Hi alexpan13,
Thank you for taking the time to raise this. It’s a sharp observation and one that trips up a lot of people!
You’re absolutely correct that S3 live replication only applies to new objects written after the replication rule is configured. However, Option 1 is intentionally sequenced to account for this:
1. The new S3 bucket is created with replication rules already in place
2. The existing assets are then copied into the new primary bucket afterward
Because the assets arrive as new objects into a bucket where replication is already active, they get picked up and replicated to the other regions as expected; no existing objects are being directly replicated.
That said, your feedback is well taken. We’ll update the explanation to make the sequencing more explicit so it doesn’t cause confusion for other learners. We’ll also be adding a note about S3 Batch Replication, which is AWS’s native on-demand solution for replicating existing objects, and is worth knowing for the exam.
Thanks again for helping us improve the content. Keep the great questions coming!
Best regards,
Irene @ Tutorials Dojo
