- A
Restore the bucket from AWS CloudTrail event history
Why wrong: Option A is incorrect because CloudTrail logs are used for auditing and cannot restore a deleted bucket.
- B
Contact AWS Support to restore the bucket from a backup if versioning was enabled
Why wrong: Option B is incorrect because AWS Support cannot restore a deleted S3 bucket. Versioning protects object versions but does not prevent deletion of the bucket itself.
- C
Recreate the bucket with the same name and restore objects from a previous backup
Option C is correct because the only way to recover from a deleted bucket is to recreate it and restore objects from a backup. (Note: bucket name uniqueness may require waiting or using a different name.)
- D
Use the AWS S3 console to undo the deletion
Why wrong: Option D is incorrect because the S3 console does not provide an undo delete option for buckets.
DOP-C02 Incident and Event Response Practice Question
This DOP-C02 practice question tests your understanding of incident and event response. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. 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 uses Amazon S3 to store critical data. An incident occurs where an S3 bucket is accidentally deleted. The DevOps engineer needs to recover the bucket and its objects. What should the engineer do?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
Recreate the bucket with the same name and restore objects from a previous backup
Option C is correct because if the bucket was deleted, the only way to recover the data is to recreate the bucket (note: the bucket name may not be immediately available, but you can create a new bucket with a different name) and restore objects from a previous backup, assuming backups exist. Option B is incorrect because AWS Support cannot restore a deleted S3 bucket; versioning helps recover individual object versions but does not prevent bucket deletion. Option A is incorrect because CloudTrail logs API calls but cannot restore buckets. Option D is incorrect because the S3 console does not have an undo feature for bucket deletion.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
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
How to think about this question
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.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
- Use explanations to understand the rule behind the answer.
TExam Day Tips
- Underline the problem statement mentally.
- Watch for words such as best, first, most likely and least administrative effort.
- Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
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.
Quick reference
AWS S3 Storage Class Comparison
| Storage Class | Min Duration | Retrieval | Use Case |
|---|---|---|---|
| S3 Standard | None | Immediate | Frequently accessed data |
| S3 Standard-IA | 30 days | Immediate | Infrequent access, rapid retrieval |
| S3 One Zone-IA | 30 days | Immediate | Non-critical infrequent data |
| S3 Intelligent-Tiering | None | Immediate–hours | Unknown or changing access patterns |
| S3 Glacier Instant | 90 days | Milliseconds | Archive with instant retrieval |
| S3 Glacier Flexible | 90 days | Minutes–hours | Archive, flexible retrieval |
| S3 Glacier Deep Archive | 180 days | Hours | Long-term compliance archive |
