CLF-C02 Cloud Technology and Services Practice Question
Which AWS service provides a fully managed content delivery network (CDN) that caches content at global edge locations to reduce latency for end users?
⚠ Common exam trap
Test-takers frequently confuse AWS Global Accelerator (a network optimization service) with a CDN, because both use edge locations, but Global Accelerator does not cache content—it only optimizes network routing.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Amazon CloudFront
Amazon CloudFront is a fully managed content delivery network (CDN) that caches static and dynamic content at global edge locations. By serving cached content from the edge closest to the user, CloudFront significantly reduces latency and improves data transfer speeds for end users.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
AWS Global Accelerator
Why it's wrong here
This service uses AWS's global network infrastructure to route user traffic through the most optimal path to application endpoints. It improves connection quality by reducing hop count and using static IP addresses, but it does not store or cache content at edge locations. It provides network-level traffic management, not content-level caching.
- ✗
Amazon Route 53
Why it's wrong here
Amazon's DNS service resolves domain names and can perform latency-based or geo-based routing to send users to a healthy endpoint. While it can direct traffic to the nearest available resource, it does not cache any web content or media. DNS resolution only maps to IP addresses; all content remains on the origin, so it is not a CDN.
- ✓
Amazon CloudFront
Why this is correct
As AWS's content delivery network, CloudFront uses a global network of 400+ edge locations to cache static and dynamic content closer to viewers. When a user requests content, CloudFront serves it from the nearest edge location, reducing latency and offloading origin servers. It supports both static caching and dynamic content acceleration via the AWS backbone.
- ✗
AWS Transfer Acceleration
Why it's wrong here
This is an AWS service that accelerates uploading files to S3 buckets over long distances using AWS edge locations. It does not cache or deliver content to end users for download; instead, it optimizes the upload path to Amazon S3. Its purpose is to speed up transfers from a client into AWS, not to serve content as a CDN.
