What is the primary function of a Content Delivery Network (CDN) in web infrastructure?

Options:

Encrypt web traffic end-to-end
Cache and deliver content from edge servers close to users
Translate domain names to IP addresses
Manage user authentication and sessions

Correct answer: Cache and deliver content from edge servers close to users

Explanation: A CDN caches static and dynamic content on geographically distributed edge servers to reduce latency and bandwidth use. For example, Akamai popularized CDNs after its 1998 founding to speed global content delivery.
