How does a Content Delivery Network (CDN) improve website performance?

By increasing server storage
By redirecting traffic to the closest caching server
By hosting all user data in one location
By creating multiple user accounts

The correct answer is: By redirecting traffic to the closest caching server

A Content Delivery Network (CDN) significantly enhances website performance primarily by redirecting traffic to the closest caching server. When a user requests content from a website, the CDN directs that request to the nearest edge server, which holds a cached version of the website's static content, such as images, stylesheets, and scripts. This geographical proximity reduces latency, as the data travels a shorter distance, leading to faster loading times. Additionally, CDNs distribute the load of delivering content, which helps in balancing the demand across multiple servers. This not only speeds up access for users but also enhances reliability and availability, especially during traffic spikes. By minimizing the time it takes for content to travel from the server to the user, CDNs play a crucial role in optimizing the overall performance of a website. The other options do not contribute to the primary function of a CDN. Increasing server storage is related to capacity rather than performance, hosting all user data in one location could lead to delays, and creating multiple user accounts does not affect website performance in the context of content delivery.
