Question 2

Information systems that monitor the elementary activities and transactions of the organizations are:
A)Management-level system
B)Operational-level system
C)Knowledge-level system
D)Strategic level system

Accepted Answer

Operational-level systems are designed to monitor the day-to-day operations and transactions of an organization, such as sales, receipts, cash deposits, payroll, credit decisions, and the flow of materials in a factory.

Question 3

Projections and responses to queries are information output characteristics associated with a(n):
A)DSS
B)MIS
C)ESS
D)TPS

Accepted Answer

C

Question 4

Summary transaction data, high-volume data, and simple models are information inputs characteristic of a(n):
A)DSS
B)MIS
C)ESS
D)TPS

Accepted Answer

Summary transaction data, high-volume data, and simple models are information inputs characteristic of a TPS (Transaction Processing System). TPSs are designed to process large volumes of routine transactions, such as sales orders, invoices, and payments. They typically use simple models to ensure that transactions are processed accurately and efficiently.

Question 7

When should a risk be avoided?
A)When the risk event has a low probability of occurrence and low impact
B)When the risk event is unacceptable -- generally one with a very high probability of occurrence and high impact
C)When it can be transferred by purchasing insurance
D)none

Accepted Answer

The answer of When should a risk be avoided?
A)When the...

Question 8

An example of risk mitigation is:
A)Using proven technology in the development of a product to lessen the probability that the product will not work
B)Purchasing insurance
C)Accepting a lower profit if costs overrun
D)a and b

Accepted Answer

Risk mitigation involves strategies to reduce and manage risks. Using proven technology can decrease the likelihood of product failure, and purchasing insurance can protect against financial losses, both of which are examples of risk mitigation strategies.

Question 9

Mitigating risk could involve
A)identifying risks, obtaining insurance and developing alternatives
B)contracting and quality assurance
C)developing standards, buying insurance, and planning for contingencies and
D)re-scoping the project and reassessing requirements

Accepted Answer

The answer of Mitigating risk could involve
A)identifying risks, obtaining insurance...

Question 10

The linear sequential model of software development is
A)A reasonable approach when requirements are well defined.
B)A good approach when a working program is required quickly.
C)The best approach to use for projects with large development teams.
D)An old-fashioned model that cannot be used in a modern context.

Accepted Answer

The linear sequential model, also known as the waterfall model, is most effective when requirements are well defined from the beginning. This model follows a sequential order, making it less flexible but suitable for projects with clear objectives and stable requirements.

Question 11

The linear sequential model of software development is also known as the
A)Classical life cycle model
B)Fountain model
C)Spiral model
D)Waterfall model

Accepted Answer

The linear sequential model of software development is also known as the Waterfall model.

Question 12

The incremental model of software development is
A)A reasonable approach when requirements are well defined.
B)A good approach when a working core product is required quickly.
C)The best approach to use for projects with large development teams.
D)A revolutionary model that is not used for commercial products.

Accepted Answer

The incremental model allows for parts of the solution to be developed and delivered incrementally, which is beneficial when a core product needs to be launched quickly, allowing for further development and iterations based on feedback or additional requirements.

Question 13

The rapid application development model is
A)Another name for component-based development.
B)A useful approach when a customer cannot define requirements clearly.
C)A high-speed adaptation of the linear sequential model.
D)All of the above.

Accepted Answer

The rapid application development (RAD) model is a high-speed adaptation of the linear sequential model, focusing on quick development and iteration.

Question 14

Evolutionary software process models
A)Are iterative in nature
B)Can easily accommodate product requirements changes
C)Do not generally produce throwaway systems
D)All of the above

Accepted Answer

Evolutionary software process models are iterative, allowing for continuous refinement and adaptation, which makes them flexible in accommodating changes in product requirements. They aim to evolve a final system through incremental development, thus not generally producing throwaway systems but rather improving upon each version.

Question 15

The prototyping model of software development is
A)A reasonable approach when requirements are well defined.
B)A useful approach when a customer cannot define requirements clearly.
C)The best approach to use for projects with large development teams.
D)A risky model that rarely produces a meaningful product.

Accepted Answer

The prototyping model is particularly useful when requirements are not clear. It allows for the development of a working model that can be evaluated and refined, helping both developers and customers to explore and define requirements more effectively.

Question 16

The spiral model of software development
A)Ends with the delivery of the software product
B)Is more chaotic than the incremental model
C)Includes project risks evaluation during each iteration
D)All of the above

Accepted Answer

The spiral model incorporates risk analysis and mitigation strategies at each phase of development, distinguishing it from other models by continuously addressing potential risks throughout the project lifecycle.

Question 17

The concurrent development model is
A)Another name for the rapid application development model.
B)Often used for the development of client/server applications.
C)Only used for development of parallel or distributed systems.
D)Used whenever a large number of change requests are anticipated.

Accepted Answer

The answer of The concurrent development model is
A)Another name for...

Question 18

The component-based development model is
A)Only appropriate for computer hardware design.
B)Not able to support the development of reusable components.
C)Works best when object technologies are available for support.
D)Not cost effective by known quantifiable software metrics.

Accepted Answer

The component-based development model leverages reusable components and is most effective when supported by object-oriented technologies, which facilitate the encapsulation of data and functionality, making it easier to design, develop, and maintain software by reusing existing components.

Question 19

The formal methods model of software development makes use of mathematical methods to
A)Develop defect free computer-based systems
B)Define the specification for computer-based systems
C)Verify the correctness of computer-based systems
D)All of the above
