A company delivers on-demand training videos stored in an S3 bucket in us-east-2. The company created S3 buckets in eu-west-2 and ap-southeast-1 and wants to replicate data to them. The goal is to minimize latency for developers who upload videos and for students who stream videos near eu-west-2 and ap-southeast-1 while making the FEWEST application changes. Which combination of steps meets these requirements? (Choose two.)

Correct answer: Configure two-way (bidirectional) replication among the S3 buckets that are in all three Regions., Create an S3 Multi-Region Access Point. Modify the application to use the Amazon Resource Name (ARN) of the Multi-Region Access Point for video streaming and uploads..
Why this is the answer
To minimize latency for both uploads and streams across multiple regions with fewest application changes, bidirectional replication and an S3 Multi-Region Access Point are key. Bidirectional replication ensures all buckets eventually contain all data, so developers uploading to any region will have their content replicated everywhere. An S3 Multi-Region Access Point provides a single global endpoint that automatically routes requests to the nearest S3 bucket, optimizing latency for both uploads and streams without requiring complex application logic to determine the closest region. Incorrect options: One-way replication from a single source bucket would mean uploads to other regions wouldn't be replicated back to the source or other target regions, failing to meet the "minimize latency for developers who upload" requirement across all regions. Modifying the application for only streaming with a Multi-Region Access Point, but not uploads, would mean uploads still go to a single bucket, negating latency benefits for developers.
