The correct answer is to create an Amazon SNS topic with multiple subscribers and configure the CodePipeline manual approval action to use that SNS topic ARN. This works because the manual approval step in CodePipeline does not natively support a list of individual approvers or email addresses; instead, it relies entirely on SNS topics to broadcast the approval notification. Any subscriber of that SNS topic—whether an email address, Lambda function, or SMS endpoint—can then approve or reject the pipeline, satisfying the requirement that any one of multiple approvers can act. On the AWS Certified DevOps Engineer Professional DOP-C02 exam, this question tests your understanding of how CodePipeline integrates with SNS for decoupled approval workflows, and a common trap is assuming you can specify multiple IAM users or email addresses directly in the action configuration. Remember the key memory tip: "SNS is the bridge for multiple approvers—one topic, many subscribers, any can approve."
DOP-C02 SDLC Automation Practice Question
This DOP-C02 practice question tests your understanding of sdlc automation. 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.
An organization uses AWS CodePipeline to deploy a serverless application using AWS Lambda and Amazon API Gateway. The pipeline includes a manual approval action. The team wants to ensure that the approval email is sent to multiple approvers and that any one of them can approve or reject. How should the approval action be configured?
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 SNS topic with multiple subscribers, and configure the approval action to use that SNS topic ARN.
Option B is correct because the manual approval action in CodePipeline supports a list of SNS topic ARNs; any subscriber of that topic can approve or reject. Option A is wrong because the approval action does not have a 'multiple approvers' attribute; it uses SNS topics. Option C is wrong because you cannot specify multiple IAM users directly in the action. Option D is wrong because you cannot specify multiple email addresses directly in the action.
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.
✗
Specify multiple email addresses in the 'ApproverEmail' field of the approval action.
Why it's wrong here
The 'ApproverEmail' field accepts only a single email address; use SNS for multiple recipients.
✗
Set the 'Approvers' field in the approval action to a comma-separated list of IAM user ARNs.
Why it's wrong here
The approval action does not accept a list of IAM users; it uses SNS topics.
✗
Add multiple IAM users to the pipeline's service role.
Why it's wrong here
The service role defines permissions for the pipeline, not approval recipients.
✓
Create an Amazon SNS topic with multiple subscribers, and configure the approval action to use that SNS topic ARN.
Why this is correct
CodePipeline sends approval notifications to the SNS topic, and any subscriber can respond.

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 company's IT admin needs to give a contractor read-only access to production logs without sharing account credentials. Using role-based access control (RBAC) and temporary scoped permissions — not a permanent shared password — is the correct pattern. Questions like this test whether you can apply least-privilege access across cloud identity services.
