How does the choice of indexing strategy impact database performance, particularly in large-scale databases?
- It has no impact on database performance
- It slows down the database
- It improves database performance
- It only affects data storage
The choice of indexing strategy can significantly impact database performance, especially in large-scale databases. Indexing enhances data retrieval speed by providing quick access to specific records. An appropriate indexing strategy can lead to faster query execution and overall database optimization.
What would be a key indicator that a software system has passed a stress test?
- No security vulnerabilities
- Rapid response time under stress
- High memory usage
- No code bugs
Passing a stress test is often indicated by the software system maintaining a rapid response time and performing well under high-stress conditions. A slowdown in response time or performance degradation could indicate a failure.
The _____ model for software evolution emphasizes the importance of feedback and uses it for the next iteration of system development.
- Waterfall
- Agile
- V-Model
- Spiral
The Agile model for software evolution emphasizes the importance of feedback. Agile methodologies such as Scrum and Kanban rely on iterative development with frequent feedback loops. This feedback is crucial for making improvements and adapting the system throughout its development.
Why is it crucial to consider the Technical Debt metric in the long-term sustainability of a software project?
- Technical Debt assesses project budget
- Technical Debt measures code complexity
- Technical Debt tracks the frequency of code changes
- Technical Debt represents the cost of delayed refactoring and quality improvements
It is crucial to consider the Technical Debt metric in the long-term sustainability of a software project because it represents the cost of delayed refactoring and quality improvements. Accumulated technical debt can lead to increased maintenance costs and reduced system stability, making it essential for long-term sustainability.
A _______ review is an evaluation of a software product or process performed by peers of the producers of the product.
- Self
- Peer
- Formal
- Managerial
A "peer" review is an evaluation of a software product or process carried out by individuals who are peers or colleagues of the producers of the product. This review involves feedback and assessment from those who have a similar level of expertise in the subject matter. Peer reviews help identify defects, enhance quality, and promote collaboration among team members.
The efficiency of regression testing can be significantly enhanced by employing ______ testing strategies.
- Agile
- Automated
- Black-box
- Manual
The efficiency of regression testing can be significantly enhanced by employing automated testing strategies. Automated regression tests can be quickly and repeatedly executed, allowing for faster feedback and more extensive test coverage, especially in large and complex software systems.
How does Change Control assist in managing alterations in the software project without hampering its stability or quality?
- Change Control hinders any alterations to the project.
- Change Control permits changes without any oversight.
- Change Control enforces a structured process for evaluating and implementing changes.
- Change Control bypasses the need for testing and validation.
Change Control is a structured process that helps manage changes to a software project without compromising its stability or quality. It ensures that changes are properly evaluated, tested, and validated before implementation, reducing the risk of introducing defects.
Why is it crucial to align software testing objectives with business objectives?
- It's not crucial
- It ensures that the software works perfectly
- It helps prioritize testing efforts and meet business goals
- It increases the cost of testing
Aligning software testing objectives with business objectives ensures that testing efforts are directed towards the most critical aspects that impact business success. It helps identify and address issues that can affect business outcomes.
Quality Assurance in Agile involves regular _______ to discuss any issues or changes needed in the ongoing project.
- Documentation reviews
- Risk assessments
- Status meetings
- Testing phases
Quality Assurance in Agile involves regular status meetings to discuss any issues or changes needed in the ongoing project. These meetings help ensure that the project aligns with its goals and that quality is maintained.
A _____ architecture style has a single codebase and is often easier to deploy.
- Monolithic
- Microservices
- Client-Server
- Peer-to-Peer
The Monolithic architecture style has a single codebase, and it is often easier to deploy as the entire application is packaged as a single unit. This simplicity can make deployment and maintenance more straightforward.
