You have created a network design that has two point-to-point Metro Ethernet circuits extending a
single production VLAN between two data centers. Under normal circumstances, one circuit will
carry traffic and spanning tree will block the other. If the company wants you to make use of both
circuits to carry production traffic, which two technologies and features will you investigate to
integrate into your network design? (Choose two.)

Voice traffic between two campus enterprise networks is growing. The network designers decide
to add a second 10-Mb Metro Ethernet service parallel to their original 10-Mb service in order to
provide more bandwidth and diversity. The QoS profile will be the same on the new 10-Mb service
due to the voice stability on the first Metro Ethernet link. When the second link is added to the
OSPF domain, which traffic design consideration would have the most impact on the voice traffic
when both links are active?

You work as a network designer for a company that is replacing their Frame Relay WAN with an
MPLS VPN service, where the PE-to-CE routing protocol is BGP. The company has 3000 routes
in their distribution routers, and they would like to advertise their access routers through the MPLS
network. Their service provider, however, only supports 1000 prefixes per VRF. Which two design
solutions can be applied to ensure that your access routers will be able to reach all devices in your
network? (Choose two.)

You are designing a network that will run EIGRP over a Metro Ethernet service that does not
employ a link-loss technology. What will be the impact on convergence if there is a break in the
end-to-end Layer 2 connectivity within the service provider network?

Refer to the exhibit.

Acme Corporation hired you as a network designer to upgrade their network so that it supports
IPv4 and IPv6 multicast. Which two protocols are needed on the LAN switch? (Choose two.)

A new video multicast application is deployed in the network. The application team wants to use
the 239.0.0.1 multicast group to stream the video to users. They want to know if this choice will
impact the existing multicast design. What impact will their choice have on the existing multicast
design?

A customer is using a service provider to provide a WAN backbone for a 30-site network. In
establishing the network, the customer must work within these constraints:
The customer has a self-managed MPLS backbone.
The VPLS WAN backbone of the service provider does not support PIM snooping.
Multicast VPN must be used for multicast support inside some VRFs.
What can the customer do so that multicast traffic is NOT flooded to all sites?

What are two design advantages to using virtual port channel? (Choose two.)

Refer to the exhibit.

In this design, which technology would provide for the best use of resources to provide end-to-end
Layer 2 connectivity?

What are three key design principles when using a classic hierarchical network model? (Choose
three.)
