Answer: a, Rapid Application Development

Solution: RAD stands for Rapid Application Development.

Q2. RAD Model emphasizes:.
  1. Slow and careful planning
  2. Quick development and delivery
  3. Heavy documentation
  4. No user involvement

Answer: b, Quick development and delivery

Solution: RAD focuses on rapid development and fast delivery.

Q3. RAD is most suitable when:.
  1. Requirements are unclear
  2. Requirements are fixed and stable
  3. Project is very large and complex
  4. Users are unavailable

Answer: a, Requirements are unclear

Solution: RAD works best when requirements evolve with feedback.

Q4. Which of the following is a key concept in RAD?.
  1. Reusability of components
  2. Strict phase completion
  3. No prototyping
  4. Waterfall-style flow

Answer: a, Reusability of components

Solution: RAD encourages use of reusable components.

Q5. RAD uses:.
  1. Long development cycles
  2. Time-boxed development phases
  3. Only manual coding
  4. Heavy risk analysis

Answer: b, Time-boxed development phases

Solution: RAD uses short, fixed-duration development cycles.

Q6. Which of the following is NOT a phase in RAD?.
  1. Requirements Planning
  2. User Design
  3. Rapid Construction
  4. Risk Analysis

Answer: d, Risk Analysis

Solution: Risk analysis is part of the Spiral Model, not RAD.

Q7. Continuous customer involvement occurs in which RAD phase?.
  1. Rapid Construction
  2. User Design
  3. Cutover
  4. Deployment

Answer: b, User Design

Solution: User Design phase involves feedback through prototypes.

Q8. RAD Model uses prototypes to:.
  1. Replace final software
  2. Clarify requirements
  3. Increase documentation
  4. Reduce testing

Answer: b, Clarify requirements

Solution: Prototypes help refine user requirements.

Q9. What is the final phase of the RAD Model?.
  1. Requirements Planning
  2. User Design
  3. Rapid Construction
  4. Cutover

Answer: d, Cutover

Solution: Cutover includes testing, training, and deployment.

Q10. Which factor makes RAD successful?.
  1. Skilled developers
  2. Lack of user involvement
  3. Long testing cycles
  4. Sequential development

Answer: a, Skilled developers

Solution: RAD requires skilled teams for rapid development.

Q11. A disadvantage of RAD is:.
  1. Too much documentation
  2. Requires constant user involvement
  3. Very slow development
  4. Cannot handle UI-heavy apps

Answer: b, Requires constant user involvement

Solution: RAD requires continuous involvement from end users.

Q12. RAD is NOT suitable for:.
  1. Large and complex projects
  2. UI-based apps
  3. Time-sensitive applications
  4. Projects with evolving requirements

Answer: a, Large and complex projects

Solution: RAD is not effective for very large projects.

Q13. Which of the following best describes RAD?.
  1. Build fast, review fast, improve fast
  2. Build once, review once
  3. Document first, code later
  4. Complete planning before coding

Answer: a, Build fast, review fast, improve fast

Solution: RAD focuses on quick prototyping cycles.

Q14. Which tool type is often used in RAD?.
  1. CASE tools
  2. Assemblers
  3. Compilers only
  4. Reverse engineering tools

Answer: a, CASE tools

Solution: CASE tools help automate development tasks.

Q15. RAD encourages:.
  1. Minimal end-user involvement
  2. Early and frequent prototype demonstrations
  3. Delayed testing
  4. One final release only

Answer: b, Early and frequent prototype demonstrations

Solution: Frequent prototype reviews are central to RAD.

Q16. In RAD, requirements are refined:.
  1. Only at the beginning
  2. After deployment
  3. Throughout the development using prototypes
  4. Never

Answer: c, Throughout the development using prototypes

Solution: Requirements evolve via user feedback during prototyping.

Q17. RAD reduces development time by:.
  1. Delaying testing
  2. Avoiding prototyping
  3. Reusing components and parallel development
  4. Increasing paperwork

Answer: c, Reusing components and parallel development

Solution: Component reuse and parallel work shorten development time.

Q18. RAD is similar to which other model?.
  1. Spiral Model
  2. Iterative Model
  3. Waterfall Model
  4. V-Model

Answer: b, Iterative Model

Solution: RAD follows an iterative approach.

Q19. Which is true about RAD?.
  1. It requires a large team of skilled developers
  2. It does not involve users
  3. Development is sequential
  4. Prototyping is discouraged

Answer: a, It requires a large team of skilled developers

Solution: RAD needs strong technical teams for rapid delivery.

Q20. The major drawback of RAD is:.
  1. Poor user involvement
  2. High cost for skilled resources and tools
