Fundamentals of DevOps

What is Continuous Integration (CI)?

• A technique for manual code review

• Continuous Integration (CI) is a practice of automating the integration of code changes from multiple contributors into a single software project.

• A process for merging database changes only

• A method for deploying software updates automatically

Which tool is commonly used for CI?

• Travis CI

• GitHub Actions

• CircleCI

• Jenkins

What is the primary goal of Continuous Deployment (CD)?

• To create a backup of the software before any changes are made.

• To limit the frequency of software updates to once a month.

• To ensure all software changes are manually reviewed before release.

• To automate the release of software changes to production.

How does Continuous Deployment differ from Continuous Delivery?

• Continuous Deployment is only used for mobile applications.

• Continuous Deployment requires manual testing before release.

• Continuous Deployment automates the release to production, while Continuous Delivery requires manual deployment.

• Continuous Delivery automates the release to production.

What is a Version Control System (VCS)?

• A Version Control System (VCS) is a tool that manages changes to source code, allowing collaboration and tracking of modifications.

• A Version Control System is a method for designing user interfaces.

• A Version Control System is a database for storing images.

• A Version Control System is a type of hardware for computers.

Name a popular Version Control System.

• Perforce

• Git

• Mercurial

• Subversion

What is the purpose of branching in a VCS?

• To ensure all developers work on the same version of the project

• To simplify the code review process

• To increase the size of the repository

• The purpose of branching in a VCS is to enable parallel development and manage different versions of a project.

What does the term 'merge' refer to in version control?

• The process of deleting branches in version control.

• The act of creating a new branch from an existing one.

• The method of tracking changes in a single file.

• The process of combining changes from different branches in version control.

How does collaboration enhance the DevOps process?

• Collaboration isolates teams, leading to less accountability.

• Collaboration slows down the DevOps process by creating confusion.

• Collaboration enhances the DevOps process by improving communication, accelerating feedback, and fostering a culture of shared responsibility.

• Collaboration eliminates the need for automation in DevOps.

What role do automated tests play in CI/CD?

• Automated tests validate code changes, catch bugs early, and maintain quality in CI/CD.

• Automated tests are not necessary for maintaining code quality.

• Automated tests slow down the CI/CD process.

• Automated tests are only useful for frontend development.
