Introducing Network Design Concepts
Explain How a Hierarchical Network Design Creates a Stable, Reliable, Scalable Network
Network requirements :
-Ease of management
-Fast recovery
-Application response time
-Fast troubleshooting
Four fundamental network design goals
-Scalability
-Availability
-Security
-Manageability
-Core Layer = connects Distribution Layer devices
-Distribution Layer = interconnects smaller LANs
-Access Layer = provides connections for hosts and end devices
three-layer model
-Enterprise campus
-Server farm
-Enterprise edge
Advantages of Modular Framework
-It provides scalability
-It creates a deterministic network with clearly
Explain what Factors Need to be Considered when Designing the Network Core Layer
-Redundancy and load balancing
-Quick convergence
-Network backbone
-Full mesh topology
-Partial mesh topology
-Failure prevention
-Reducing human error
Explain which Factors Need to be Considered when Designing the Distribution Layer of a Network
-Route summarization
-Routing between VLANs
-Access control policies
Explain which Factors Need to be Considered when Designing the Access Layer of a Network
-Physical location of equipment
-Wiring closets
-Converged networking
-Availability
Functions of VLANs
-Separate and classify traffic
-Control broadcasts
-Contain VLANs within a single wiring closet
