Which of the following best describes the main advantage of using Alibaba Cloud CDN?

Alibaba Cloud Content Delivery Network (CDN) caches static and dynamic content onto edge nodes distributed globally. When a user requests content, the request is directed to the optimal edge node closest to the user, significantly reducing network latency, preventing origin server congestion, and ensuring high availability and accelerated content delivery.

A: Alibaba Cloud CDN decreases latency by serving content closer to end users, rather than increasing it.

B: CDN offloads bandwidth and reduces origin server load, optimizing operational costs rather than increasing storage costs.

C: CDN expands geographic reach globally through a vast distributed network of edge locations.
