Quizplus · Accepted Answer

Choice B is incorrect because CDNs do replicate data across multiple servers. Choice C is partially correct but ignores other factors such as network congestion and server availability that CDNs also consider. Choice D is incorrect as CDNs use various algorithms to dynamically route traffic to the most optimal server.
