What is hierarchical network design?
A hierarchical network design involves dividing the network into discrete layers. Each layer, or tier, in the hierarchy provides specific functions that define its role within the overall network.What are four benefits of hierarchical network design?
Hierarchical networks branch network connections between departments and users simply and logically. Hierarchical network design provides efficient, fast and logical traffic forwarding patterns for enterprise network topologies while minimizing the cost of connecting multiple devices at network endpoints.What are the layers of hierarchical design model?
The Hierarchical internetworking model is a three-layer model for network design first proposed by Cisco. It divides enterprise networks into three layers: core, distribution, and access layer.- Cisco's 3 Layered model consist from the core, the distribution and the access layers. The Core layer is actually the backbone, or the core, of your network. This is the most critical layer because its purpose is to provide fault isolation and backbone connectivity.

5Manageability
Consistency between switches at each level
makes management more easierMaintainability
The modularity of hierarchical design allows for
the network to scale without becoming overly complicated 6 2Access Layer Switches
Power over Ethernet (PoE)
Allows the switch to deliver power to a device
over the existing Ethernet cabling. Used by IP phones and some wireless access points.It adds considerabl
y to the cost of the switch. 7 yLink aggregation
Cisco's EtherChannel technology allows a group
of physical Ethernet links to create one logicalEthernet link for the purpose of providing fault
tolerance and high-speed links between switches, routers, and servers. 8Distribution Layer Switch Features
Inter-VLAN routing is performed at the distribution layer. Multilayer switches support Layer 3 functions.Security Policies - Access control lists (ACLs)
