- A
AWS Direct Connect
Why wrong: Direct Connect provides a dedicated network connection between an on-premises data centre and AWS. It does not cache or serve content to end users globally.
- B
Amazon Route 53 with latency routing
Why wrong: 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.
- C
Amazon CloudFront
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.
- D
Amazon VPC peering
Why wrong: VPC peering connects two VPCs privately within AWS. It does not cache content or reduce latency for public internet users.
Quick Answer
The answer is Amazon CloudFront, a content delivery network (CDN) that reduces latency for global users by caching content at edge locations worldwide. When a company hosts a website in the US East (N. Virginia) region, users in Europe and Asia Pacific experience slow load times because data must traverse long distances across the internet. CloudFront solves this by serving cached copies of static and dynamic content from the edge location geographically closest to each user, dramatically cutting round-trip time and offloading requests from the origin server. On the AWS Certified Cloud Practitioner CLF-C02 exam, this scenario tests your understanding of how CDNs improve performance for global audiences—a common question that contrasts CloudFront with services like AWS Global Accelerator or S3 Transfer Acceleration. A frequent trap is confusing CloudFront with a regional service like an Application Load Balancer; remember that CloudFront’s key differentiator is its distributed edge network. Memory tip: think “CloudFront = closest edge” to instantly recall its role in slashing latency for users anywhere in the world.
CLF-C02 Cloud Technology and Services Practice Question
This CLF-C02 practice question tests your understanding of cloud technology and services. Match the stated requirement to the specific cloud service, access model, or configuration option — many options are valid in isolation but not for this scenario. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
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?
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.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often 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.
Detailed technical explanation
How to think about this question
CloudFront leverages over 600 Points of Presence (PoPs) globally, using HTTP/2 and TCP optimizations like TLS 1.3 and connection reuse to minimize round-trip time. It supports origin shielding to reduce load on the origin server and can cache both static assets (e.g., images, CSS) and dynamic content using Lambda@Edge for customization. In a real-world scenario, a media streaming platform using CloudFront can reduce Time to First Byte (TTFB) from 500ms to under 50ms for users in Asia by serving cached video segments from a nearby edge location.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
TExam Day Tips
- Watch for words such as best, first, most likely and least administrative effort.
- Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A healthcare organisation deploys an application with a public-facing web tier and a private database tier. The database subnet has no public IP and only accepts connections from the web tier's security group. Questions like this test whether you can design cloud network isolation using VNets/VPCs, subnets, and security group rules.
