1. What is the main purpose of a version control system?
A. To increase the speed of software development
B. To keep track of code changes and manage code versions
C. To improve the user interface of the application
D. To test the software for bugs
Answer: B) To keep track of code changes and manage code versions
Rationale: Version control systems like Git help developers track changes to the
codebase and collaborate on development efficiently.
2. What is the primary purpose of refactoring code?
A. To add new features
B. To make the code more efficient
C. To improve the structure of the code without changing its behavior
D. To remove errors from the code
Answer: C) To improve the structure of the code without changing its behavior
Rationale: Refactoring involves improving the internal structure of the code to make it
cleaner, more readable, and maintainable, without altering its functionality.
,3. What does "debugging" refer to in software development?
A. Writing the first draft of the code
B. Removing unnecessary comments from the code
C. Fixing errors or bugs in the code
D. Testing the code for performance
Answer: C) Fixing errors or bugs in the code
Rationale: Debugging involves identifying and fixing issues or bugs in the software to
ensure it runs correctly.
4. What does "CI/CD" stand for in the context of DevOps?
A. Continuous Integration and Continuous Delivery
B. Continuous Improvement and Continuous Development
C. Code Integration and Code Deployment
D. Component Integration and Code Deployment
Answer: A) Continuous Integration and Continuous Delivery
Rationale: CI/CD refers to practices in DevOps where code changes are continuously
integrated and automatically delivered to production, ensuring a smoother release
process.
, 5. Which of the following programming languages is considered a compiled
language?
A. Python
B. Java
C. JavaScript
D. Ruby
Answer: B) Java
Rationale: Java is a compiled language, meaning that it is first compiled into

6. Which of the following is NOT a programming paradigm?
A. Object-Oriented Programming
B. Functional Programming
C. Procedural Programming
D. File Handling
Answer: D) File Handling
Rationale: File handling is not a programming paradigm; it refers to how files are
