CLF-C02 Cloud Technology and Services Practice Question
A company hosts a website in the US East (N. Virginia) AWS region. Users in Europe and Asia Pacific report slow page load times because content must travel long distances from the origin server. Which AWS service should the company deploy to reduce latency for global users?
⚠ Common exam trap
It's easy for candidates to confuse latency-based routing (Route 53) with content caching (CloudFront), mistakenly thinking that routing traffic to a different region solves the problem of content traveling long distances, when in fact only a CDN reduces the physical distance by serving cached content from edge locations.
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 content delivery network (CDN) that caches static and dynamic content at edge locations worldwide, including Europe and Asia Pacific. By serving content from the edge location closest to each user, CloudFront significantly reduces latency and improves page load times for global users without requiring changes to the origin infrastructure.
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 Direct Connect
Why it's wrong here
Direct Connect provides a dedicated private network link between an on-premises data centre and AWS, so it cannot cache content or serve European and Asian users closer to their location. It is tempting because it reduces latency and improves bandwidth for hybrid workloads, but that applies to private connectivity from a fixed site, not global public web delivery.
- ✗
Amazon Route 53 with latency routing
Why it's wrong here
Route 53 latency routing directs users to the AWS region with the lowest latency, but this requires the company to deploy infrastructure in multiple regions. It routes to existing endpoints; it does not cache content.
- ✓
Amazon CloudFront
Why this is correct
CloudFront is a CDN that caches static and dynamic content at 400+ edge locations globally. A user in Europe would be served cached content from a nearby edge location instead of making a round-trip to US East, dramatically reducing latency.
- ✗
Amazon VPC peering
Why it's wrong here
VPC peering connects two VPCs over the private AWS backbone, so it does not place content nearer to European or Asian users. It is tempting because it reduces latency between VPCs, but that applies to private inter-VPC traffic within AWS, not to caching public website content at edge locations.
