Mastering Software Development

What is the primary purpose of version control systems?

• To store files in a cloud storage service.

• To create backups of all project files automatically.

• To manage changes to source code and facilitate collaboration among multiple contributors.

• To track the performance of software applications.

Explain the difference between Agile and Waterfall methodologies.

• Waterfall allows for changes at any stage, while Agile does not.

• Agile is iterative and flexible, while Waterfall is linear and sequential.

• Agile focuses on documentation, while Waterfall prioritizes customer collaboration.

• Agile is a one-time process, while Waterfall is ongoing.

What does the acronym API stand for in software development?

• Application Programming Interface

• Application Programming Indicator

• Advanced Programming Interface

• Application Performance Index

What is the role of a software architect?

• To manage the marketing strategy of software products.

• To conduct user training sessions for software systems.

• To write and debug code for software applications.

• The role of a software architect is to design and oversee the architecture of software systems.

Define the term 'refactoring' in the context of software development.

• Refactoring is the process of adding new features to existing code.

• Refactoring involves rewriting code from scratch to improve performance.

• Refactoring is the act of debugging code to fix errors.

• Refactoring is the process of restructuring existing code to improve its quality without altering its functionality.

What is the significance of unit testing in software development?

• Unit testing is primarily used for user interface testing.

• Unit testing guarantees that the software is bug-free.

• Unit testing helps identify bugs early, ensures component functionality, facilitates refactoring, and improves code quality.

• Unit testing is only necessary for large projects.

Describe the concept of Continuous Integration (CI).

• Continuous Integration (CI) is a method of deploying code to production without testing.

• Continuous Integration (CI) is a practice of manually reviewing code changes before integration.

• Continuous Integration (CI) involves integrating code changes only at the end of a project.

• Continuous Integration (CI) is a practice of frequently integrating code changes into a shared repository with automated testing.

What programming paradigm does Object-Oriented Programming (OOP) belong to?

• Object-Oriented Programming (OOP) belongs to the Object-Based programming paradigm.

• Declarative Programming

• Procedural Programming

• Functional Programming

What is the purpose of a software development lifecycle (SDLC)?

• The purpose of SDLC is to provide a structured framework for planning, creating, testing, and deploying software.

• To define the hardware requirements for software installation.

• To outline the marketing strategy for software products.

• To establish a budget for software development projects.

Explain the concept of 'technical debt' in software projects.

• Technical debt refers to the amount of code written in a project.

• Technical debt is a measure of the total lines of code in a software application.

• Technical debt is the cost of hiring additional developers for a project.

• Technical debt is the trade-off between short-term benefits and long-term value in software development, often resulting from quick fixes and suboptimal solutions.
