________ 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.
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.
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.
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.
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.
What role does a patch management system play in ensuring software security?
- It applies security updates and fixes
- It detects all security flaws
- It encrypts all data
- It prevents all security breaches
A patch management system is crucial for software security as it identifies and applies security updates and fixes, thereby addressing vulnerabilities that could be exploited by attackers.
How does automated testing improve the efficiency of the software development process compared to manual testing?
- Automated testing is faster and repeatable.
- Automated testing is less reliable.
- Automated testing requires manual documentation.
- Automated testing requires more human effort.
Automated testing is more efficient as it can quickly and consistently run tests, identify issues, and provide rapid feedback to developers, saving time compared to manual testing.
An organization regularly releases updates to improve the functionality and security of its software. How should these updates be managed to ensure minimal disruption to users?
- Ensure automated backup is in place.
- Implement scheduled maintenance windows.
- Notify users after the update.
- Release updates with no notification.
To ensure minimal disruption to users when releasing updates, it's best to implement scheduled maintenance windows to perform updates during times when user activity is low.
The process of checking if the requirements meet the needs and expectations of the stakeholders is known as ______.
- Documentation
- Implementation
- Validation
- Verification
Validation is the process of checking if the requirements meet the needs and expectations of the stakeholders. It ensures that the product being developed aligns with what the stakeholders actually require, thus increasing the chances of producing a successful product.
