- A
AWS Global Accelerator
Why wrong: AWS Global Accelerator improves the performance of TCP and UDP applications by directing traffic over the AWS global network, but it does not cache content. It still forwards requests to the origin, so it would not reduce the number of direct requests to the S3 bucket or provide the same latency reduction as a CDN.
- B
Amazon CloudFront
Amazon CloudFront is a content delivery network (CDN) that caches static content at edge locations worldwide. This reduces latency by serving content from a nearby edge location and reduces the number of direct requests to the S3 bucket, thereby offloading the origin.
- C
Amazon Route 53 latency-based routing
Why wrong: Amazon Route 53 latency-based routing directs users to the AWS endpoint with the lowest latency (e.g., an S3 bucket in a specific region). However, each request still goes to the S3 bucket, and the user may still experience latency due to the distance from the bucket. It does not cache content.
- D
AWS Direct Connect
Why wrong: AWS Direct Connect provides a dedicated private network connection from an on-premises data center to AWS. It does not improve latency for global users accessing the website over the public internet, nor does it reduce requests to the S3 bucket.
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 static website on Amazon S3. Users in different geographic locations experience high latency when accessing the website. The company wants to reduce latency for all users and also minimize the number of direct requests to the S3 bucket. Which AWS service should the company use?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue:
"minimum / minimize"Why it matters: Asks for the least resource use — fewest addresses, smallest subnet, lowest overhead. Eliminate over-provisioned options even if they would technically work.
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 content at edge locations worldwide, significantly reducing latency for users regardless of their geographic location. By serving content from the edge, CloudFront also offloads direct requests to the S3 bucket, reducing the load on the origin and potentially lowering costs.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
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
AWS Global Accelerator improves the performance of TCP and UDP applications by directing traffic over the AWS global network, but it does not cache content. It still forwards requests to the origin, so it would not reduce the number of direct requests to the S3 bucket or provide the same latency reduction as a CDN.
- ✓
Amazon CloudFront
Why this is correct
Amazon CloudFront is a content delivery network (CDN) that caches static content at edge locations worldwide. This reduces latency by serving content from a nearby edge location and reduces the number of direct requests to the S3 bucket, thereby offloading the origin.
Clue confirmation
The clue word "minimum / minimize" in the question point toward this answer.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse AWS Global Accelerator (which optimizes network path but does not cache) with CloudFront (which caches content at the edge), leading them to choose Global Accelerator for a static website latency problem.
Detailed technical explanation
How to think about this question
CloudFront uses a global network of over 600 Points of Presence (PoPs) to cache static assets like HTML, CSS, and images, serving them from the nearest edge location via HTTP/HTTPS. It supports origin shield to further reduce load on the S3 bucket by aggregating requests at a regional caching layer before hitting the origin. In a real-world scenario, a global e-commerce site using CloudFront can see latency drop from 300ms to under 50ms for users in remote regions.
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 startup's cloud architect reviews their monthly bill and notices costs are higher than expected for a long-running batch job. Switching from on-demand instances to Reserved Instances — or using Spot/Preemptible VMs — can reduce compute costs by up to 72 %. Questions like this test whether you understand the tradeoffs between commitment, flexibility, and cost across cloud pricing models.
