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.)

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

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?

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 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?

Refer to the exhibit.

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

As part of the network design, ACME Corporation requires the ability to export IPv6 information to
better manage its network. Which version of NetFlow records is required to export this
information?

Which two OSPF design considerations should you implement to support the eventual growth of a
network, so that CPU and memory are unaffected by the size and complexity of the link-state
database in a large service provider network? (Choose two.)

ACME Corporation is deploying a new HR application that requires the network infrastructure to
monitor and react to certain conditions in the network. Which feature should be used to meet this
design requirement?

Refer to the exhibit.

How would you redesign the network to improve availability of the routers 1A and 1B at the core site?
