Question 1mediummultiple choice
Full question →mediummultiple choiceObjective-mapped
A media company has users around the world uploading 1 to 5 GB files directly to a single Amazon S3 bucket. Upload times are slow from distant regions, but the app must keep using S3 as the destination. What should the architects enable to improve upload performance?
Answer choices
Why each option matters
Good practice is not just finding the correct option. The wrong answers often show the exact trap the exam wants you to fall into.
A
Distractor review
Amazon CloudFront for origin caching of uploaded files.
CloudFront is primarily used to cache and accelerate downloads and web content delivery. It is not the standard solution for speeding up direct uploads to S3 from distant users. While it can sit in front of origins, the better fit for improving upload performance to S3 is a feature that optimizes the upload path itself.
B
Best answer
Amazon S3 Transfer Acceleration on the bucket.
S3 Transfer Acceleration improves upload performance over long distances by routing traffic through AWS edge locations and optimized network paths to the target bucket. This is a strong fit for globally distributed users uploading large files directly to S3. It preserves the same storage destination while making the transfer path faster and more consistent for remote clients.
C
Distractor review
Provisioned IOPS EBS volumes attached to a transfer server.
Provisioned IOPS EBS volumes help block storage performance on EC2 instances, but they do not directly solve a global S3 upload bottleneck. The requirement is about clients uploading to S3 from distant regions, not about local disk throughput on an intermediate server. This option changes the wrong part of the architecture.
D
Distractor review
Amazon EFS with a mount target in each Region.
EFS is a shared file system, not an object storage destination for internet uploads. It does not replace S3 for this use case and would not solve the long-distance upload challenge. The workload needs faster delivery into S3 itself, which is why a transfer acceleration feature is more appropriate.
Common exam trap
Common exam trap: NAT rules depend on direction and matching traffic
NAT is not only about the public address. The inside/outside interface roles and the ACL or rule that matches traffic are just as important.
Technical deep dive
How to think about this question
NAT questions usually test address translation, overload/PAT behaviour, static mappings and whether the right traffic is being translated. Read the interface direction and address terms carefully.
KKey Concepts to Remember
- Static NAT maps one inside address to one outside address.
- PAT allows many inside hosts to share one public address using ports.
- Inside local and inside global describe the private and translated addresses.
- NAT ACLs identify traffic for translation, not always security filtering.
TExam Day Tips
- Identify inside and outside interfaces first.
- Check whether the scenario needs static NAT, dynamic NAT or PAT.
- Do not confuse NAT matching ACLs with normal packet-filtering intent.

FAQ
Questions learners often ask
What does this SAA-C03 question test?
Static NAT maps one inside address to one outside address.
What is the correct answer to this question?
The correct answer is: Amazon S3 Transfer Acceleration on the bucket. — S3 Transfer Acceleration is the best answer because it is purpose-built for speeding up uploads to S3 from geographically distant clients. It uses AWS edge infrastructure to reduce the network distance that the upload traffic must travel before reaching the destination bucket. Since the company must continue storing the data in S3, this option improves performance without changing the target service or application flow. Why others are wrong: CloudFront is more suitable for caching downloads than for accelerating direct S3 uploads. EBS volumes improve local block storage performance on EC2, but they do not address the end-to-end upload path from global users. EFS is a shared file system and not a replacement for S3 object ingest. The scenario specifically calls for faster uploads to S3, which Transfer Acceleration provides.
