Your organization is planning to upload a large number of files to the AWS cloud. These files need to be immediately available for download across different geographical regions right after the upload is complete. They consulted you to check if S3 is a suitable solution for the use case. What do you suggest?

Answer options:

A.S3 is not suitable for immediate downloads because new AWS provides eventual consistency for new objects.
B.EFS is not suitable for immediate downloads because AWS provides eventual consistency for new objects.
C.EFS is suitable for immediate downloads because AWS provides eventual consistency for new objects.
D.S3 is suitable for immediate downloads because AWS provides strong read-after-write consistency for new objects.

Answer: D
Amazon S3 provides strong read-after-write consistency for PUTS of new objects in your S3 bucket in all regions. There is a new update mentioned in https://aws.amazon.com/blogs/aws/amazon-s3-update-strong-read-after-write-consistency/.
Option C is not true. EFS provides strong read-after-write consistency.
