Git & Version Control MCQ Practice Test

A system for tracking code changes and managing collaborative development history to ensure project stability and easy rollback.

Q1. In a cloud-based DevOps environment, which Git command is used to temporarily save changes that are not yet committed so they can be reapplied later?

Explanation: The 'git stash' command allows developers to save uncommitted changes temporarily, which is particularly useful in cloud environments when switching branches or pulling updates without losing work in progress.

Q2. Which Git feature enables automatic execution of deployment scripts when code is pushed to a specific branch in a cloud repository, aligning with DevOps CI/CD pipelines?

Explanation: Git Hooks are scripts that run automatically on specific events (like 'push' or 'commit'), making them ideal for triggering deployment workflows in cloud environments without manual intervention.

Q3. In a DevOps pipeline, which Git command is used to push local commits to a remote repository hosted on a cloud platform like AWS CodeCommit?

Explanation: The 'git push' command is used to send local commits to a remote repository, which is essential in DevOps for deploying code to cloud environments.

Q4. Which Git command is used to create an annotated tag for a specific commit in a cloud repository like GitLab?

Explanation: The 'git tag -a' command creates an annotated tag for a specific commit, which is useful in cloud repositories for marking release versions.

Q5. In a DevOps project hosted on a cloud platform, a team uses Git LFS to manage large binary files. Which command is used to start tracking a new large file for version control?

Explanation: The 'git lfs track' command is specifically used to add a file to Git LFS tracking, which is essential for managing large files in cloud-based projects where traditional Git might not handle them efficiently.

Q6. In a cloud-based CI/CD pipeline, which Git branch is commonly used as the source for automated deployments?

Explanation: The 'main' branch is typically used for automated deployments in cloud CI/CD pipelines as it represents the stable production-ready code. Other branches like 'develop' or 'staging' are used for testing or development purposes.

Q7. After configuring a post-receive hook in a cloud-based Git repository to automate deployments, a developer pushes code but the deployment fails. The hook logs indicate it executed but didn't trigger the deployment. What should be checked first?

Explanation: Even though the hook executed, syntax errors in the script could prevent deployment commands from running correctly. Other options relate to permissions or network, which are less likely if the hook ran successfully.

Q8. In a DevOps workflow using Git, which command is used to push your local commits to a remote cloud repository to trigger a continuous integration build?

Explanation: The 'git push' command uploads local commits to a remote repository, which in a CI/CD pipeline can initiate automated builds and deployments.

Q9. In a cloud-native CI/CD pipeline, which Git hook is most appropriate to execute a Terraform apply command after a successful commit to the main branch?

Explanation: The post-receive hook is a server-side hook that executes after a successful push to a repository, making it suitable for triggering a Terraform apply in a cloud-native CI/CD pipeline when changes are pushed to the main branch. Pre-commit and post-commit are client-side hooks (run before/after a local commit), and pre-push runs before pushing to a remote, none of which align with the requirement to act after a commit has been integrated into the main branch.

Q10. In a cloud-based CI/CD pipeline, which Git command is used to push local commits to a remote repository to trigger automated deployment workflows?

Explanation: The 'git push' command sends local changes to a remote repository, which can activate webhooks or CI/CD triggers in cloud platforms like AWS CodePipeline or GitHub Actions.
