Models & Software Development MCQs

The spiral model has two dimensions namely _______________ and _______________?

by
A. diagonal, angular
B. radial, perpendicular
C. radial, angular
D. diagonal, perpendicular
✅ The correct answer is option C.
Explanation: The radial dimension of the model represents the cumulative costs and the angular dimension represents the progress made in completing each cycle. Each loop of the spiral from X-axis clockwise through 360o represents one phase.

What is the major advantage of using Incremental Model ?

by
A. Customer can respond to each increment
B. Easier to test and debug
C. It is used when there is a need to get a product to the market early
D. Easier to test and debug & It is used when there is a need to get a product to the market early
✅ The correct answer is option D.
Explanation: Incremental Model is generally easier to test and debug than other methods of software development because relatively smaller changes are made during each iteration and is popular particularly when we have to quickly deliver a limited functionality system.However, option “a” can be seen in other models as well like RAD model,hence option “d” answers the question.

Which of the following life cycle model can be chosen if the development team has less experience on similar projects ?

by
A. Spiral
B. Waterfall
C. RAD
D. Iterative Enhancement Model
✅ The correct answer is option A.
Explanation: Relying on risk assessment/analysis provides more flexibility than required for many applications which overcomes the criteria of less experienced developers.

Four types of change are encountered during the support phase . Which one of the following is not one that falls into such category ?

by
A. Translation
B. Correction
C. Adaptation
D. Prevention
✅ The correct answer is option A.
Explanation: Translation is done in the development phase.
