Quick Answer
The answer is to delete the delete marker. When versioning is enabled on an S3 bucket, a delete operation does not actually remove the underlying object; instead, it places a delete marker on the current version, effectively hiding the object from list results. To recover a deleted object, you must remove that delete marker, which restores the original object version and makes it visible again. On the AWS Certified Developer Associate DVA-C02 exam, this concept tests your understanding of S3 versioning mechanics and the distinction between permanent deletion and soft deletion via markers. A common trap is assuming you need to restore from Glacier or copy from another bucket, but the key is that the object data still exists underneath the marker. Remember: with versioning, a delete is just a marker—remove the marker, recover the object.
This DVA-C02 practice question tests your understanding of security. Match the stated requirement to the specific cloud service, access model, or configuration option — many options are valid in isolation but not for this scenario. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
A company has an S3 bucket with versioning enabled. A developer accidentally deleted an object. What must be done to recover it?
Copy the object from another bucket
Why wrong: There is no other copy.
Restore the object from Glacier Deep Archive
Why wrong: The object is not archived; it has a delete marker.
Delete the delete marker
Removing the delete marker restores the object.
Enable versioning on the bucket
Why wrong: Versioning is already enabled.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
Delete the delete marker
With versioning enabled, when an object is deleted, a delete marker is added. To recover, the delete marker must be removed. Option A (restore from Glacier) is not relevant. Option B (enable versioning) is already enabled. Option D (copy from another bucket) is unnecessary.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
For each option: why learners choose it and why it is or isn't the right answer here.
Copy the object from another bucket
Why it's wrong here
There is no other copy.
Restore the object from Glacier Deep Archive
Why it's wrong here
The object is not archived; it has a delete marker.
Delete the delete marker
Why this is correct
Removing the delete marker restores the object.

Common exam traps
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.
Detailed technical explanation
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
A media company stores terabytes of video archives that are accessed once a year for audit purposes. Moving these objects to a cold storage tier (Azure Archive, S3 Glacier, or Google Nearline) costs a fraction of hot storage. Questions like this test whether you understand storage tiers, access frequency tradeoffs, and retrieval latency requirements.
