Which scenario is more suitable for manual testing over automated testing?
- Ensuring complete code coverage.
- Load testing to simulate heavy user loads.
- Regression testing on a frequently changing codebase.
- Testing repetitive, time-consuming tasks.
Manual testing is more suitable for scenarios like load testing, which require a human perspective and judgment to simulate real-world usage conditions, something automation may struggle with.
Which coding best practice emphasizes making code understandable for both the computer and human readers?
- Code encryption
- Code obfuscation
- Code optimization
- Code readability
Code readability is a coding best practice that emphasizes making code understandable for both the computer and human readers. Clear and readable code is easier to maintain and debug.
Which of the following best describes the term "software update"?
- Adding new hardware
- Modifying software code
- Updating software to a newer version
- Upgrading the operating system
A "software update" refers to the process of updating software to a newer version. These updates typically include bug fixes, new features, and security improvements, ensuring the software's optimal performance.
The practice of _____ ensures that the codebase is continuously tested, helping to identify issues early in the development process.
- Code Review
- Continuous Integration
- Manual Testing
- User Acceptance Testing
Continuous Integration (CI) ensures that the codebase is continuously tested, often automatically, helping to identify issues early in the development process, promoting quality and collaboration.
A project manager is overseeing a large and complex software development project. What benefits would implementing a structured SDLC bring to this project?
- Better risk management
- Faster development
- Increased flexibility
- Reduced documentation
Implementing a structured SDLC, like Waterfall, offers better risk management. It allows for comprehensive planning and risk assessment, crucial for large and complex projects.
In database design, why is it important to establish relationships between different tables?
- It enforces referential integrity.
- It reduces database size.
- It simplifies data entry.
- It speeds up query performance.
Establishing relationships between tables in database design is important to enforce referential integrity, ensuring that data consistency is maintained and that relationships between data entities are maintained.
How does the Spiral model of SDLC aim to improve risk management in software development projects?
- By avoiding the planning phase altogether and proceeding directly to development
- By breaking the project into smaller, manageable iterations and emphasizing risk analysis
- By ignoring risks and focusing on rapid development
- By minimizing risk through extensive documentation and planning
The Spiral model enhances risk management by breaking the project into smaller iterations, allowing for continuous risk analysis and mitigation. It emphasizes risk identification and reduction throughout the development process.
The _______ SDLC model is well-suited for projects where requirements are expected to change frequently.
- Agile
- Spiral
- V-Model
- Waterfall
The Agile SDLC model is particularly suitable for projects with evolving requirements. It allows for flexibility and iterative development, accommodating changes during the development process.
How can principles of User Interface Design be leveraged to enhance the user experience in a data-intensive application?
- Focus on aesthetics and visual appeal
- Ignore user feedback
- Prioritize technical functionality
- Streamline data presentation and enhance data visualization
In a data-intensive application, prioritizing data presentation and leveraging data visualization techniques is crucial to enhancing the user experience. This approach helps users better understand complex data, make informed decisions, and interact with the application more effectively.
What is a common limitation of traditional SDLC models?
- Excessive cost
- Inflexibility
- Lack of documentation
- Slow development
A common limitation of traditional SDLC models is inflexibility, which makes it challenging to adapt to changing requirements or technology. This rigidity can lead to delays and higher costs.
