- A
Use AWS CodePipeline with a manual approval stage before the CloudFormation deployment action.
CodePipeline supports manual approval gates.
- B
Use CloudFormation StackSets with approval tokens.
Why wrong: StackSets do not provide approval tokens.
- C
Use CloudFormation Change Sets and require a separate user to execute them.
Why wrong: Change Sets allow review but do not enforce approval from a different user.
- D
Use AWS Service Catalog to manage CloudFormation templates and require approval for product launches.
Why wrong: Service Catalog is for provisioning, not updating existing stacks.
- E
Implement a custom AWS Lambda function that checks a ticketing system before allowing the update to proceed.
Lambda can integrate with external approval systems.
Question 160 of 1,750
Implementing Change Management Approval for CloudFormation Updates
This DOP-C02 practice question tests your understanding of configuration management and iac. 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 company uses AWS CloudFormation to deploy infrastructure. They want to implement a change management process that requires approval before any stack update is executed. Which TWO approaches can achieve this? (Choose TWO.)
Answer choices
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
✓
Use AWS CodePipeline with a manual approval stage before the CloudFormation deployment action.
Option A is correct because AWS CodePipeline can include a manual approval action that pauses the pipeline until an authorized user approves the change, after which the CloudFormation deployment action executes the stack update. This enforces a formal approval gate before any infrastructure change is applied.
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 confuse Change Sets (which allow review but not approval enforcement) with a true approval workflow, or they incorrectly assume StackSets or Service Catalog can be repurposed for stack update approvals.
Detailed technical explanation
How to think about this question
In AWS CodePipeline, the manual approval stage uses an SNS notification to alert approvers, and the pipeline remains in a 'waiting' state until the approval is granted or rejected via the AWS console or API. For CloudFormation Change Sets, the separation of create and execute actions provides a review opportunity but no built-in approval mechanism—any IAM principal with `cloudformation:ExecuteChangeSet` permission can bypass the review. A custom Lambda function could integrate with external ticketing systems (e.g., Jira, ServiceNow) by using the AWS SDK to check ticket status before allowing the update, but this requires custom development and maintenance.
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 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.
