The process of identifying bottlenecks, or slow-performing areas in a software application, is known as _____ testing.
- Black-box
- Performance
- Usability
- White-box
Performance testing is the process of identifying bottlenecks or slow-performing areas in a software application, ensuring it meets performance requirements.
You are part of a team developing a new social media application. In which phase of the SDLC would your team ensure that the application can handle a large number of simultaneous users without performance degradation?
- Design Phase
- Maintenance Phase
- Requirements Phase
- Testing Phase
The team would ensure performance in the Testing Phase. This phase includes load testing, stress testing, and performance testing to verify that the application can handle a large number of users without degrading performance.
The _____ phase of incident response involves taking actions to minimize the impact of an incident and prevent further damage.
- Detection
- Mitigation
- Prevention
- Recovery
The mitigation phase in incident response involves taking actions to minimize the impact of an incident and prevent further damage, often by isolating affected systems and applying security measures.
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.
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.
