- A
Create an IAM role in the new account that trusts the StackSet.
Why wrong: The IAM role is created automatically with service-managed permissions.
- B
Create a new StackSet that includes the new account.
Why wrong: There is no need to create a new StackSet; you can update the existing one.
- C
Manually create a stack instance for the new account in the StackSet.
Why wrong: With service-managed permissions, stack instances are automatically created for accounts in the organization.
- D
Add the new account to the AWS Organization.
Adding the account to the organization allows StackSets to deploy to it automatically.

DOP-C02 Configuration Management and IaC Practice Question
This DOP-C02 practice question tests your understanding of configuration management and iac. 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.
A company uses AWS CloudFormation StackSets to deploy a common security baseline across multiple AWS accounts. They have a new account that needs to be added to the StackSet. The StackSet is configured with self-service permissions and uses a service-managed IAM role. What must be done to include the new account?
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
✓
Add the new account to the AWS Organization.
When a StackSet uses service-managed permissions, it relies on AWS Organizations to manage accounts. To include a new account, you must add it to the AWS Organization; the StackSet will automatically deploy stack instances to that account based on the specified organizational units (OUs) or accounts. This is because service-managed permissions use a service-linked role created and managed by CloudFormation, not a manually created IAM role in the target account.
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 self-service permissions (which require manual IAM role creation and stack instance management) with service-managed permissions (which rely on AWS Organizations for automatic account and stack instance management), leading them to choose Option A or C incorrectly.
Detailed technical explanation
How to think about this question
Service-managed StackSets use AWS CloudFormation StackSets with AWS Organizations to automatically deploy stacks across accounts in specified OUs. The service-linked role (AWSServiceRoleForCloudFormationStackSetsOrgAdmin) is created in the management account, and CloudFormation uses it to create and manage stack instances in target accounts without requiring manual role setup. This integration ensures that when a new account is added to an OU targeted by the StackSet, the stack is automatically deployed, reducing operational overhead and ensuring consistent baseline compliance.
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.
