Which of the following is a common tool used in configuration management?

GitHub is widely recognized as a common tool used in configuration management because it provides version control capabilities that allow developers to track changes in their codebase over time. With GitHub, teams can manage the development of software projects collaboratively, ensuring that changes are documented, reversible, and can be integrated seamlessly from multiple contributors. The platform leverages Git, a powerful version control system, which is essential for maintaining the integrity and history of source code across various stages of development.

Configuration management specifically involves managing changes to system components and their configurations. Tools like GitHub enable efficient handling of code changes, allow for branching and merging, and facilitate collaboration among team members, which are key aspects of effective configuration management.

In contrast, while Visual Studio is an integrated development environment that allows programmers to write and debug code, it does not specifically focus on configuration management. MySQL is a relational database management system and does not relate directly to configuration management practices. Jira is a project management tool, often used for issue tracking and agile project management, but it is not primarily focused on version control and code management.
