What does the Azure Content Delivery Network (CDN) primarily help with?

Storage of large files
Quick access to data within different regions
Improving load times for delivering web content
Securing data in transit

The correct answer is: Improving load times for delivering web content

The Azure Content Delivery Network (CDN) primarily enhances internet experiences by improving load times for delivering web content. It achieves this by distributing content across a network of strategically positioned servers, allowing users to access data from a location that is closer to them geographically. This process reduces latency and improves the speed at which content, such as images, videos, and scripts, is delivered to end-users. The CDN caches static and dynamic content in various edge locations, and when a user requests that content, the CDN can serve it directly from the nearest edge server rather than from the origin server. This not only speeds up access but also alleviates the load on the origin server, reducing the chances of downtime and improving reliability. While the other options mention valid aspects related to data and performance, they do not focus on the primary purpose of a CDN. For example, while Azure does provide solutions for storage, quick access to data across regions, and security, these functions are not the main features associated with CDN services, which are specifically geared toward optimizing the delivery of web content.
