CCNA3 Exploration Chapter 1. Study questions. 1. What are the three layers of the hierarchical network design model? 2. What are the advantages of designing LANs using the hierarchical
model?

3.What is the purpose of the access layer? 4. What sort of devices are found at the access layer? 5. What is the purpose of the distribution layer? 6. What sort of devices are found at the distributionlayer? 7. What is the purpose of the core layer? 8. What is a collapsed core model and where might it be used? 9. What is a wiring closet? 10. Why is it not easy to see the logical hierarchical designof a network

when looking at the network layout in a building? 11. Why is redundancy important in a network? 12. Which layers normally have redundancy built in? 13. How can the hierarchical designhelp to give high performance? 14. How can switches at the different layers contribute to network security? 15. How does a hierarchical design help to make a network manageable? 16. Should the sametype of switch be used at each layer of the hierarchical design? 17. What is “network diameter” in hierarchical network design? 18. What is network device latency? 19. What sort of processing does aswitch have to do on each packet? 20. How can bandwidth aggregation be implemented? 21. Why is redundancy not normally provided at the access layer? 22. When designing a new network, at which layerwould you start? 23. What is a converged network? 24. What factors have slowed the move towards converged networks? 25. What are the benefits of a converged network? 26. Why was videoconferencingequipment originally kept on a separate network from data or phones, and what made it possible to combine videoconferencing with other networks? 27. What is traffic flow analysis, and why might you want to doit? 28. How can measurements be made in order to carry out a traffic flow analysis? 29. How can a User Communities Analysis help with network design? 30. Which two types of traffic need to be...
