- A
Use CloudWatch Logs Insights to run a query every hour and send results via email.
Why wrong: This is not real-time and requires manual setup for email.
- B
Set up an AWS Config rule to detect when an access key is created.
Why wrong: Config evaluates resource compliance, not API events.
- C
Configure S3 event notifications on the CloudTrail bucket to trigger a Lambda function.
Why wrong: S3 events are for object creation, not for specific API calls.
- D
Create an Amazon EventBridge rule that matches the 'CreateAccessKey' event and targets an SNS topic.
EventBridge can filter CloudTrail events and send alerts via SNS.

DOP-C02 Monitoring and Logging Practice Question
This DOP-C02 practice question tests your understanding of monitoring and logging. 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 uses AWS CloudTrail to log API activity. The security team needs to be alerted when an IAM user creates a new access key. How can this be achieved with minimal overhead?
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
✓
Create an Amazon EventBridge rule that matches the 'CreateAccessKey' event and targets an SNS topic.
D is correct because Amazon EventBridge can capture real-time CloudTrail API events, such as 'CreateAccessKey', and route them directly to an SNS topic for immediate notification. This approach requires no polling, no custom code, and minimal overhead, as EventBridge handles event matching and delivery natively.
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.

Set up an AWS Config rule to detect when an access key is created.
Why it's wrong here
Config evaluates resource compliance, not API events.
- ✗
Configure S3 event notifications on the CloudTrail bucket to trigger a Lambda function.
Why it's wrong here
S3 events are for object creation, not for specific API calls.
- ✓

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse AWS Config (which evaluates resource state) with EventBridge (which evaluates API events), leading them to choose Option B, but Config cannot react to API calls in real-time and is not designed for event-driven alerting.
Detailed technical explanation
How to think about this question
EventBridge uses a default event bus that receives all CloudTrail API calls as events; you can create a rule with an event pattern matching the 'eventName' field set to 'CreateAccessKey' and the 'userIdentity.type' as 'IAMUser'. The rule can then target an SNS topic, which sends notifications via email, SMS, or other endpoints in near real-time, typically within seconds of the API call. This pattern is serverless, requires no infrastructure management, and scales automatically.
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.
