Question

Organization ABC has a customer base in the US and Australia that would be downloading 10s of GBs files from your application. For them to have a better download experience, they decided to use the AWS S3 bucket with cross-region replication with the US as the source and Australia as the destination. They are using existing unused S3 buckets and had set up cross-region replication successfully. However, when files uploaded to the US bucket, they are not being replicated to Australia bucket. What could be the reason?

A. Versioning is not enabled on the source and destination buckets.

B. Encryption is not enabled on the source and destination buckets.

C. Source bucket has a policy with DENY and the role used for replication is not excluded from DENY.

D. Destination bucket’s default CORS policy does not have source bucket added as the origin.

Answer 1

C. Source bucket has a policy with DENY and the role used for replication is not excluded from DENY.

For option A, Cross region replication cannot be enabled without enabling versioning. The question states that cross-region replication has been successfully enabled. So this option is not correct.
