SOA-C02 Deployment, Provisioning, and Automation Practice Question
This SOA-C02 practice question tests your understanding of deployment, provisioning, and 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.
A company has multiple AWS accounts managed under AWS Organizations. The SysOps administrator needs to deploy a common AWS CloudFormation template to all accounts in a specific organizational unit (OU), ensuring consistent security group configurations across the organization. Which AWS service should the administrator use to perform this deployment?
StackSets are designed for deploying CloudFormation templates across multiple accounts and regions, and integrate with AWS Organizations to target OUs.
B
AWS CodePipeline with cross-account actions
Why wrong: This can work but requires building a custom pipeline and managing roles per account, adding operational overhead.
C
AWS Service Catalog portfolio
Why wrong: Service Catalog allows users to provision approved products but does not automatically deploy to all accounts in an OU.
D
AWS Systems Manager Automation
Why wrong: Automation is for runbooks on individual resources, not for deploying CloudFormation stacks at scale.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
AWS CloudFormation StackSets
AWS CloudFormation StackSets extends the functionality of CloudFormation by allowing you to deploy a common template across multiple accounts and regions from a single management account. In this scenario, the administrator can target the specific organizational unit (OU) within AWS Organizations, ensuring consistent security group configurations are applied to all member accounts without manual intervention.
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 AWS Service Catalog as a deployment mechanism for multi-account rollouts, but it is a governance tool for end-user provisioning, not an automated push deployment service like StackSets.
Detailed technical explanation
How to think about this question
CloudFormation StackSets uses a self-managed or service-managed permission model; with service-managed permissions, StackSets can automatically deploy to accounts in an OU as new accounts are added, leveraging AWS Organizations trusted access. The StackSet creates stack instances in target accounts, and any updates to the template are propagated via update operations, with the ability to set failure tolerances and concurrency limits to control the deployment pace. Under the hood, StackSets uses AWS CloudFormation's stack instance resource to manage the lifecycle of stacks across accounts, and it integrates with AWS CloudTrail for auditing all deployment actions.

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 healthcare organisation deploys an application with a public-facing web tier and a private database tier. The database subnet has no public IP and only accepts connections from the web tier's security group. Questions like this test whether you can design cloud network isolation using VNets/VPCs, subnets, and security group rules.
