- A
Specify multiple email addresses in the 'ApproverEmail' field of the approval action.
Why wrong: The 'ApproverEmail' field accepts only a single email address; use SNS for multiple recipients.
- B
Set the 'Approvers' field in the approval action to a comma-separated list of IAM user ARNs.
Why wrong: The approval action does not accept a list of IAM users; it uses SNS topics.
- C
Add multiple IAM users to the pipeline's service role.
Why wrong: The service role defines permissions for the pipeline, not approval recipients.
- D
Create an Amazon SNS topic with multiple subscribers, and configure the approval action to use that SNS topic ARN.
CodePipeline sends approval notifications to the SNS topic, and any subscriber can respond.

DOP-C02 SDLC Automation Practice Question
This DOP-C02 practice question tests your understanding of sdlc automation. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. 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?

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 SNS topic with multiple subscribers, and configure the approval action to use that SNS topic ARN.
Option D is correct because AWS CodePipeline's manual approval action can be configured to send notifications through an Amazon SNS topic. By creating an SNS topic with multiple subscribers (e.g., email addresses), any one of the subscribers can receive the approval request and take action (approve or reject). This satisfies the requirement for multiple approvers where any single approver can act.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often assume the 'ApproverEmail' field can accept multiple addresses or that IAM-based approvers can be listed directly, but AWS CodePipeline relies on SNS for multi-approver scenarios, not direct email or IAM lists.
Detailed technical explanation
How to think about this question
Under the hood, CodePipeline's manual approval action publishes a message to the specified SNS topic when the action is reached. The SNS topic then delivers the notification to all subscribed endpoints (e.g., email, SMS, Lambda). The approval token is embedded in the notification link, allowing any subscriber to approve or reject. A subtle behavior is that if the SNS topic has multiple email subscribers, all receive the same approval link, and the first to click it completes the action; subsequent clicks will fail because the token is already consumed.
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 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.
