14. How do you deploy a static website to Netlify?

    • Answer: You connect your Git repository (GitHub, GitLab, Bitbucket), select the branch to deploy from, and Netlify will automatically build and deploy your website based on your configuration.

15. What is a Netlify site's `_redirects` file used for?

    • Answer: The `_redirects` file defines redirect rules for your website, allowing you to map incoming URLs to different destinations or perform other redirect actions.

    • Answer: Optimizations include using image compression, code splitting, efficient caching strategies, and leveraging Netlify's built-in features like image optimization.

19. Explain Netlify's role in serverless computing.

    • Answer: Netlify provides a serverless platform where you can deploy and manage serverless functions without managing infrastructure. It handles the scaling and execution of these functions automatically.

20. What are some common debugging techniques for Netlify deployments?

    • Answer: Check Netlify's build logs for errors, use browser developer tools to inspect network requests, and review your site's configuration files for mistakes.

21. How does Netlify handle different deployment branches?

    • Answer: Netlify can deploy from different branches, usually having a main branch for production and other branches for previews or staging environments.

22. Describe a situation where you would use Netlify functions over a traditional backend server.

    • Answer: For small, event-driven tasks such as handling form submissions, sending emails, or making simple API requests, Netlify functions are more efficient and cost-effective than setting up and managing a full backend server.
