Question

Quizplus · Accepted Answer

CDNs reduce users' access costs by delivering data faster through caching content on servers located closer to the end-user. This reduces the distance the data needs to travel and therefore reduces access costs. Option B is incorrect because CDNs replicate content on different servers to ensure quicker delivery and higher availability. Option C is partially correct as CDNs use algorithms and routing to determine the optimal server to deliver content from, which is not necessarily the closest geographically but rather the server with the best performance. Option D is incorrect as decisions on which server to use for content delivery are made in real-time and are based on factors such as server load and network conditions, not on an hourly basis.
