The _____ phase of the SDLC ensures that the software continues to meet user needs and any errors or bugs are addressed.
- Deployment
- Maintenance
- Requirements
- Testing
The Maintenance phase in the SDLC is focused on maintaining and enhancing the software to ensure it continues to meet user needs and address any errors or bugs that may arise.
Which principle of User Interface Design suggests that the interface should keep consistency in its elements and layout?
- Consistency Principle
- Feedback Principle
- Flexibility Principle
- Visibility Principle
The Consistency Principle in User Interface Design suggests that the interface should maintain consistency in its elements and layout to create a more intuitive and user-friendly experience.
In the context of TDD, what are the implications of not refactoring code regularly?
- Better collaboration among developers.
- Code becomes rigid and less maintainable.
- Faster development.
- Improved code maintainability.
In TDD, not regularly refactoring code can lead to code rigidity and reduced maintainability. Refactoring is essential in TDD to keep the codebase clean, flexible, and adaptable to changing requirements. Failing to do so can result in difficulties during software evolution.
Which type of performance testing is aimed at understanding the scalability of an application?
- Capacity testing
- Endurance testing
- Load testing
- Stress testing
Load testing is focused on understanding an application's scalability by simulating expected user loads and evaluating its performance under these conditions. It helps determine how the system scales as the user load increases.
To ensure that documented requirements are not ambiguous or contradictory, it is essential to employ proper __________ techniques.
- Documentation
- Requirement Analysis
- Testing
- Validation
Proper requirement analysis techniques are essential to identify and clarify ambiguities and contradictions within documented requirements, improving the quality of the specifications.
How does a use case differ from a user story in terms of detail and scope?
- Use cases are more detailed and comprehensive than user stories.
- Use cases are primarily used in Waterfall projects, while user stories are for Agile projects.
- Use cases focus on technical details, while user stories focus on business needs.
- User stories are more detailed and comprehensive than use cases.
Use cases are typically more detailed and comprehensive than user stories. Use cases describe interactions and system behavior in detail, while user stories are high-level, brief descriptions of user needs.
What is the purpose of using a linter in the context of coding standards?
- To add comments to code
- To format the code for better readability
- To identify and fix bugs and errors
- To write shorter code
A linter in coding standards serves the purpose of identifying and fixing coding issues, bugs, and errors. It enforces coding style and consistency, leading to better code quality and maintainability.
In Functional Programming, side effects are avoided by emphasizing _______ and pure functions.
- Encapsulation
- Immutability
- Inheritance
- Mutability
In Functional Programming, side effects are avoided by emphasizing immutability and pure functions. Immutability ensures that data doesn't change after creation, and pure functions produce the same output for the same input, without side effects.
Which stage of the SDLC typically involves the validation of requirements to ensure they are clear and achievable?
- Design Phase
- Planning Phase
- Requirements Phase
- Testing Phase
The Requirements Phase in the SDLC typically involves the validation of requirements to ensure they are clear, complete, and achievable. This phase sets the foundation for the entire project.
In code review, what is the purpose of using automated tools to check code against certain standards and rules?
- To eliminate the need for manual review.
- To find and report issues efficiently.
- To increase code complexity.
- To slow down the review process.
Automated tools in code review are used to efficiently check code against standards and rules. They help identify issues such as coding style violations, potential bugs, and security vulnerabilities, streamlining the review process and ensuring code quality.
When comparing Agile and traditional SDLC models, how does the approach to risk management differ?
- Agile embraces risk and adapts to it.
- Agile focuses on risk avoidance.
- Traditional SDLC models have no risk management.
- Traditional SDLC models have strict risk planning.
In Agile, risk management differs as it embraces risk and adapts to changing circumstances, while traditional SDLC models often employ strict risk planning. Agile manages risk through continuous adaptation, fostering innovation and rapid response.
In database design, how does indexing improve query performance?
- It has no impact on query performance.
- It improves query performance.
- It only improves data storage.
- It slows down query performance.
Indexing in database design helps in faster data retrieval by creating a data structure that maps key values to their locations in the database. This significantly speeds up query performance, especially for large datasets.
