1. Which of the following is NOT one of the four basic functions of a computer
application? (D) networking logic
2. A server can be a (B) mainframe, minicomputer or microcomputer.
3. The function that allows data to be stored and retrieved is called (B) data access
logic.
4. A sever in the client-server architecture performs which of the following
application functions? (D) data access logic and data storage
5. What is the primary problem with server-based computer architectures? (A) As
more users place heavier demands on the server, it is expensive to increase
server capacity.
6. Scalability refers to the (A) easy increase or decrease of the storage and
processing capabilities of the computer.
7. In an n-tiered architecture, the (B) application logic is spread across two or more
different sets of servers.
8. Which of the following is the general term for the middleware between the clients
and the servers? (A) DOC
9. The six characteristics that assist in selecting the proper architecture are: cost of
infrastructure, cost of development, ease of development, (C) interface
capabilities, control and security, scalability.
10. 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.
With this growth, many new employees will surely be hired and trained. He has
received a large amount of money from a small business grant for the initial
development. 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.

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

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
