Topic 1 Question 71
2 つ選択A video streaming company recently launched a mobile app for video sharing. The app uploads various files to an Amazon S3 bucket in the us-east-1 Region. The files range in size from 1 GB to 10 GB.
Users who access the app from Australia have experienced uploads that take long periods of time. Sometimes the files fail to completely upload for these users. A solutions architect must improve the app’s performance for these uploads.
Which solutions will meet these requirements?
Enable S3 Transfer Acceleration on the S3 bucket. Configure the app to use the Transfer Acceleration endpoint for uploads.
Configure an S3 bucket in each Region to receive the uploads. Use S3 Cross-Region Replication to copy the files to the distribution S3 bucket.
Set up Amazon Route 53 with latency-based routing to route the uploads to the nearest S3 bucket Region.
Configure the app to break the video files into chunks. Use a multipart upload to transfer files to Amazon S3.
Modify the app to add random prefixes to the files before uploading.

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.

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.
