Transfer Accelerator + Multi-part uploads for files more 500MB

Explanation for this . B: Configuring an S3 bucket in each Region to receive the uploads and using S3 Cross-Region Replication to copy the files to the distribution S3 bucket may improve data durability and availability, but it does not address the issue of slow uploads from Australia. C: Amazon Route 53 with latency-based routing can route the uploads to the nearest S3 bucket Region based on network latency, but it cannot guarantee faster upload speeds or better reliability. E: Adding random prefixes to the files before uploading will not improve upload performance or reliability. Thence, I select A and D.

A. Enable S3 Transfer Acceleration on the S3 bucket. Configure the app to use the Transfer Acceleration endpoint for uploads. D. Configure the app to break the video files into chunks. Use a multipart upload to transfer files to Amazon S3.

A = correct (improve upload performance) B = this could work along with C to improve performance, but this will not fix upload failure for files >5GB as you need multi-part upload C = se answer B D = correct (required to fix upload failures for >5GB files) E = this could help with throttling which is not clearly stated as an issue

Answer: A, D? Maybe. But I prefer D and E. Let me explain why: Requirement is: "A solutions architect must improve the app’s performance for these uploads." Should we change S3 or the app? (or both?) Depending on how you interpret this question, you might think on the app, then it should be D and E, seriously. And it DOES make sense. Bear with me here. If you break the files into chunks, you will still have to upload them, let's say 10GB. And here comes the option E, which helps improving uploads with PARALELLISM, and you didn't touch S3 to fix that, just the app :) B and C would also work and would address the issue with users in Australia but it would change their design. I am not sure this is required, but in the real world, it's good to have options ;) All in all, I personally would go with D, E, but AD and BC would also work.

its AD

A and D satisfy the requirement

AD all day

B is not suitable here, since it wants to improve upload experience, not download

I like AD but I am unsure. If the users in US don't complain about issues, it must be because multi-part upload is already enabled, otherwise it would fail 50% of the times. If only Australia users complain, it must be something else... Maybe A+B is a better option, although B is not the most cost efficient certainly.

AD is correct

https://www.examtopics.com/discussions/amazon/view/74177-exam-aws-certified-solutions-architect-professional-topic-1/ The correct answers would be A and D. A. Enabling S3 Transfer Acceleration on the S3 bucket and configuring the app to use the Transfer Acceleration endpoint for uploads will improve the app's performance for users in Australia by providing a fast and secure way to transfer large files over the Internet. D. Configuring the app to break the video files into chunks and using a multipart upload to transfer files to Amazon S3, will improve the app's performance for users in Australia by allowing them to upload large files in parallel, which can increase upload speed and reduce the risk of upload failures.
