MCQ On Incremental Model

Q1. The Incremental Model develops software:.
  1. All at once
  2. In small parts (increments)
  3. Without planning
  4. Without testing

Answer: b, In small parts (increments)

Solution: The model divides development into multiple increments.

Q2. Each increment in the Incremental Model:.
  1. Is not tested
  2. Produces a working system
  3. Requires no requirements
  4. Is delivered only at the end

Answer: b, Produces a working system

Solution: Each increment delivers a functional module.

Q3. The Incremental Model combines features of:.
  1. Prototype + Spiral
  2. Waterfall + Iterative
  3. Agile + RAD
  4. V-Model + Spiral

Answer: b, Waterfall + Iterative

Solution: It uses Waterfall phases but in repeated cycles.

Q4. Which phase is repeated for every increment?.
  1. Requirement
  2. Design
  3. Coding and Testing
  4. All of the above

Answer: d, All of the above

Solution: Each increment goes through full SDLC phases.

Q5. A key advantage of the Incremental Model is:.
  1. No user involvement
  2. Early delivery of working software
  3. No planning needed
  4. Rigid structure

Answer: b, Early delivery of working software

Solution: User gets functional modules early.

Q6. The Incremental Model is suitable for:.
  1. Projects with unclear requirements
  2. Projects with fixed hardware
  3. Very small projects
  4. Projects requiring early partial deliveries

Answer: d, Projects requiring early partial deliveries

Solution: Best when early delivery is needed.

Q7. In Incremental Model, the first increment usually includes:.
  1. The most complex features
  2. The complete project
  3. The basic core functionality
  4. Only UI design

Answer: c, The basic core functionality

Solution: Core features are built first.

Q8. Customer feedback is incorporated:.
  1. Only at the end
  2. After each increment
  3. Only during coding
  4. Never

Answer: b, After each increment

Solution: Feedback shapes future increments.

Q9. Which is a disadvantage of the Incremental Model?.
  1. No early delivery
  2. Difficult to manage design changes
  3. Requires good planning and architecture
  4. No testing

Answer: c, Requires good planning and architecture

Solution: Poor architecture affects later increments.

Q10. Incremental development is:.
  1. Top-down
  2. Iterative + Sequential
  3. Random
  4. Parallel only

Answer: b, Iterative + Sequential

Solution: Uses waterfall steps iteratively.

Q11. A major benefit of the Incremental Model is:.
  1. Low testing coverage
  2. Late delivery
  3. Reduced impact of changes
  4. No user involvement

Answer: c, Reduced impact of changes

Solution: Small increments lower risk.

Q12. Incremental Model handles changing requirements:.
  1. Very poorly
  2. Only at the beginning
  3. Better than Waterfall
  4. Not at all

Answer: c, Better than Waterfall

Solution: Changes can be added in later increments.

Q13. Each increment is basically a:.
  1. Partial system
  2. Prototype
  3. Test case
  4. Deployment plan

Answer: a, Partial system

Solution: Each increment adds more functionality.

Q14. Which model delivers the complete system at once?.
  1. Incremental
  2. Waterfall
  3. Agile
  4. RAD

Answer: b, Waterfall

Solution: Waterfall delivers final system only at the end.

Q15. In the Incremental Model, which part is the MOST important?.
  1. Early delivery
  2. No documentation
  3. No meetings
  4. Skipping testing

Answer: a, Early delivery

Solution: Early usable software is key.

Q16. What is required before starting the Incremental Model?.
  1. Complete UI design
  2. Modular system architecture
  3. Fully working prototype
  4. No requirements

Answer: b, Modular system architecture

Solution: Modules should be clearly separable.

Q17. Testing in the Incremental Model is:.
  1. Done only once
  2. Done after each increment
  3. Not required
  4. Done only at the end

Answer: b, Done after each increment

Solution: Every increment is tested.

Q18. A risk of Incremental Model is:.
  1. No early feedback
  2. Too much customer involvement
  3. Architecture might break if not planned well
  4. No testing

Answer: c, Architecture might break if not planned well

Solution: Weak architecture causes failure in later increments.

Q19. Incremental Model is MOST similar to:.
  1. Spiral Model
  2. V-Model
  3. Iterative Model
  4. Prototype Model

Answer: c, Iterative Model

Solution: Incremental = iterative + partial delivery.

Q20. Which is NOT a feature of Incremental Model?.
  1. Delivers modules over time
  2. Allows partial implementation
  3. Requires good architecture
  4. Complete system delivered at once

Answer: d, Complete system delivered at once

Solution: Incremental delivers in parts.
