Which statement about CDN points of presence (PoPs) is true?

Which statement about CDN points of presence (PoPs) is true?

• A. PoPs are only located in the origin server's location.
• B. PoPs replace the origin server entirely.
• C. PoPs include caching servers that help deliver content to website visitors within its operational proximity.
• D. PoPs do not affect content delivery speed.

Answer: (C)

CDN PoPs are edge locations equipped with caching servers that bring content closer to users. By storing copies of static assets and frequently requested content near the end users, the CDN can deliver to visitors from a nearby edge rather than forcing every request to travel all the way to the origin. This proximity reduces latency, speeds up delivery, and lowers the load on the origin server. If the requested content is already cached at a nearby PoP (a cache hit), it’s served quickly; if not (a cache miss), the edge fetches it from the origin and then caches it for future requests. PoPs are not meant to replace the origin; they work alongside it to improve performance and reliability. They also do affect delivery speed, which is part of their primary purpose. The statement that best describes PoPs is that they include caching servers that help deliver content to website visitors within their operational proximity.
