Refer to the exhibit.In this network design, where should summarization occur to provide the best summarization
and optimal paths during a single-failure incident as well as during normal operation?

When you design a network, when would it be required to leak routes into a Level 1 area?

Which three techniques can be used to improve fault isolation in an enterprise network design?
(Choose three.)

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

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

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

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?

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?

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.)

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?
