design. They want to guarantee a
minimum amount of bandwidth to certain traffic classes. Which technique would you advise
them to implement?

What is a key role for the access layer in a hierarchical network design?

What is a key design aspect to be considered when designing an IP network that will be
carrying real-time VoIP traffic?
