What is the primary purpose of a Content Delivery Network (CDN) in collaboration systems delivering global content?

• A. Stores all data in a single central data center for consistency.
• B. Encrypts data only at rest, not in transit.
• C. A Content Delivery Network caches content at edge locations to reduce latency and improve performance worldwide.
• D. Replaces user authentication with local sessions.

Answer: (C)

Content Delivery Networks exist to move content closer to users by caching copies at edge servers around the world. This cuts down the distance data must travel, so requests are served faster, which is crucial for collaboration tools that need quick access to documents, media, and live features globally. It also helps scale and improve reliability by offloading traffic from central servers. Security and authentication are separate concerns, so a CDN doesn’t replace user authentication and it doesn’t imply all data is kept in one central data center. In short, caching at edge locations to reduce latency and improve worldwide performance is the core benefit.
