A). Rapid Application Document

B). Rapid Application Development

C). Relative Application Development

D). None of these

Show explanation Expand Question

RAD stands for Rapid Application Development.

Question 32

The spiral model of software development _____?

A). Includes project risks evaluation during each iteration

B). Is more chaotic than the incremental model

C). Ends with the delivery of the software product

D). All of the above

Show explanation Expand Question

The spiral model includes risk evaluation at each iteration and ends with product delivery, covering all options.

Question 33

Identify the disadvantage of Spiral Model.

A). High amount of risk analysis

B). Additional Functionality can be added at a later date

C). Doesn’t work well for smaller projects

D). Strong approval and documentation control

Show explanation Expand Question

Spiral Model does not work well for smaller projects due to its complexity.

Question 34

Which property of the rapid prototype is not important?

A). The speed with which it can be developed

B). The speed with which it can be modified

C). Its ability to determine the client’s real needs

D). The insights that the design team can gain from it, even if they are of the ‘how not to do it’ variety

Show explanation Expand Question

Determining the client’s real needs is important, so the least important among the listed properties is option C.

Question 35

What is the major drawback of using RAD Model?

A). Increases reusability of components

B). Increases reusability of components, Highly specialized & skilled developers/designers are required

C). Encourages customer/client feedback

D). Highly specialized & skilled developers/designers are required

Show explanation Expand Question

RAD requires highly specialized and skilled developers/designers, making it a drawback.

Question 36

A). Spiral modeling

B). Waterfall modeling

C). Iterative modeling

D). None of these

Show explanation Expand Question

This describes iterative modeling, where the system is continually revised.

Question 39

The major shortcoming of waterfall model is _____?

A). The difficulty in accommodating changes after requirement analysis

B). The system testing

C). The difficult in accommodating changes after feasibility analysis

D). The maintenance of system

Show explanation Expand Question

Waterfall model struggles to accommodate changes after requirement analysis.

Question 40

With regard to Evolutionary development model, identify the correct statement.

A). Often the construction of a throw-away prototype is not followed by a reimplementation of the system using a more structured approach.

B). Exploratory development is used in situations where most of the requirements are well understood in advance

C). Evolutionary development usually comes in two flavors; exploratory development, and throw-away prototyping

D). One of the strong points of evolutionary development is that it facilitates easy project management, through the high volume of documentation it generates

Show explanation Expand Question

Evolutionary development has two flavors: exploratory development and throw-away prototyping.
