DevOps / Github Interview questions

What are the main features of GitHub?

GitHub's feature set centers on a handful of core areas that cover most of the collaborative development workflow.

  1. Repositories - Git hosting, branches, and pull requests for code review.
  2. GitHub Actions - CI/CD workflows defined in YAML, triggered by repository events.
  3. Issues and Projects - lightweight issue tracking and Kanban-style project boards.
  4. GitHub Packages - a hosted package/container registry per repository or organization.
  5. Security features - Dependabot alerts, secret scanning, and code scanning.
  6. GitHub Pages - free static site hosting straight from a repository.
  7. Codespaces - cloud-hosted development environments launched directly from a repo.

Which of these are available for free versus which require a paid plan depends on the account type (personal vs. organization) and plan tier; core features like unlimited public/private repos and a baseline amount of Actions minutes are included even on the Free plan.

Which of these is a built-in GitHub feature?
