Need help for question 5 to question 12.

5. Assume the following: o An organizational unit has 2 database servers, 2 application servers, and 15 clients. o Database server performs data storage and data access logic. o Application server performs business (or application) logic. o One database server and one application server are used to address any client's request. Question: Such a client-server architecture would be typically classified as: a. 4-tier architecture (because there are four servers in this network). b. 5-tier architecture (because there are four servers and one client in the network). c. 3-tier architecture (because the database server, the application server, and the client each represent one tier respectively). d. n-tier architecture, where n=19 (because there are 19 computers in the network). True/False: (Clearly mark "True" or "False" on left margin). 6. Transmission media, circuits and channel are identical terms that have the same theoretical definitions. 7. According to some reports, the carbon footprint of data centers has exceeded the carbon footprint of the manufacturing industry and is on par (if not exceeded) the carbon footprint of the airline industry. 8. Microsoft Windows, Docker, and Kubernetes are examples of de jure standards. 9. Fiber optic cables have faster transmission rates, are less susceptible to corrosion, are lighter, and thinner when compared to twisted pair and coaxial cables. 10. Three vendors of virtualization technology include VMWare, Microsoft and Citrix. 11. Some issues relevant to data centers include location strategy, carbon footprint, design, utility costs, temperature, and security control of data centers. 12. The terms data striping and parity drive are related to RAID
