Which hosting technique enables multiple domains to be served from the same server, enabling resource sharing across a global company?

• A. Content Delivery Network
• B. DNS Hosting
• C. Virtual Hosting
• D. Cloud Storage

Answer: (C)

Virtual hosting allows a single server to serve multiple domain names, sharing the same hardware and resources. The web server uses the Host header from each incoming request (and its configuration blocks, like VirtualHost or server_name) to decide which site’s content to deliver. This lets a global company run many brands or regional sites on one physical machine or cluster, simplifying management and reducing hardware costs while keeping each site’s data and settings isolated. There are two common forms: name-based virtual hosting, where multiple domains share one IP, and IP-based hosting, where each domain has its own IP. For HTTPS, you’d typically use SNI to present the right certificate for each domain on a single IP, or assign separate IPs/certificates as needed. This matches the idea of serving multiple domains from the same server and enabling resource sharing across the organization. The other options don’t fit: a Content Delivery Network focuses on delivering content from edge locations to users; DNS hosting maps domain names to IP addresses but doesn’t host multiple sites on one server; cloud storage is about storing and retrieving files, not hosting multiple web domains from a single server.
