What is the primary purpose of a Content Delivery Network (CDN)?

• A. Allows for the quick transfer of assets needed for loading internet content.
• B. Stores full backups of databases in a separate site.
• C. Provides virtual desktop infrastructure.
• D. Manages user authentication across multiple services.

Answer: (A)

CDNs are designed to deliver web content quickly by placing copies of assets on servers distributed around the world. The primary purpose is to reduce latency and bandwidth usage by serving assets from a location close to the user, so web pages and apps load faster. This caching of static resources like images, scripts, stylesheets, and media at edge servers also helps handle traffic spikes and lightens the load on the origin server.

That’s why the answer focuses on enabling the quick transfer of assets needed for loading internet content. The other options describe different IT concepts—backup storage for disaster recovery, virtual desktop infrastructure, and cross-service authentication—which aren’t the CDN’s primary role.
