What is the first phase in the Software Development Life Cycle (SDLC)?
A Coding
B Planning
C Design
D Testing
The first phase of the SDLC is planning, where the project scope, objectives, and requirements are defined. This phase ensures the development team understands the project’s goals, leading to efficient resource allocation and execution.
Which of the following is a feature of Agile methodology?
A Flexibility
B Fixed timeline
C Rigid process
D Waterfall structure
Agile methodology emphasizes flexibility and iterative development. It allows for rapid changes, continuous improvement, and regular feedback from stakeholders, enabling software to adapt to evolving needs during the project.
What does the Waterfall model emphasize in software development?
A Rapid changes
B Continuous integration
C Iterative cycles
D Sequential phases
The Waterfall model follows a linear and sequential approach, where each phase (requirements, design, coding, testing, deployment) is completed before moving on to the next. This model is suitable for projects with well defined requirements.
What is the primary advantage of using UML diagrams in software design?
A Visual representation
B Performance analysis
C Faster coding
D Code generation
UML diagrams provide a standardized way to visualize system architecture, behavior, and design. They help stakeholders, including developers and non technical teams, understand the structure and flow of a software system clearly and intuitively.
What does Object Oriented Design (OOD) focus on?
A User interface
B Data encapsulation
C Code execution
D Program performance
Object Oriented Design focuses on organizing software into objects that encapsulate data and behavior. It promotes principles like inheritance, polymorphism, and encapsulation to make software more modular, reusable, and maintainable.
What type of requirement describes the system’s behavior?
A Security
B Technical
C Functional
D Non functional
Functional requirements describe the specific behaviors, functions, or actions that the software must perform. They define what the system will do, such as processing transactions, handling user inputs, or managing data.
Which of the following is a non functional requirement?
A System performance
B User authentication
C Data processing
D Reporting
Non functional requirements specify how the system should perform, focusing on aspects like performance, reliability, scalability, and security. They describe how well the system operates under various conditions, such as load or stress.
What does API design typically focus on?
A User interface
B Data storage
C System security
D System interaction
API design focuses on defining the methods and protocols for interaction between software systems. It specifies how different software components communicate with each other, ensuring seamless integration and data exchange between systems.
What is the primary purpose of version control systems like Git?
A Code collaboration
B User authentication
C Software deployment
D Code documentation
Version control systems like Git enable multiple developers to collaborate on the same codebase. They track changes, manage different versions of the code, and help prevent conflicts when merging contributions from different developers.
Which of the following is a key practice in DevOps?
A Manual deployment
B Continuous testing
C Code debugging
D Code refactoring
DevOps emphasizes continuous testing to ensure that code changes are thoroughly tested at every stage of development. This practice improves software quality by identifying and addressing issues early in the development process.
What is a key benefit of using microservices architecture?
A Single database
B Simplified deployment
C Easier scalability
D Faster development
Microservices architecture allows each service to be scaled independently, providing better flexibility and scalability. It enables developers to scale parts of the system based on demand, improving overall system performance and resource efficiency.
What is the purpose of continuous integration (CI)?
A Write tests
B Optimize performance
C Automate deployments
D Merge code changes
Continuous integration involves frequently merging code changes into a shared repository. Automated builds and tests are run to detect integration issues early, ensuring that the software remains functional and reliable throughout development.
What is the main purpose of regression testing?
A Test code coverage
B Ensure existing features work
C Test user interfaces
D Identify new bugs
Regression testing ensures that new changes or updates do not negatively impact existing functionality. It verifies that previously working functionality continues to perform correctly, preventing unintended side effects from code changes.
What is the main advantage of the Agile model?
A Flexibility and adaptability
B Sequential process
C Detailed upfront planning
D Predictable timeline
The Agile model is highly flexible and adaptable. It allows for iterative development and frequent feedback from stakeholders, enabling the software to evolve and adjust based on changing requirements throughout the development cycle.
What does the “testing” phase in SDLC focus on?
A Designing system architecture
B Coding and debugging
C Verifying software quality
D Analyzing requirements
The testing phase in the SDLC focuses on verifying that the software meets the specified requirements and is free of bugs. It includes various types of testing, such as unit, integration, and acceptance testing, to ensure software quality.
