_____ is a testing framework used in .NET applications to facilitate unit testing.
- JUnit
- NUnit
- PyTest
- Selenium
NUnit is a popular testing framework used in .NET applications to facilitate unit testing. It provides a way to write and run tests to verify the functionality of individual components or units within a software application. NUnit is widely used in the .NET ecosystem to ensure code quality.
What challenges might an organization face when implementing a Blue-Green deployment strategy at scale?
- Complex infrastructure management
- Increased resource utilization
- Reduced testing capabilities
- Slower time-to-market
Implementing Blue-Green deployment at scale can lead to challenges such as complex infrastructure management, maintaining separate environments, and ensuring data consistency between them. This can impact testing capabilities and require careful planning.
________ 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 _____ 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.
What is one of the key benefits of using a structured SDLC in software development?
- Faster development
- Improved quality
- Increased flexibility
- Reduced cost
One of the key benefits of using a structured SDLC is improved quality. A structured approach allows for systematic testing, documentation, and verification, resulting in high-quality software.
A team has documented the requirements for a new software application. However, upon review, several stakeholders provide conflicting feedback. How should the team proceed to resolve the discrepancies in the documented requirements?
- Host a requirements workshop with the stakeholders to reach a consensus
- Include all conflicting requirements in the final document
- Make a decision based on the highest authority's preference
- Prioritize the requirements based on the team's judgment
To resolve discrepancies in documented requirements, it's best to host a requirements workshop with stakeholders. This collaborative approach allows stakeholders to discuss, negotiate, and reach a consensus on conflicting requirements, ensuring alignment with the project's goals.
