Software Engineering

1. 1.Which of the following is a primary characteristic of the Waterfall model?

• a. It is an iterative and incremental approach.

• b. It is best suited for projects with unclear requirements.

• c. Each phase must be completed before the next phase begins.

• d. It emphasizes customer collaboration over process and tools.

Answer explanation

The Waterfall model follows a linear, sequential flow, where a phase's completion is a prerequisite for starting the next.

2. 2.Which software life cycle model focuses on managing project risk by allowing a project team to evaluate and address risk at each phase?

• a. Agile Model

• b. Waterfall Model

• c. Rapid Application Development (RAD)

• d. Spiral Model

Answer explanation

The Spiral model is an iterative life cycle model that places a heavy emphasis on risk analysis and mitigation in each cycle or 'spiral'.

3.The process of understanding what the user wants to achieve and identifying the constraints on the software is called:

• a. Software Design

• b. Requirements Analysis

• c. Coding

• d. Testing

4.What is the main purpose of a Software Requirements Specification (SRS) document?

• a. To serve as a user manual for the final software product.

• b. To provide a clear, unambiguous, and verifiable description of the software's requirements.

• c. To outline the project schedule and budget.

• d. To document the architecture and detailed design of the software.

2. 5.Which phase in the software development life cycle is primarily focused on verifying that the software meets the specified requirements?

• a. Design

• d. Maintenance

• b. Implementation

• c. Testing

6.Which document serves as a formal agreement between stakeholders and developers regarding the software requirements?

• a. Software Design Document

• d. Test Plan

• c. User Manual

• b. Software Requirements Specification (SRS)

7.Which of the following is NOT a characteristic of a good SRS document?

• a. It is vague.

• b. It is verifiable.

• c. It is consistent.

• It is modifiable

Answer explanation

A good SRS must be unambiguous and precise, not vague, to avoid misinterpretation and errors in development.

8.What is a Formal System Specification?

• a. A document written in a natural language like English.

• b. A specification that outlines the project's budget and timeline.

• c. A specification written using mathematical notations and logic to precisely and unambiguously define the system's behavior.

• d. A document created by the user to describe their requirements informally.

9.Which of the following is a key value of the Agile Manifesto?

• a. Comprehensive documentation over working software.

• b. Following a plan over responding to change.

• c. Processes and tools over individuals and interactions.

• d. Customer collaboration over contract negotiation.

10.Which of the following correctly lists the phases of the Waterfall model in their proper sequential order?

• a. Design, Requirements Analysis, Testing, Implementation (Coding), Deployment & Maintenance

• b. Implementation (Coding), Design, Requirements Analysis, Testing, Deployment & Maintenance

• c. Requirements Analysis, Testing, Design, Implementation (Coding), Deployment & Maintenance

• d. Requirements Analysis, Design, Implementation (Coding), Testing, Deployment & Maintenance
