B) Inability to handle evolving requirements efficiently C) Iterative development D) High customer involvement Answer: B Explanation: Waterfall is rigid; it does not accommodate changes easily once a phase is completed, making it unsuitable for evolving requirements. Question 9. Which process model is most suitable for projects with unclear or evolving requirements? A) Waterfall B) Incremental C) Spiral D) V-Model Answer: C Explanation: The Spiral Model emphasizes iterative risk analysis and prototyping, making it suitable for projects with uncertain requirements. Question 10. Which core value is emphasized in the Agile Manifesto? A) Strict planning over responding to change
Exam A
C) Deploy the final product D) Complete documentation Answer: B Explanation: Sprint planning involves selecting and prioritizing backlog items to be completed in the next sprint, enabling iterative progress. Question 13. Which is a principle of Lean Software Development? A) Maximize waste B) Deliver value quickly and eliminate waste C) Emphasize heavy documentation D) Rely solely on individual heroics Answer: B Explanation: Lean principles focus on eliminating waste, delivering value fast, and optimizing the entire process flow. Question 14. What is the primary focus of DevOps? A) Separating development and operations B) Automating deployment and fostering collaboration between development and operations
Exam A
C) Reducing software quality D) Increasing manual testing Answer: B Explanation: DevOps aims to unify development and operations through automation, continuous integration, and collaboration to improve delivery speed. Question 15. Which process framework is known for its iterative, risk-driven approach and use in large-scale systems engineering? A) Rational Unified Process (RUP) B) Waterfall Model C) Incremental Model D) V-Model Answer: A Explanation: RUP emphasizes iterative development, risk management, and comprehensive documentation, suitable for complex projects. Question 16. Which maturity model assesses the capability of an organization’s software processes?
Exam A
Question 18. Which technique is used during requirements elicitation to gather user needs? A) Code review B) Interviews C) System testing D) Deployment Answer: B Explanation: Interviews are a common elicitation technique to gather detailed user requirements directly from stakeholders. Question 19. Which model depicts system behavior through states and transitions? A) Data flow diagram B) State diagram C) Entity-relationship diagram D) Class diagram Answer: B Explanation: State diagrams model the system's states and transitions based on events, illustrating dynamic behavior.
Exam A
Question 20. Which UML diagram is primarily used to represent the static structure of a system? A) Sequence diagram B) Class diagram C) Activity diagram D) State diagram Answer: B Explanation: Class diagrams illustrate the static structure, including classes, attributes, and relationships. Question 21. Which design principle promotes dividing a system into independent modules? A) Coupling B) Modularity C) Cohesion D) Abstraction Answer: B Explanation: Modularity involves partitioning a system into modules that encapsulate functionality, enhancing maintainability.
Exam A
Question 24. In object-oriented design, which concept allows a subclass to inherit behavior from a superclass? A) Encapsulation B) Inheritance C) Polymorphism D) Abstraction Answer: B Explanation: Inheritance enables a class (subclass) to acquire properties and behaviors of another class (superclass). Question 25. Which UX design principle focuses on designing interfaces that are easy for users to understand and use? A) Internationalization B) User-centered design C) Performance optimization D) Security Answer: B Explanation: User-centered design emphasizes designing interfaces based on user needs, tasks, and preferences.
Exam A
Question 26. Which notation is most commonly used to represent software components and their interactions? A) Entity-relationship diagram B) UML component diagram C) Data flow diagram D) State diagram Answer: B Explanation: UML component diagrams depict software components and their relationships, useful for component-based design. Question 27. Which programming paradigm emphasizes data encapsulation, inheritance, and polymorphism? A) Structured programming B) Object-oriented programming C) Functional programming D) Procedural programming Answer: B Explanation: Object-oriented programming centers around classes and objects, utilizing inheritance, encapsulation, and polymorphism.
Exam A
Question 30. Which automated tool is used to create, manage, and run containerized applications? A) Jenkins B) Docker C) Git D) Selenium Answer: B Explanation: Docker provides containerization, allowing applications and their dependencies to run consistently across environments. Question 31. Which testing level verifies individual units of source code? A) System testing B) Integration testing C) Unit testing D) Acceptance testing Answer: C Explanation: Unit testing focuses on testing individual units or components of the software in isolation.
Exam A
Question 32. Which testing principle states that testing should show the presence of defects, not their absence? A) Exhaustive testing B) Pesticide paradox C) Testing shows failures D) Defect clustering Answer: C Explanation: Testing aims to uncover failures, but absence of failures does not guarantee the absence of defects. Question 33. Which type of testing is primarily concerned with evaluating the system's responsiveness under load? A) Usability testing B) Performance testing C) Security testing D) Functional testing Answer: B Explanation: Performance testing assesses system responsiveness, scalability, and stability under various load conditions.
Exam A
Question 36. What is the role of defect prevention in software quality management? A) Detecting defects after deployment B) Eliminating causes of defects early in development C) Ignoring defects during coding D) Fixing defects only during testing Answer: B Explanation: Defect prevention aims to identify and eliminate root causes of defects early, reducing overall defect rates.
