- A
Use AWS Global Accelerator with endpoints pointing to the S3 bucket.
Why wrong: Global Accelerator improves network routing but does not cache content; CloudFront is the appropriate CDN.
- B
Deploy EC2 instances in multiple Regions and use a load balancer.
Why wrong: This adds complexity and cost; CloudFront is simpler and cost-effective for static content.
- C
Use Amazon CloudFront with the S3 bucket as the origin.
CloudFront caches content at edge locations, reducing latency and data transfer costs.
- D
Host the content directly from the S3 bucket and use S3 Transfer Acceleration.
Why wrong: Transfer Acceleration speeds up uploads, not downloads; it does not cache content globally.

SAP-C02 Design for New Solutions Practice Question
This SAP-C02 practice question tests your understanding of design for new solutions. 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 wants to serve static content (images and videos) to users worldwide with low latency. The content is stored in an Amazon S3 bucket. What is the most cost-effective solution?
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
✓
Use Amazon CloudFront with the S3 bucket as the origin.
Amazon CloudFront is a global content delivery network (CDN) that caches static content at edge locations worldwide, reducing latency for users. Using an S3 bucket as the origin is cost-effective because CloudFront egress costs are often lower than direct S3 data transfer, and you only pay for data transfer out from CloudFront and occasional origin fetches. This solution minimizes origin load and provides low-latency delivery without the overhead of managing servers or additional acceleration services.
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.
- ✗
Use AWS Global Accelerator with endpoints pointing to the S3 bucket.
Why it's wrong here
Global Accelerator improves network routing but does not cache content; CloudFront is the appropriate CDN.
- ✗
Deploy EC2 instances in multiple Regions and use a load balancer.
Why it's wrong here
This adds complexity and cost; CloudFront is simpler and cost-effective for static content.
- ✓
Use Amazon CloudFront with the S3 bucket as the origin.
Why this is correct
CloudFront caches content at edge locations, reducing latency and data transfer costs.
Related concept

- ✗
Host the content directly from the S3 bucket and use S3 Transfer Acceleration.
Why it's wrong here
Transfer Acceleration speeds up uploads, not downloads; it does not cache content globally.
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 like CloudFront, or mistakenly think S3 Transfer Acceleration improves download performance for end users when it only accelerates uploads to S3.
Detailed technical explanation
How to think about this question
CloudFront uses a global network of over 600 Points of Presence (PoPs) to cache static objects at the edge, serving content from the nearest location to the user. Under the hood, CloudFront supports HTTP/2 and HTTP/3, connection keep-alive, and origin shield to reduce load on the S3 bucket, while S3 Transfer Acceleration is designed for upload optimization using edge locations but does not cache responses. In a real-world scenario, a media streaming platform would use CloudFront with S3 to serve millions of video requests with minimal latency, whereas Global Accelerator would be chosen for dynamic content or non-HTTP protocols like UDP gaming traffic.
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.
