Question 17
Domain 4: Accelerate Workload Migration and ModernizationA 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' performance for these uploads Which solutions will meet these requirements? (Select TWO.)
Correct answer: C
Explanation
Amazon S3 Transfer Acceleration uses CloudFront edge locations to speed up uploads over long distances, which helps users in Australia upload to a bucket in "us-east-1" faster and with fewer failures. For 1 GB to 10 GB files, multipart upload is also required because it lets large objects upload in parts and resume failed transfers, improving reliability and performance.
Why each option is right or wrong
A. Enable S3 Transfer Acceleration on the S3 bucket Configure the app to use the Transfer Acceleration endpoint for uploads
Transfer Acceleration helps distance-related latency, but alone does not add multipart retry resilience for huge files.
B. Configure the app to break the video files into chunks Use a multipart upload to transfer files to Amazon S3.
Multipart upload improves large-file reliability, but alone does not optimize long-distance network paths from Australia.
C. All of the above
Each of the listed options is a valid answer; all are needed.
