1881. Which of the following is not an option to achieve reliable cost and effort estimate ?

by
A. Base estimates on similar projects that have already been completed
B. Use one or more empirical models for software cost and effort estimation
C. Use relatively simple decomposition techniques to generate project cost and effort estimates
D. The ability to translate the size estimate into human effort, calendar time, and dollars
✅ The correct answer is option D.

1882. Which of the following is a category of a stimuli ?

by
A. Periodic stimuli
B. Software stimuli
C. Hardware stimuli
D. Management stimuli
✅ The correct answer is option A.
Explanation: Periodic stimuli occur at predictable time intervals. For example, the system may examine a sensor every 50 milliseconds and take action depending on that sensor value.

1883. Which of the following is a project scheduling method that can be applied to software development ?

by
A. PERT
B. CPM
C. CMM
D. Both PERT and CPM
✅ The correct answer is option D.
Explanation: Program evaluation and review technique (PERT) and critical path method (CPM) are two project scheduling methods that can be applied to software development.

1887. In the Analysis phase, the development of the ______________ occurs, which is a clear statement of the goals and objectives of the project ?

by
A. documentation
B. flowchart
C. program specification
D. design
✅ The correct answer is option C.
Explanation: Program specification is the definition of what a computer program is expected to do.

1890. Which pattern prevents one from creating more than one instance of a variable ?

by
A. Factory Method
B. Singleton
C. Observer
D. None of the mentioned
✅ The correct answer is option B.
Explanation: In singleton pattern, the class itself is made responsible for keeping track of its instance.Thus it ensures that no more than one instance is created.
