The answer is Amazon CloudWatch Events (now part of Amazon EventBridge) to trigger an SNS notification. This is correct because CloudWatch Events can monitor CodePipeline state changes—specifically, when a stage execution enters a "waiting" status at the manual approval step—and route that event to an SNS topic, which then delivers the email to subscribers. CodePipeline itself has no built-in email capability, and while SES can send emails, the standard AWS pattern for pipeline notifications is to use CloudWatch Events as the event bus and SNS as the notification channel. On the AWS Certified Developer Associate DVA-C02 exam, this question tests your understanding of event-driven automation and service integration, often appearing as a scenario where you must choose the correct combination of services. A common trap is selecting SES because it sends email, but the exam expects you to recognize that CloudWatch Events is the trigger, not the delivery mechanism. Memory tip: think "Pipeline Pauses → Events Watches → SNS Notifies" to remember the chain.
DVA-C02 Troubleshooting and Optimization Practice Question
This DVA-C02 practice question tests your understanding of troubleshooting and optimization. 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 developer is using AWS CodePipeline to automate a multi-stage pipeline. The pipeline includes a manual approval step before deploying to production. The developer wants to receive an email notification when the pipeline reaches the approval step. Which service should the developer use?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Use Amazon CloudWatch Events to detect the pipeline state change and trigger an SNS notification
Option B is correct because CloudWatch Events (EventBridge) can detect the pipeline state change (e.g., stage execution state changed to 'waiting') and trigger an SNS topic to send email. Option A is wrong because CodePipeline does not directly send email notifications. Option C is wrong because CloudWatch Logs is for logging, not notifications. Option D is wrong because SES is for sending emails directly, but CloudWatch Events with SNS is the standard approach.
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.
✗
Configure CodePipeline to send an email using the 'Email' action
Why it's wrong here
CodePipeline does not have a built-in email action.
✗
Use Amazon CloudWatch Logs to monitor the pipeline logs and trigger an alarm
Why it's wrong here
CloudWatch Logs is not designed for real-time pipeline state monitoring.
✗
Use Amazon Simple Email Service (SES) to send an email from the pipeline
Why it's wrong here
SES can send emails, but it requires a Lambda function or custom integration; EventBridge+SNS is simpler.
✓
Use Amazon CloudWatch Events to detect the pipeline state change and trigger an SNS notification
Why this is correct
CloudWatch Events can monitor pipeline stage transitions and publish to an SNS topic.

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.

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 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.
