In a CI/CD pipeline, the _______ stage is responsible for ensuring that the code changes do not break the existing functionality.
- Deployment
- Integration
- Testing
- Validation
In a CI/CD pipeline, the "Validation" stage ensures that code changes do not break existing functionality by running tests and checks before deployment.
The _____ approach in prototyping involves building small and incremental portions of a system and expanding upon it based on feedback.
- Agile
- Big Bang
- Incremental
- Spiral
The _____ approach in prototyping involves building small and incremental portions of a system and expanding upon it based on feedback. It is known as the "Incremental" approach and is common in Agile methodologies.
What is the main purpose of Configuration Management in software development?
- Accelerating software testing.
- Enhancing user interface design.
- Managing and controlling changes to software.
- Minimizing software development costs.
Configuration management is vital for controlling changes, versions, and ensuring consistency in software development, helping manage the software's lifecycle.
How can integrating a bug tracking system with a continuous integration pipeline enhance the software development process?
- It hinders code deployment.
- It improves collaboration and issue resolution.
- It increases the number of bugs.
- It slows down the development process.
Integrating a bug tracking system with a continuous integration pipeline enhances software development by improving collaboration, identifying and resolving issues early, and ensuring higher software quality.
How do denormalization techniques in database design impact system performance and data redundancy?
- Degrade system performance and increase redundancy
- Have no impact on system performance
- Improve redundancy but not system performance
- Improve system performance and reduce redundancy
Denormalization in database design involves reducing the level of normalization for performance reasons. While it can improve query performance, it may increase data redundancy and degrade system performance due to extra storage and maintenance overhead.
In software maintenance, _____ refers to the practice of regularly checking and updating software to ensure its optimal performance.
- Adaptive
- Corrective
- Perfective
- Preventive
Preventive maintenance involves regular checks and updates to ensure software's optimal performance, preventing issues before they occur.
How does the Implementation phase of the SDLC differ from the Design phase?
- Design focuses on user requirements, while Implementation focuses on system requirements.
- Design is about coding, and Implementation is about testing.
- Design is about fixing bugs, and Implementation is about finding them.
- Design phase focuses on planning, while Implementation is about coding.
The Design Phase primarily focuses on planning and conceptualizing the software, while the Implementation Phase involves coding or programming the actual software.
Which aspect of User Interface Design focuses on ensuring that the system provides feedback to the user after every interaction?
- Content and images.
- Layout and color choice.
- Navigation and menus.
- Responsiveness and feedback.
Responsiveness and feedback are crucial aspects of User Interface Design. These ensure that the system responds to user actions with clear feedback. It's essential for usability, as users need to know their interactions have been registered, preventing confusion and frustration. Responsiveness includes things like button highlighting or confirming actions, enhancing the user experience.
In a scenario where a project has a tight deadline and minimal initial requirements, how does Agile provide an advantage over traditional SDLC models?
- Agile embraces change and focuses on delivering working software incrementally
- Agile focuses on detailed documentation
- Agile follows a rigid schedule and fixed scope
- Agile prioritizes detailed project planning
Agile provides an advantage in such a scenario by delivering working software incrementally and adapting to changing requirements, making it suitable for tight deadlines and minimal initial requirements.
In Software Architecture Design, the _____ pattern helps in minimizing the communication and dependencies between different modules.
- Adapter
- Mediator
- Observer
- Singleton
The Mediator design pattern is used in Software Architecture Design to minimize the communication and dependencies between different modules by centralizing complex interactions and communication.
