- A
Amazon CloudFront
Correct. CloudFront is a global CDN that caches static assets at edge locations, reducing latency and origin load.
- B
AWS Global Accelerator
Why wrong: Incorrect. Global Accelerator improves performance for TCP/UDP traffic by routing it over the AWS global network and providing anycast IPs, but it does not cache content. It still requires each request to reach the origin server.
- C
Amazon Route 53 with latency-based routing
Why wrong: Incorrect. Latency-based routing directs users to the AWS region that offers the lowest latency, but the content is still served from the origin EC2 instance. It does not cache content at edge locations.
- D
Amazon S3 Transfer Acceleration
Why wrong: Incorrect. S3 Transfer Acceleration speeds up uploads of objects to an S3 bucket from remote clients by using AWS edge locations. It is designed for upload to a specific bucket, not for caching and serving content to end users.
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 its website on a single Amazon EC2 instance in the us-east-1 Region. The website includes static assets such as images, CSS, and JavaScript files. Users in Europe and Asia report that the website loads slowly because the static assets must travel from the us-east-1 Region. The company wants to reduce latency for global users and decrease the load on the EC2 instance by serving static content from locations that are closer to the users. Which AWS service should the company use to meet these requirements?
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 assets (images, CSS, JavaScript) at edge locations worldwide. By serving content from edge locations closer to users in Europe and Asia, CloudFront reduces latency and offloads requests from the origin EC2 instance, decreasing its load. This directly meets the requirements for global latency reduction and reduced EC2 load.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Amazon Route 53 with latency-based routing
Why it's wrong here
Incorrect. Latency-based routing directs users to the AWS region that offers the lowest latency, but the content is still served from the origin EC2 instance. It does not cache content at edge locations.
- ✗
Amazon S3 Transfer Acceleration
Why it's wrong here
Incorrect. S3 Transfer Acceleration speeds up uploads of objects to an S3 bucket from remote clients by using AWS edge locations. It is designed for upload to a specific bucket, not for caching and serving content to end users.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates confuse AWS Global Accelerator (which optimizes network path but does not cache) with a CDN, or think Route 53 latency-based routing alone can serve content from edge locations, when in fact it only directs traffic to the same single origin.
Detailed technical explanation
How to think about this question
CloudFront uses a global network of over 600 Points of Presence (PoPs) to cache static content via HTTP/HTTPS, reducing round-trip time (RTT) for users. Under the hood, CloudFront supports origin shield to further reduce load on the origin, and it can integrate with AWS WAF for security. A real-world scenario: a media company serving high-resolution images globally would see a 60-80% reduction in origin requests and latency improvements from 300ms to under 50ms for distant users.
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 media company stores terabytes of video archives that are accessed once a year for audit purposes. Moving these objects to a cold storage tier (Azure Archive, S3 Glacier, or Google Nearline) costs a fraction of hot storage. Questions like this test whether you understand storage tiers, access frequency tradeoffs, and retrieval latency requirements.
