Which layer of the hierarchical network design model is referred to as the high speed backbone of the internetwork where high availability and redundancy are critical?
core layer
What are the 3 layers of the cisco hierarchical model?
From a network design standpoint: Core Distribution Access
Which hierarchical design characteristic would be recommended at both the core and distribution layers to protect the network in the case of a route failure?
The core layer is critical for interconnectivity between distribution layer devices, so it is important for the core to be highly available and redundant, so redundancy is the answer.
Which layer of the hierarchical design model provides a means of connecting devices to the network and controlling which devices are allowed to communicate on the network?
distribution
What are the three benefits of hierarchical network model?
Reduced content for bandwidth Increased fault tolerance of the network Simplification of management and troubleshooting
In a three-layer hierarchical network design which distribution layer function delineates broadcast domains?
routing between VLANs

What are the three layers of the hierarchical network design model?
A hierarchical network design includes the following three layers:The backbone (core) layer that provides optimal transport between sitesThe distribution layer that provides policy-based connectivityThe local-access layer that provides workgroup/user access to the networkhttp://docwiki.cisco.com/wiki/Internetwork_Design_Guide_--_Internetworking_Design_Basics#Function_of_the_Access_Layer
What does The DeVry Advantage Academy specialize in?
Network Systems Administration & Web Graphic Design
What are three benefits of employing a hierarchical network design?
Hierarchically designed networks can more easily be expanded to suit future needs.Hierarchical design models enhance existing bandwidth through the use of link aggregation.The hierarchical model allows for specialized functionality at each layer, simplifying device management
Which hierarchical design model layer controls the flow of network traffic using policies and delineates broadcast domains by performing routing functions between virtual LANs?
distribution
