Question

1. (TCO 2) Which of the following is an example of a tangible benefit? (Points : 2) Improved customer goodwill Reduced credit losses Improved employee morale Better decision making None of the above

Question 2. 2. (TCO 2) The cost of the ability to invest in alternative projects rather than the project under consideration is known as (Points : 2) opportunity cost. investment cost. discount cost. present cost. None of the above

Question 3. 3. (TCO 2) Costs that occur in proportion to some usage factor are known as (Points : 2) variable. tangible. intangible. fixed. None of the above

Question 4. 4. (TCO 2) When determining the cost-effectiveness of a project, which of the following is an important concept to understand? (Points : 2) The feelings of the end users about their role in the system Whether we currently possess the necessary technology The time value of money Whether the system offers adequate controls against embezzlement and fraud All of the above

Question 5. 5. (TCO 2) Benefits that can be easily quantified are known as (Points : 2) variable. tangible. intangible. fixed. None of the above

Question 6. 6. (TCO 6) What defines the technologies to be used by (and used to build) one, more, or all information systems in terms of their data, processes, interfaces, and network components? (Points : 2) Rapid application development Object-oriented design Application architecture Prototyping None of the above

Question 7. 7. (TCO 6) Which of the following is a disadvantage of prototyping? (Points : 2) Prototyping encourages a return to the "code, implement, and repair" life cycle. Prototypes are a passive model of the system. End users don't fully understand their requirements until they see them implemented. Errors cannot be detected as easily when a prototype is developed. None of the above

Question 8. 8. (TCO 6) Which technique emphasizes the participative development among system owners, users, designers, and builders? (Points : 2) Rapid application development Joint application development Application architecture Both rapid application development and joint application development None of the above

Question 9. 9. (TCO 6) Which of the following is a disadvantage of prototyping? (Points : 2) Numerous design issues are not addressed by prototyping. Prototyping does not negate the need for systems analysis phases. The scope and complexity of the system can quickly get out of control. A prototype cannot completely substitute for a paper specification. All of the above

Question 10. 10. (TCO 6) Which of the following is an advantage of prototyping? (Points : 2) Prototypes are an active, not passive, model that end users can see, touch, feel, and experience. Prototyping can increase creativity because it allows for quicker user feedback, which can lead to better solutions. Prototyping accelerates several phases of the life cycle. Iteration and change are a natural consequence of systems development. Prototyping better fits this natural situation because it assumes that a prototype evolves. All of the above

Question 11. 11. (TCO 6) A system in which the components of an information system are distributed to multiple locations in a computer network is known as (Points : 2) a centralized system. an emulated system. a database system. a communications system. None of the above

Question 12. 12. (TCO 6) Which of the following is NOT represented as a physical data store? (Points : 2) A database A table in a database A computer file A transport protocol A tape or media backup of temporary files or anything important

Question 13. 13. (TCO 6) The information system application layer that includes all the logic and processing required to support the actual business application and rules is known as (Points : 2) the presentation layer. the presentation logic layer. the application logic layer. the data manipulation layer. the data layer.

Question 14. 14. (TCO 6) The application architectural blueprint communicates which of the following design decisions? (Points : 2) The distribution of stored data across a network The technology to be used to interface with other systems The technology to be used to implement the user interface The integration of any commercial off-the-shelf software All of the above

Question 15. 15. (TCO 6) A set of computers connected over a relatively short distance to one or more servers is known as a(n) (Points : 2) LAN. WAN. MAN. CAN. backbone.
