BENEFITS OF HIERARCHICAL NETWORK DESIGN
The main benefit of the Three-Layer hierarchical model is that it helps to design, deploy and maintain a Scalable, trustworthy, cost-effective hierarchical inter-network.

What are three benefits of a hierarchical network model?
simplification of management and troubleshootingelimination of the need for wiring closetsincreased fault tolerance of the networkMore scalable it allows you to replicate the the design elements as the networks grows.

Which three features are commonly supported at the distribution layer of the Cisco hierarchical network model?

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 layer of the hierarchical three-layer design model combines traffic from multiple IDFs?
which layer of the hierarchical three-layer design model combines traffic from multiples IDFs? core layer
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
In a three-layer hierarchical network design which distribution layer function delineates broadcast domains?
routing between VLANs
Which three options correctly associate a layer of the hierarchical design model with its function?
Core, Distribution, and Access.
What is the highest layer of the OSI model used by router?
Router works in Network Layer of OSI model
What is true regarding network layer addressing?
The three correct options are: 3. Hierarchical Explanation: By design, layer three addressing is hierarchical, as you can group hosts in different networks. 4. Uniquely identifies each host Explanation: Each host has a unique address inside its network. 6. Contains a network portion Explanation: For example, in an IP (v4) address a portion of the most significant bits identify the network the host belongs to.1.It supports data communications between networks 2.It prevents broadcasts 3.It uniquely identifies each host
Why is layer three addressing hierarchical?
Layer 3 addressing is hierarchical because it allows the division of networks into subnets. For example, one route entry can refer to a large general network and another can refer to a subnet of that same network. When forwarding a packet, the router will select the most specific route that it knows. However, if a specific subnet is not in the routing table but the larger network that holds the subnet is known, then the router will send it to the larger network, trusting that another router will find the subnet.
