Software Engineering MCQs

1. What is the main characteristic of the Waterfall model?

a) Cyclical development b) Phases must be completed sequentially c) Rapid prototyping d) High flexibility

2. Which phase comes first in the Waterfall model?

a) Design b) Coding c) Testing d) Requirements gathering

3. What is a major drawback of the Waterfall model?

a) It’s too fast b) Difficult to accommodate changes c) No need for documentation d) High testing costs

4. What does the prototyping model emphasize?

a) Skipping testing b) Building a working prototype early c) Delivering software in a single release d) Avoiding customer feedback

5. When is the prototyping model most useful?

a) When requirements are clear b) For very small projects c) When requirements are uncertain or evolving d) For high-risk projects

6. What is the main goal of a prototype?

a) To act as the final product b) To replace documentation c) To validate requirements and get feedback d) To avoid the design phase

7. Which model is best for high-risk, complex projects?

a) Waterfall b) Incremental c) Spiral d) Agile

8. What is a key feature of the Spiral model?

a) Skipping testing phases b) Repeating cycles with risk analysis c) No need for user feedback d) Fixed, unchangeable requirements

9. What happens at the end of each Spiral cycle?

a) A new prototype is built b) A risk assessment is conducted c) The project is deployed d) The product is finalized

10. Which model is least suited for rapid development?

a) Spiral b) Waterfall c) Prototyping d) Incremental

11. How does the Spiral model handle evolving requirements?

a) It ignores changes b) It restarts from scratch c) It adapts in each iteration d) It locks requirements early

12. Which model is the simplest to manage?

a) Spiral b)Waterfall c) Prototyping d) Agile

13. What is a limitation of the prototyping model?

a) It’s too rigid b) It requires excessive documentation c) It may lead to scope creep d) It lacks user involvement

14. Which model balances flexibility with risk management?

a) Waterfall b) Agile c) Spiral d) V-Model

15. Which model would you choose for a small, well-defined project?

a) Spiral b) Prototyping c) Waterfall d) Incremental
