What is commonly a benefit of using a CDN?

Using a Content Delivery Network (CDN) commonly results in reduced website load times. This enhancement is mainly due to the way CDNs distribute content across a network of geographically dispersed servers. When a user requests content, the CDN delivers it from the closest server to the user's location, minimizing latency and ensuring faster response times.

Furthermore, CDNs optimize the delivery of static assets, such as images, CSS, and JavaScript files, allowing them to load more quickly than if they were being served from a single origin server that may be far away from the user. This not only improves the user experience by providing quick access to content but can also lead to better SEO performance, as site speed is a factor in search engine rankings.

In contrast to the correct answer, increased server requirements, limited accessibility of content, and dependency on local data centers are not benefits of using a CDN. Instead, a CDN actually relieves the load on a single server, allows global access to content, and decentralizes data, providing a more robust solution for content delivery.
