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?

In a redesign of a multiple-area network, it is recommended that summarization is to be
implemented. For redundancy requirements, summarization is done at multiple locations for
each summary. Some customers now complain of higher latency and performance issues for a
server hosted in the summarized area. What design issues should be considered when creating
the summarization?

When designing a WAN that will be carrying real-time traffic, what are two important reasons
to consider serialization delay? (Choose two.)

Which two techniques are used in a network design to slow down the distribution of topology
information caused by a rapidly flapping link? (Choose two.)
