1Which of the following software development life cycle (SDLC) models is most appropriate for a project with well-defined, stable requirements that are unlikely to change during development?

A.Waterfall Model

B.Spiral Model

C.Incremental Model

D.Evolutionary Prototyping

Explanation: The Waterfall model is a linear, sequential SDLC model where progress flows steadily downwards through phases such as requirements analysis, design, implementation, testing, and maintenance. It is highly suitable for projects with stable, well-understood requirements because it assumes that each phase can be completed and signed off before the next begins, reducing the risk of costly redesigns.

2In the Scrum framework, which role is primarily responsible for maximizing the value of the product resulting from the work of the Scrum Team?

A.Scrum Master

B.Product Owner

C.Developers

D.Project Manager

Explanation: According to the official Scrum Guide, the Product Owner is solely responsible for maximizing the value of the product and the work of the Scrum Team. This is achieved by effectively managing the Product Backlog, defining backlog items clearly, ordering them to optimize value, and ensuring that the backlog is transparent and visible to all.

3What is the primary objective of a Sprint Retrospective in Scrum?

A.To inspect progress toward the Sprint Goal and adapt the Sprint Backlog.

B.To present the completed work increment to stakeholders and gather feedback.

C.To plan the work to be performed in the upcoming Sprint.

D.To inspect how the last Sprint went with regards to individuals, relationships, process, and tools, and identify improvements.

Explanation: The Sprint Retrospective is the final event of the Sprint. Its primary purpose is for the Scrum Team to inspect itself and plan improvements for the next Sprint. The team discusses what went well, what problems were encountered, how those problems were solved (or not), and commits to actionable process improvements.

4Which requirements engineering activity focuses on discovering what the stakeholders need from a software system?

A.Requirements Elicitation

B.Requirements Specification

C.Requirements Validation

D.Requirements Management

Explanation: Requirements Elicitation is the process of gathering, discovering, and understanding requirements from stakeholders, users, and other sources. It involves techniques such as interviews, workshops, surveys, observation, and document analysis to find out what capabilities the system must possess.

5A Software Requirements Specification (SRS) should be 'unambiguous'. What does this mean in the context of requirements quality?

A.Every requirement must have exactly one interpretation.

B.Every requirement must be measurable and testable.

C.All requirements must be organized in a logical structure.

D.The SRS must cover all necessary features and constraints.

Explanation: An unambiguous requirement is written in a way that allows only one clear interpretation by any reader (developers, testers, clients, etc.). Using precise, non-subjective language is essential to prevent developers from building a feature that behaves differently from what the user expected.

6Which of the following is a non-functional requirement (NFR)?

A.The system shall allow users to register with a valid email address.

B.The system shall generate a monthly sales report PDF.

C.The system shall process payment transactions within 2 seconds.

D.The system shall send an email notification when an order is placed.

Explanation: Non-functional requirements (NFRs) describe the quality attributes, constraints, or performance characteristics of a system, rather than specific behaviors. Processing transactions within 2 seconds is a performance constraint, which is a classic non-functional requirement.

7What is the primary benefit of using prototyping during requirements engineering?

A.It serves as the final production code for the project.

B.It helps resolve misunderstandings between users and developers by providing a tangible model.

C.It eliminates the need for any formal software testing.

D.It speeds up the final database schema design process.

Explanation: Prototyping involves building a simplified, experimental version of a system or component. Its primary benefit is to clarify user requirements, validate design assumptions, and resolve misunderstandings early in the lifecycle by giving stakeholders a concrete, interactive model to review.

8In Unified Modeling Language (UML) use case diagrams, what does an 'include' relationship between Use Case A and Use Case B mean?

A.Use Case A optionally triggers Use Case B based on runtime conditions.

B.Use Case B is a specialized version of Use Case A.

C.Use Case A always contains the behavior defined in Use Case B as part of its normal execution.

D.Use Case B and Use Case A execute concurrently in different threads.

Explanation: An 'include' relationship (modeled as <<include>>) indicates that the base use case (Use Case A) incorporates the behavior of the included use case (Use Case B) at a specific point. The execution of B is mandatory for the successful completion of A. It is often used to extract common, reusable behaviors across multiple use cases.

9Which Agile method is characterized by short, fixed-length sprints, daily standups, and roles including a Product Owner and a Scrum Master?

A.Extreme Programming (XP)

B.Scrum

C.Kanban

D.Feature-Driven Development (FDD)

Explanation: Scrum is an Agile framework characterized by iterative development structured into fixed-length Sprints (typically 1-4 weeks), 15-minute Daily Scrums, and three core roles: Product Owner, Scrum Master, and Developers. It focuses on delivering functional increments of value at the end of each iteration.

10Under the Agile Manifesto, what is valued more than 'following a plan'?

A.Responding to change

B.Working software

C.Customer collaboration

D.Processes and tools

Explanation: The Agile Manifesto states: 'Responding to change over following a plan.' It recognizes that while plans are useful, the ability to adapt to changes in requirements, technology, and market conditions is more critical to project success.
