The correct answers are that AWS CloudFormation StackSets can deploy stacks across multiple accounts, and that StackSets can be integrated with AWS Organizations for centralized management. This is because StackSets extend CloudFormation’s capabilities by allowing you to define a single template and then deploy it as a stack instance across specified accounts and regions, using either self-managed permissions or service-managed permissions tied to an organization. On the AWS Certified DevOps Engineer Professional DOP-C02 exam, this concept tests your understanding of multi-account governance and automation, often appearing in scenario-based questions where you must choose the correct tool for cross-account resource provisioning. A common trap is assuming StackSets natively support nested stacks across accounts—they do not—or that CloudFormation automatically creates accounts, which is handled by AWS Organizations. Remember the mnemonic: “StackSets stack across sets of accounts, but nested stacks stay in their own nests.”
DOP-C02 Configuration Management and IaC Practice Question
This DOP-C02 practice question tests your understanding of configuration management and iac. 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.
Which TWO are correct about using AWS CloudFormation to manage infrastructure across multiple AWS accounts? (Select TWO.)
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
You can use AWS Organizations to centrally manage accounts and use StackSets with trusted access.
Option C is correct because StackSets allow deploying stacks across accounts. Option D is correct because you can use AWS Organizations to manage accounts and StackSets can be integrated. Option A is wrong because StackSets do not support nested stacks across accounts natively. Option B is wrong because CloudFormation does not automatically create accounts. Option E is wrong because CloudFormation templates cannot reference resources across accounts without explicit parameters.
Key principle: NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✓
You can use AWS Organizations to centrally manage accounts and use StackSets with trusted access.
Why this is correct
Organizations integration enables StackSets across accounts.
Related concept
Static NAT maps one inside address to one outside address.
✗
CloudFormation can automatically create new AWS accounts using a template.
Why it's wrong here
CloudFormation cannot create accounts.
✗
Nested stacks can be used to deploy resources in different accounts from a single template.
Why it's wrong here
Nested stacks are within the same account.
✓
AWS CloudFormation StackSets can deploy stacks across multiple accounts.
Why this is correct
StackSets are designed for multi-account deployments.
Related concept
Static NAT maps one inside address to one outside address.
✗
You can use cross-stack references to share resources between accounts.
Why it's wrong here
Cross-stack references work within the same account.
Common exam traps
Common exam trap: NAT rules depend on direction and matching traffic
NAT is not only about the public address. The inside/outside interface roles and the ACL or rule that matches traffic are just as important.
Detailed technical explanation
How to think about this question
NAT questions usually test address translation, overload/PAT behaviour, static mappings and whether the right traffic is being translated. Read the interface direction and address terms carefully.
KKey Concepts to Remember
Static NAT maps one inside address to one outside address.
PAT allows many inside hosts to share one public address using ports.
Inside local and inside global describe the private and translated addresses.
NAT ACLs identify traffic for translation, not always security filtering.
TExam Day Tips
→Identify inside and outside interfaces first.
→Check whether the scenario needs static NAT, dynamic NAT or PAT.
→Do not confuse NAT matching ACLs with normal packet-filtering intent.
Key takeaway
NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.
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.
What to study next
Got this wrong? Here's your next step.
Review the four NAT address types (inside local, inside global, outside local, outside global), PAT port overload, and static vs dynamic NAT use cases. Then practise related DOP-C02 NAT questions on configuration and troubleshooting.
