- A
View the CloudTrail event history for the delete-bucket event.
Viewing the CloudTrail event history for the delete-bucket event provides the source IP address and user agent because CloudTrail records management API calls, including DeleteBucket. This is the direct and correct method to obtain the required information.
- B
Check the S3 server access logs for the deleted bucket.
Why wrong: S3 server access logs record object-level operations (e.g., GET, PUT, DELETE on objects), not management actions like bucket deletion. Therefore, they would not contain the delete-bucket event.
- C
Use CloudWatch Logs to search for the event in the CloudTrail log group.
Why wrong: CloudWatch Logs can be used to search CloudTrail events if log delivery is configured, but this is an indirect method; the simplest approach is to view the event history in the CloudTrail console directly.
- D
Query AWS Config to find the configuration item for the bucket deletion.
Why wrong: AWS Config provides configuration history of AWS resources, but it does not record API call details such as source IP or user agent for the DeleteBucket action. It tracks resource changes, not the API call metadata.
DOP-C02 Incident and Event Response Practice Question
This DOP-C02 practice question tests your understanding of incident and event response. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. 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 AWS CloudTrail to audit API activity. During an incident investigation, they find that a user with the IAM policy 'AdministratorAccess' deleted an S3 bucket. The security team wants to know the source IP address and user agent used for the delete operation. Which action should the team take to obtain this information?
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
View the CloudTrail event history for the delete-bucket event.
The correct answer is A. CloudTrail event history captures all management events, including DeleteBucket, and records the source IP address and user agent for each API call. By viewing the event history for the specific delete-bucket event, the security team can directly retrieve the required metadata without needing additional log sources or configurations. Option B is incorrect because S3 server access logs log object-level operations, not management events like bucket deletion. Option C is not the most direct method; CloudWatch Logs can be used if CloudTrail is configured to send events to a log group, but the simplest way is from CloudTrail event history directly. Option D is incorrect because AWS Config tracks resource configuration changes, not API call details like source IP.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
View the CloudTrail event history for the delete-bucket event.
Why this is correct
Viewing the CloudTrail event history for the delete-bucket event provides the source IP address and user agent because CloudTrail records management API calls, including DeleteBucket. This is the direct and correct method to obtain the required information.

Check the S3 server access logs for the deleted bucket.
Why it's wrong here
S3 server access logs record object-level operations (e.g., GET, PUT, DELETE on objects), not management actions like bucket deletion. Therefore, they would not contain the delete-bucket event.
- ✗
Use CloudWatch Logs to search for the event in the CloudTrail log group.
Why it's wrong here
CloudWatch Logs can be used to search CloudTrail events if log delivery is configured, but this is an indirect method; the simplest approach is to view the event history in the CloudTrail console directly.
- ✗

Why it's wrong here
AWS Config provides configuration history of AWS resources, but it does not record API call details such as source IP or user agent for the DeleteBucket action. It tracks resource changes, not the API call metadata.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates confuse S3 server access logs (which log object-level operations) with CloudTrail management events, leading them to incorrectly choose option B for a bucket deletion that is a management API call.
Detailed technical explanation
How to think about this question
CloudTrail event history retains the last 90 days of management events by default, and each event record includes fields like sourceIPAddress, userAgent, and userIdentity. For S3 management operations (e.g., DeleteBucket), the event is logged as a management event, not a data event, so it appears in the event history without requiring additional data event logging configuration.
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.
TExam Day Tips
- 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 |
