Youare identifying performance management requirements for a VoIP migration. What three
key performance indicators would you use to track media quality? (Choose three.)

As part of a new network design, you are helping the Network Management Team to develop a
proactive report to identify places in the network where problems may happen. The network
management tool can poll the network devices only via SNMP GET operations. Which two
threshold-crossing metrics should you include in this report? (Choose two.)

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.
How would you design your solution to map the DSCP value properly so that the traffic is
assigned to the respective queues in the Service Provider XYZ MPLS core network?

In which two ways is IPv4 and IPv6 traffic handled in a network design that uses QoS
deployment options? (Choose two.)

Youhave been hired to redesign a network due to issues with congestion. How will a router
function if the QoS mechanism of congestion avoidance is integrated into the existing network
design?

Service provider XYZ plans to provide dedicated Internet access and MPLS L3VPN services to
business customers. XYZ has these design specifications:
 MP-BGP running on the core MPLS P routers with external
Internet routes.
 The core network will include 16 Point of Presence IP POPs
throughout the Asia-Pacific region.
 An additional nine non-P routers will use EBGP peering with
multiple providers for Internet traffic.
 An additional 50 PE routers will provide end customers with
dedicated Internet access and L3VPN services throughout the Asia-Pacific
region.
In what two ways can the MP-BGP be removed from the MPLS P core routers and still provide
dedicated Internet access and MPLS L3VPN services? (Choose two.)

Refer to the exhibit.

An enterprise is migrating its single-area OSPF network from a Frame Relay WAN service to anMPLS L3VPN service. Frame Relay will remain in only a few sites that require increased
resiliency via two different WAN connections.
Which feature could be used in the ?MPLS VPN service provider network to support the design
requirement by ensuring that during normal operation, intersite traffic will only use the MPLS
VPN service and not the old Frame Relay service?

When creating a network design that routes an IGP over L2VPNs, with which device does the
remote CE router form an IGP adjacency?

A company wants to connect two data center sites using a hub-and-spoke design with 2000
remote sites. One design consideration is the requirement to transfer MPLS packets over the
public Internet. In addition, one router at each site should be used, and the MPLS packets must
be encapsulated inside IP packets because the public Internet cannot transfer native MPLS
packets. Which feature can be used to simplify the network design?

You are working on a network design plan for a company with approximately 2000 sites. The
sites will be connected using the public Internet. You plan to use private IP addressing in the
network design, which will be routed without NAT through an encrypted WAN network. Some
sites will be connected to the Internet with dynamic public IP addresses, and these addresses
may change occasionally. Which VPN solution will support these design requirements?
