Ethan is considering the replacement of the existing network for his organization. He has projected organizational growth at 50% per year for the next five years.

The architecture Ethan should select is (C) client-sever. 11. A network model will depict (B) network equipment. 12. Elements of a deployment diagram include, (E) nodes, artifacts and communication paths. 13. Which one of the following type of operational requirements attempts to anticipate the future requirements? (D) Maintainability requirements. 14. Which of the following is not part of the security requirements? (B) Capacity requirements. The output grade for this quiz is 93% which is good enough for me at 3am. Karma points if you find my mistakes and tell me. Chapter 12 – Physical Architecture Layer Design 15. In the public key – private key encryption algorithm, normally the public key is used to (A) encrypt the data, while the private key is used to decrypt the data. 16. The public key infrastructure (PKI) is (E) all of the above. – hardware, software, organizations, policies. 17. Recent studies have shown that almost (A) 90 percent of organizations suffer a virus infection each year. 18. Recent studies have show that almost (A) 90 percent of organizations suffer a virus infection each year. 19. Systems designed to handle multiple languages on the fly are (B) concurrent multilingual systems. 20. Many countries have (E) unstated norms for expressing information such as dates that are unique to the counties. Knowledge of these norms is important when developing global information systems. 21. Client-server architectures strive to balance the processing between the client and the server by having both perform some of the application functions. TRUE 22. A three-tiered architecture uses only three sets of computers, clients, database, severs and application servers. TRUE 23. Senior management has established the priority for the new system as “user friendly, and quickly and inexpensively expandable to all parts of the organization.” The systems analyst should recommend a client-sever based computing architecture. TRUE 24. Sever-based computer required a high degree of coordination among many components, and the chances of holes in security or other control problems are much greater than with client-sever computer. FALSE 25. The purpose of the network model is to convey the complexity of the system, to show how the system’s components will fit together, and to help the project team develop the hardware and software specification. TRUE 26. In a deployment diagram, typically a node is labeled with a stereotype, with the stereotype representing the type of node e.g., webserver, database sever, mobile device). TRUE 27. A discrete multilingual system is one that contains separate parts that are written in each language and must be reinstalled before a specific language can be used. TRUE The output grade for this quiz is 93% which is good enough for me at 3am. Karma points if you find my mistakes and tell me. Chapter 12 – Physical Architecture Layer Design 28. Most systems are not built to use the existing infrastructure in the organization, so the current infrastructure rarely restricts the choice of architecture. FALSE 29. The client-sever architecture is much easier to administer because all data are stored in a single location. TRUE 30. The function that provides the processing logic required by the human-computer interaction layer is called application logic. TRUE 31. In a deployment diagram, a communication path represents a communication link between the nodes of the physical architecture. TRUE 32. Communication paths may be stereotyped. TRUE 33. Availability requirements, which are one kind of performance requirement, attempt to predict how fast the system should operate. FALSE 34. Speed requirements, which are one kind of performance requirement, attempt to predict how many total and simultaneous users the system will need to support at full-speed. FALSE 35. “The system should be operational on a 24/7 basis for the users.” This is an example of a capacity requirement. FALSE 36. Minicomputer typically costs thousands of dollars while a mainframe costs hundreds of thousands of dollars. FALSE 37. Encryption and authentication requirements address security requirements. TRUE 38. The languages in which the system needs to operate are documents as part of the customization requirements. FALSE 39. Maintainability an access control requirements are better met by the client-sever architectures than the sever-based architectures. FALSE 40. Client-based systems are ill equipped to meet operational, performance, security, and cultural/political requirements. FALSE 41. A sever in the client-server architecture performs applications logic, data access logic, data storage, and presentation logic. FALSE 42. Assume that your network has two application servers, a database sever and thirty-three clients; this network is an example of a four-tiered architecture. FALSE The output grade for this quiz is 93% which is good enough for me at 3am. Karma points if you find my mistakes and tell me. Chapter 12 – Physical Architecture Layer Design 43. Scalability is an important attribute in today’s systems. Client-based architectures tend to be more scalable compared to client-server architectures. FALSE 44. In order to prepare computer systems for global communication, concurrent multilingual systems contain spate parts that are written in multiple languages and must have each language reinstalled before is can be used. FALSE 45. Legacy databases and systems are one of sever factors in the hardware and software specification document. TRUE 46. Cost of ownership is an estimate of the cost of maintenance of the system. TRUE The output grade for this quiz is 93% which is good enough for me at 3am. Karma points if you find my mistakes and tell me.
