The _____ maintenance model involves making changes to a software product to correct issues discovered after its initial release.
- Adaptive
- Corrective
- Perfective
- Preventive
Corrective maintenance is the process of making changes to a software product to correct issues and defects discovered after its initial release. This type of maintenance aims to fix problems without adding new features or altering existing functionality.
What is the primary purpose of a bug tracking system in software development?
- Document software design
- Enhance software performance
- Facilitate communication among team members
- Track and manage software defects
A bug tracking system's primary purpose is to track and manage software defects, also known as bugs or issues. It helps in identifying, prioritizing, and resolving issues to improve software quality.
Why is the Software Development Life Cycle (SDLC) considered important for the development of high-quality software?
- It eliminates all bugs.
- It ensures low cost.
- It provides a systematic approach.
- It speeds up development.
SDLC is important because it offers a structured and systematic approach to software development. It helps in managing requirements, quality, and risk, leading to high-quality software.
How does the Agile model in SDLC enhance customer satisfaction compared to traditional models?
- Agile model encourages extensive documentation.
- Agile model follows a rigid, sequential process.
- Agile model minimizes customer involvement.
- Agile model provides frequent, customer-driven feedback.
The Agile model promotes customer satisfaction by involving them throughout the development process. It emphasizes iterative development and regular feedback, ensuring the final product aligns with customer needs and desires.
A team is designing a complex software system with multiple interacting components. Which SOLID principle would be most crucial to ensure that changes in one component do not require changes in others?
- Dependency Inversion Principle (DIP)
- Liskov Substitution Principle (LSP)
- Open/Closed Principle (OCP)
- Single Responsibility Principle (SRP)
The Single Responsibility Principle (SRP) is crucial in complex systems to ensure that changes in one component don't affect others. It promotes modular design, reducing the ripple effect of changes.
Using _____ tools during code review can help automate the process of checking for syntax errors and coding standard violations.
- Debug
- Debugging
- Linting
- Profiling
Using linting tools during code review can automate the process of checking for syntax errors and adherence to coding standards, enhancing code quality.
In Test-Driven Development (TDD), what is the purpose of writing a failing test before implementing the code?
- To confuse developers.
- To ensure code meets requirements.
- To increase development time.
- To make testing unnecessary.
In TDD, writing a failing test first ensures that the code you write is designed to meet specific requirements. It acts as a guide for code implementation, driving development towards the desired outcome.
In the context of SOLID principles, how does the Dependency Inversion Principle aid in creating a flexible architecture?
- It allows high-level modules to depend on abstractions and not concrete implementations.
- It encourages high dependence on concrete implementations.
- It enforces that high-level modules should always use concrete implementations directly.
- It promotes tight coupling between modules.
The Dependency Inversion Principle (DIP) in SOLID principles advocates that high-level modules should depend on abstractions (interfaces or abstract classes) rather than concrete implementations. This promotes flexibility and allows different implementations to be swapped without affecting the high-level module. DIP aids in creating a flexible and maintainable architecture.
_____ testing is more suitable for tasks that require repeated execution, while _____ testing is often more suitable for exploratory or usability testing.
- Exploratory, Regression
- Integration, Unit
- Regression, Exploratory
- Unit, Integration
"Unit testing" is more suitable for tasks that require repeated execution, focusing on individual components. "Integration testing" is suitable for verifying interactions between components.
How do Source Code Management tools aid in collaborative development?
- By automating testing
- By preventing errors
- By tracking changes and versions
- By writing code quickly
Source Code Management tools, like Git, aid collaborative development by tracking changes, maintaining version history, and enabling team members to work on the same codebase concurrently, ensuring collaboration and version control.
The _____ principle in coding best practices advocates that a function or module should only have responsibility over a single part of the functionality.
- Agile
- DRY
- RAD
- SOLID
The blank should be filled with "SOLID." The SOLID principles are a set of five principles that help in designing maintainable and scalable software. The Single Responsibility Principle (SRP) is one of these principles and emphasizes that a function or module should have a single responsibility.
The _____ deployment strategy allows for easy rollback and minimal downtime by having two separate environments.
- Agile
- Blue-green
- Scrum
- Waterfall
The Blue-Green deployment strategy allows for easy rollback and minimal downtime by having two separate environments. It ensures seamless updates and testing in a controlled manner.
