Topic 1 Question 227
A company provides auction services for artwork and has users across North America and Europe. The company hosts its application in Amazon EC2 instances in the us-east-1 Region. Artists upload photos of their work as large-size. high-resolution image files from their mobile phones to a centralized Amazon S3 bucket created in the us-east-1 Region. The users in Europe are reporting slow performance for their image uploads.
How can a solutions architect improve the performance of the image upload process?
Redeploy the application to use S3 multipart uploads.
Create an Amazon CloudFront distribution and point to the application as a custom origin.
Configure the buckets to use S3 Transfer Acceleration.
Create an Auto Scaling group for the EC2 instances and create a scaling policy.

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.

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.
