1)!Describe!the!Hierarchical!Network!Model?!Describe!the!benefits!of!the!
Hierarchical!Network!Model.!
!
Ans:!!
!
This!model!simplifies!the!task!of!building!a!reliable,!scalable,!and!less!expensive!hierarchical!
internetwork!because!rather!than!focusing!on!packet!construction,!it!focuses!on!the!three! functional!areas,!or!layers,!of!your!network:! !
Core!layer:!This!layer!is!considered!the!backbone!of!the!network!and!includes!the!highFend!
switches!and!highFspeed!cables!such!as!fiber!cables.!This!layer!of!the!network!does!not!route! traffic!at!the!LAN.!In!addition,!there!is!no!packet!manipulation!that!is!done!by!devices!in!this! layer.!Rather,!this!layer!is!concerned!with!speed!and!ensures!reliable!delivery!of!packets.!
!
Distribution!layer:!This!layer!includes!LANFbased!routers!and!layer!3!switches.!This!layer! ensures!that!packets!are!properly!routed!between!subnets!and!VLANs!in!your!enterprise.!This! layer!is!also!called!the!Workgroup!layer.!
!
Access!layer:!This!layer!includes!hubs!and!switches.!This!layer!is!also!called!the!desktop!layer! because!it!focuses!on!connecting!client!nodes,!such!as!workstations!to!the!network.!This!layer! ensures!that!packets!are!delivered!to!end!user!computers.!

!
When!we!implement!these!layers,!each!layer!might!comprise!more!than!two!devices!or!a!single!
device!might!function!across!multiple!layers.!The!benefits!of!the!hierarchical!model!include:!
