CompTIA Cloud Essentials+ (CLO-002)Cloud ConceptsEasy
A global software company is deploying a new web application that needs to serve users worldwide. To minimize latency and improve user experience, the company wants to cache static content (images, CSS, JavaScript) closer to its end-users. Which cloud networking service is best suited for this purpose?
- ADirect Cloud Connect
- BVirtual Private Cloud (VPC)
- CContent Delivery Network (CDN)
- DVirtual Private Network (VPN)
Show answer & explanationAnswer & explanation
Correct answer: C. Content Delivery Network (CDN)
A Content Delivery Network (CDN) is specifically designed to cache static and dynamic content at edge locations geographically closer to users. This significantly reduces latency and improves the performance of web applications for a globally distributed user base.
Why the other options are wrong
- A. Direct Cloud Connect provides dedicated private network connectivity to a cloud region, not global content caching.
- B. VPC provides an isolated network environment within a cloud, not content caching at edge locations.
- D. A VPN provides secure, encrypted network connectivity, but does not cache content or optimize delivery speed for global users.
Content Delivery Network (CDN)
A geographically distributed network of proxy servers and their data centers used to deliver content to users based on their geographic location, improving speed and performance.
- Caches static and dynamic content at edge locations.
- Reduces latency and improves user experience.
- Offloads traffic from origin servers.
Memory trick: Networking: CDN for speed, VPC for isolation, VPN for security, Direct for dedicated.
