What considerations are typically evaluated during the Feasibility Study in the initial phases of the SDLC?
- Hardware requirements
- Market analysis
- Software testing
- Technical feasibility
During the Feasibility Study in the initial phases of SDLC, technical feasibility assesses whether the proposed project is technically possible, considering hardware, software, and other technical requirements. This evaluation helps decide whether to proceed with the project. Other aspects like market analysis, hardware, and software testing are considered later in the SDLC.
A company notices that their application slows down during peak usage times. Which monitoring and logging metrics would be most beneficial to diagnose the issue?
- Employee satisfaction
- Marketing campaign success
- Memory usage, CPU utilization
- Number of bug fixes
Monitoring and logging metrics like memory usage and CPU utilization are crucial to diagnose performance issues during peak usage. These metrics help identify resource bottlenecks causing slowdowns.
A company wants to deploy a critical update to its software without causing any downtime. Which deployment strategy would be most suitable?
- Blue-Green Deployment
- Canary Deployment
- Parallel Deployment
- Rolling Deployment
Blue-Green Deployment is suitable for deploying critical updates without downtime. It involves creating an identical environment and switching traffic once the update is validated, ensuring minimal disruption to users.
________ testing is a type of performance testing that evaluates how a system behaves under an increasing load, often beyond its specified requirements.
- Compatibility
- Regression
- Stress
- Usability
Stress testing is a form of performance testing that assesses how a system behaves under increasing loads or stress. It often involves pushing the system beyond its specified requirements to identify performance bottlenecks and issues under heavy usage.
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.
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.
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 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.
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.
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.
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.
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.
