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.
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.
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.
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.
During the _____ phase of the SDLC, stakeholders and developers decide whether the project is technically and financially feasible.
- Maintenance
- Planning
- Requirements
- Testing
The Planning phase in the SDLC is where stakeholders and developers decide whether the project is technically and financially feasible before committing to development.
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.
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.
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.
How do Agile methodologies address the limitation of traditional SDLC models in terms of responsiveness to changing requirements?
- By allowing changes only during planning.
- By avoiding change at all costs.
- By defining rigid change control processes.
- By welcoming and accommodating changes throughout the project.
Agile methodologies address the limitation of traditional SDLC models in responsiveness to changing requirements by welcoming and accommodating changes throughout the project. Agile's flexibility and iterative nature allow teams to respond to evolving customer needs and market conditions.
A software company wants to automate the process of code deployment so that any code commit triggers automated tests and deploys the code to production if the tests pass. Which practice would best serve this purpose?
- Continuous Delivery (CD)
- Continuous Deployment (CD)
- Continuous Integration (CI)
- Infrastructure as Code (IaC)
Continuous Deployment (CD) is a practice where code is automatically deployed to production after passing automated tests. It ensures rapid and reliable delivery of code changes.
