By creating _____ in a database, you can speed up the retrieval of rows from a database table.
- Aggregates
- Indexes
- Procedures
- Views
By creating "Indexes" in a database, you can speed up the retrieval of rows from a database table. Indexes provide a faster way to locate specific data, enhancing database query performance.
To simulate network latency and test how an application performs under stress, _____ testing is conducted.
- Load
- Penetration
- Performance
- Stress
Load testing is a type of testing that simulates network latency and tests how an application performs under stress by subjecting it to various loads. It helps determine the application's response time, scalability, and reliability under different levels of user activity, ensuring it can handle the expected workload.
What are the key components of an effective incident response strategy?
- Assigning blame and reprimanding staff
- Communication and collaboration
- Delaying any action
- Ignoring the incident
An effective incident response strategy includes communication and collaboration, not assigning blame. It's important to respond promptly, work together, and learn from the incident to improve future responses. Ignoring or delaying an incident is not a recommended approach.
Test-Driven Development (TDD) emphasizes the principle of _____, where the codebase is continually adjusted to enhance its functionality and maintainability.
- Code Reliability
- Refactoring
- Test Automation
- Waterfall Development
Test-Driven Development (TDD) emphasizes the principle of refactoring, where the codebase is continually adjusted and improved to enhance its functionality and maintainability. This ensures the code remains clean and efficient.
In what way does the Agile methodology attempt to overcome the limitations of traditional SDLC models regarding customer feedback?
- It conducts feedback sessions only after project completion.
- It has no provisions for feedback.
- It involves customers throughout the development process.
- It minimizes customer involvement.
Agile methodology differs from traditional SDLC by involving customers at every stage, ensuring continuous feedback. This helps in addressing evolving customer needs and preferences, a limitation of traditional models.
In Test-Driven Development, the process of writing tests before writing the corresponding code is known as _____.
- Code Testing
- Code-First Testing
- Post-Development Testing
- Test-First Development
In Test-Driven Development (TDD), the process of writing tests before writing the code is known as "Test-First Development." It helps ensure code quality and adherence to requirements.
What is the primary goal of the requirement gathering process in software development?
- Conduct product testing
- Define the color scheme
- Identify potential team members
- Understand and document the needs of stakeholders
The primary goal of the requirement gathering process is to understand and document the needs and expectations of stakeholders, which helps in creating a software system that meets their requirements.
The _______ phase of the SDLC involves validating the requirements to ensure they align with the project's objectives.
- Design
- Planning
- Requirements
- Testing
The Requirements phase of the SDLC involves validating the requirements to ensure they align with the project's objectives. This phase is crucial for establishing a clear project scope and ensuring that the requirements are realistic and achievable.
The _____ phase of the SDLC involves rigorous testing to ensure that the software meets all specified requirements and is ready for production.
- Development
- Maintenance
- Planning
- Testing
The Testing phase of the SDLC is where rigorous testing is conducted to validate that the software meets specified requirements and is ready for production.
What challenges might a software development team face when using a throwaway prototyping model?
- It eliminates all bugs.
- It ensures low cost.
- It provides a systematic approach.
- It speeds up development.
The throwaway prototyping model involves creating a quick, disposable prototype to understand requirements. Challenges include the potential for wasted effort if the prototype isn't reused and a risk of misunderstanding that the prototype is the final product.
