MCQ On Prototype Model

Q1. The Prototype Model is mainly used when:.
  1. Requirements are very clear
  2. Requirements are unclear or evolving
  3. Project is very small
  4. No user involvement is needed

Answer: b, Requirements are unclear or evolving

Solution: Prototype Model is ideal when requirements are unclear.

Q2. A prototype is:.
  1. The final working system
  2. A rough working model to gather requirements
  3. A testing tool
  4. A deployment version

Answer: b, A rough working model to gather requirements

Solution: Prototype helps users visualize early.

Q3. Which step comes first in the Prototype Model?.
  1. Final testing
  2. Quick design
  3. Build prototype
  4. Requirement gathering

Answer: d, Requirement gathering

Solution: Requirements are gathered first.

Q4. The main purpose of building a prototype is to:.
  1. Finish the project faster
  2. Clarify user requirements
  3. Replace the final product
  4. Enhance system performance

Answer: b, Clarify user requirements

Solution: Prototype clarifies requirements.

Q5. Prototype Model is best suited for:.
  1. Projects with stable requirements
  2. UI-heavy or interactive systems
  3. Projects with no user involvement
  4. Very large and stable systems

Answer: b, UI-heavy or interactive systems

Solution: Prototypes help visualize UI early.

Q6. Which of the following is NOT part of the Prototype Model?.
  1. Customer evaluation
  2. Quick design
  3. Risk analysis
  4. Refining requirements

Answer: c, Risk analysis

Solution: Risk analysis is part of Spiral Model.

Q7. After building the prototype, the next step is:.
  1. Final development
  2. Customer review
  3. Deployment
  4. Validation

Answer: b, Customer review

Solution: User reviews the prototype.

Q8. A disadvantage of the Prototype Model is:.
  1. Users get early working model
  2. Requirements can be clarified
  3. High development cost
  4. Early detection of errors

Answer: c, High development cost

Solution: Building multiple prototypes is costly.

Q9. The prototype is usually:.
  1. Fully functional
  2. Partially functional with limited features
  3. The final product
  4. A deployment tool

Answer: b, Partially functional with limited features

Solution: Prototype shows limited functionality.

Q10. The Prototype Model helps reduce:.
  1. Customer involvement
  2. Misunderstanding in requirements
  3. Testing time
  4. Deployment effort

Answer: b, Misunderstanding in requirements

Solution: Prototype reduces requirement confusion.

Q11. One major problem of Prototype Model is:.
  1. Slow delivery
  2. Users may think the prototype is the final system
  3. No user involvement
  4. No testing required

Answer: b, Users may think the prototype is the final system

Solution: Users may confuse prototype with final system.

Q12. Prototype Model is NOT suitable for:.
  1. Complex user-interactive systems
  2. Systems with unclear requirements
  3. Stable and well-defined projects
  4. Research-based projects

Answer: c, Stable and well-defined projects

Solution: Prototype is unnecessary for stable requirements.

Q13. Which is the correct sequence in Prototype Model?.
  1. Build prototype -> Quick design -> Requirement
  2. Requirement -> Quick design -> Build prototype -> Review
  3. Requirement -> Build prototype -> Review -> Quick design
  4. Deployment -> Prototype -> Review

Answer: b, Requirement -> Quick design -> Build prototype -> Review

Solution: This is the correct order.

Q14. Prototype is mainly used for:.
  1. Improving documentation
  2. User interface validation
  3. Coding optimization
  4. System maintenance

Answer: b, User interface validation

Solution: Prototype helps validate UI early.

Q15. Which model allows customer feedback very early?.
  1. Waterfall
  2. V-Model
  3. Prototype Model
  4. Spiral Model

Answer: c, Prototype Model

Solution: Prototype includes early review.

Q16. Which type of prototype is thrown away after use?.
  1. Evolutionary
  2. Incremental
  3. Throwaway prototype
  4. Spiral prototype

Answer: c, Throwaway prototype

Solution: Throwaway prototype is discarded.

Q17. The final system is developed:.
  1. Immediately after requirement gathering
  2. After refining requirements using the prototype
  3. Without customer involvement
  4. Before creating a prototype

Answer: b, After refining requirements using the prototype

Solution: Requirements are refined first.

Q18. Prototype Model reduces:.
  1. Deployment cost
  2. Communication gap between users and developers
  3. Testing time
  4. Documentation effort

Answer: b, Communication gap between users and developers

Solution: Prototype improves communication.

Q19. Prototype Model helps identify:.
  1. Exact coding errors
  2. Performance issues
  3. Misunderstood or missing requirements
  4. Database errors

Answer: c, Misunderstood or missing requirements

Solution: Prototype clarifies missing requirements.

Q20. The biggest advantage of Prototype Model is:.
  1. No rework
  2. Improves requirement clarity
  3. Saves time always
  4. No customer involvement

Answer: b, Improves requirement clarity

Solution: Better requirement understanding is the main advantage.
