Which of the following does this feature replicate to the destination S3 bucket by default?
Objects in the source S3 bucket for which the bucket owner does not have permissions
Objects that are stored in S3 Glacier
Objects that existed before replication was configured
Object metadata
Explanations:
Cross-Region Replication (CRR) only replicates objects that the source bucket owner has permission to replicate. If the source bucket owner doesn’t have the required permissions, replication will not occur.
Amazon S3 Cross-Region Replication does not replicate objects that are stored in S3 Glacier or Glacier Deep Archive. Only objects in standard storage classes (e.g., S3 Standard, S3 Intelligent-Tiering, etc.) can be replicated.
Cross-Region Replication only applies to objects created after the replication configuration is set up. Objects that existed before replication was configured are not replicated unless explicitly copied.
By default, Cross-Region Replication replicates both the objects and their metadata (e.g., object size, last modified time) to the destination bucket.
I evaluate that the answer is:
Object metadata
