Exam AWS Certified Solutions Architect - Professional SAP-C02 topic 1 question 227 discussion

Main point of the question: "The users in Europe are reporting slow performance for their image uploads." How do we improve performance? If we look on the latency side, sure, S3 Transfer Acceleration (option C), but the question puts another variable to our scenario: "Artists upload photos of their work as large-size. high-resolution image files from their mobile phones..." If you just look at that above, you would switch to A as we can improve upload with multipart. Here comes the plot twist "The users in Europe are reporting slow performance for their image uploads." - Meaning, in "Europe", not in the "NA". Of course! The bucket in the US... So yeah, question really bad, not objective (in my pov) and with lots of interpretations, but C would help them with the perception of performance in this context.

Between A and C, I would choose C - Transfer Acceleration, as this issue is focusing on improving the upload performance across the region

Why not B ?

Option C. As the users in Europe only are facing this issue. A would improve upload performance overall for both US and Europe.

I believe this question should rightfully be a multi-choice question where A and C are the answer together to solve this problem statement https://aws.amazon.com/blogs/compute/uploading-large-objects-to-amazon-s3-using-multipart-upload-and-transfer-acceleration/

I would choose A. Why does C say "Configure the buckets [more than one] to use S3 Transfer Acceleration? Sometimes you have to hate how these questions and answers are worded.

I have some doubts about this question, it makes more sense to use multipart upload to split the file and gain upload speed. AWS Transfer Accelerator seems to be applied to reduce delay.http s://aws.amazon.com/pt/blogs/compute/uploading-large-objects-to-amazon-s3-using-multipart-upload-and-transfer-acceleration/

Correct C.

C would be good in combination with A, but better as a standalone choice

upload performance-> transfer acceleration

correct is C

Transfer Acceleration doesn't guarantee a significant increase in upload speed. A multi-part upload on other hand does, because it uploads multiple smaller chunks of the files in parallel. Ideally multi-part upload and Transfer Accelerator should be deployed together. If we had to pick only one of the two, multi-part upload would result in better performance. https://aws.amazon.com/blogs/compute/uploading-large-objects-to-amazon-s3-using-multipart-upload-and-transfer-acceleration/

C. https://aws.amazon.com/s3/transfer-acceleration/

C of course

C - Transfer acceleration. S3 Transfer Acceleration utilizes the Amazon CloudFront global network of edge locations to accelerate the transfer of data to and from S3 buckets. By enabling S3 Transfer Acceleration on the centralized S3 bucket, the users in Europe will experience faster uploads as their data will be routed through the closest CloudFront edge location.
