Question
A web application was deployed, and files are available globally to improve user experience. Which of the following technologies is being used?
- A. SAN
- B. CDN Correct
- C. VDI
- D. API
Explanation
A content delivery network (CDN) caches an application's files at edge locations around the world so users download them from a nearby server, reducing latency and improving the user experience. A SAN is block storage for servers in a data center, VDI delivers virtual desktops, and an API is an interface for programmatic access; none of them distribute content globally.
