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 is using AWS CloudFormation to deploy infrastructure. The DevOps team wants to receive notifications when a stack creation fails. Which services can be used together to send an email notification on stack failure? (Choose TWO.)
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Amazon Simple Notification Service (SNS)
Amazon SNS (Option C) is correct because it can send email notifications to subscribers when a CloudFormation stack creation fails. AWS CloudFormation (Option D) is correct because it can directly publish failure events to an SNS topic via the 'NotificationARNs' parameter in stack creation, enabling automated email alerts without additional services.
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.
✗
AWS Lambda
Why it's wrong here
Incorrect. Lambda can be used but is not required.
✗
Amazon Simple Queue Service (SQS)
Why it's wrong here
Incorrect. SQS is for message queuing, not direct email.
✓

✗
Amazon CloudWatch
Why it's wrong here
Incorrect. CloudWatch is not directly integrated with CloudFormation for notifications.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates might think CloudWatch (Option E) can send emails directly, but CloudWatch only publishes to SNS or other targets; it cannot natively deliver email notifications without SNS.
Detailed technical explanation
How to think about this question
CloudFormation's 'NotificationARNs' parameter allows you to specify an SNS topic ARN where stack events (including failures) are published automatically. SNS then handles fan-out to multiple protocols (email, SMS, HTTP) via subscriptions. This integration is synchronous and event-driven, ensuring immediate notification without polling or custom code. A common real-world scenario is using SNS to notify DevOps teams via email while also triggering Lambda for automated rollback actions.

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 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.
