This DOP-C02 practice question tests your understanding of monitoring and logging. 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 AWS CloudFormation to deploy infrastructure. The DevOps team wants to receive notifications when a stack creation fails due to a resource limit exceeded error. Which approach should be used?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Configure an SNS topic as a notification option in the CloudFormation stack, and subscribe an email endpoint.
Option B is correct because CloudFormation natively supports sending stack events (including creation failures) to an SNS topic. By configuring an SNS topic as a notification option in the stack creation request, the DevOps team can subscribe an email endpoint to receive real-time notifications when a resource limit exceeded error occurs, without needing additional services or custom logic.
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.
✗
Create an Amazon EventBridge rule that matches CloudFormation resource limit exceeded events and sends to SQS.
Why it's wrong here
This is possible but more complex; the simplest method is SNS directly.
✓
Configure an SNS topic as a notification option in the CloudFormation stack, and subscribe an email endpoint.
Why this is correct
CloudFormation can send stack events to SNS, which emails subscribers.
Related concept
Read the scenario before looking for a memorised answer.
✗
Use AWS Config to detect when a stack is in a failed state.
Why it's wrong here
Config does not monitor CloudFormation stacks.
✗
Enable CloudTrail and create a CloudWatch alarm on the CreateStack API call.
Why it's wrong here
CloudTrail logs the API call but does not send notifications.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often overcomplicate the solution by choosing EventBridge or CloudTrail-based monitoring, missing the fact that CloudFormation has a built-in, straightforward SNS notification feature specifically designed for real-time stack event alerts.
Detailed technical explanation
How to think about this question
CloudFormation's SNS notification option works by publishing stack events (e.g., CREATE_FAILED, DELETE_IN_PROGRESS) to the specified SNS topic as JSON messages, which include the 'ResourceStatusReason' field containing the exact error message (e.g., 'Resource limit exceeded'). This approach leverages CloudFormation's built-in event publishing mechanism, avoiding the need for custom event processing or polling. In a real-world scenario, the DevOps team could also subscribe an AWS Lambda function to the SNS topic to automate remediation, such as requesting a service quota increase.

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 cloud solutions architect for a retail company is evaluating services for a new workload. The correct answer here reflects best practice for the specific scenario described — not a general cloud recommendation. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Cloud exam questions reward reading the constraint carefully: the same technology can be right or wrong depending on the use case.
