About This Topic

Deployment is the process of moving a finished web app onto servers that users can reach, and hosting is the service that keeps it running and accessible. Questions compare shared hosting, VPS, dedicated servers and cloud platforms, plus static hosting options such as GitHub Pages, Netlify and Vercel. Know how CI/CD pipelines automate build, test and release, how Docker containers package an app with its dependencies, and what Kubernetes adds through orchestration, scaling and health checks. Release strategies such as rolling, blue-green and canary deployments are frequently compared, along with DNS configuration, SSL certificates, environment variables and rollbacks.

Below are 30 practice questions from a pool of 210 Deployment & Hosting MCQs, one of 17 topics in Web Development. Each shows the correct answer with an explanation; when you are ready, take a timed quiz to test recall under exam conditions.
