Potential flaw in DOP-C02 practice exam answer

[alexpan13]

“Utilize AWS CloudFormation StackSets to provision a new S3 bucket with versioning enabled in multiple regions. Create several S3 replication rules on the new S3 bucket in the primary region to replicate all its contents to the other regions. Copy the important assets from the existing S3 bucket to the new S3 bucket in the primary region.”

This answer implies that replication can copy EXISTING objects. This tripped me up and may be poorly worded as S3 Replication only copies NEW objects after the rule has been applied.

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,
