- A
Use CloudFormation stack tags that propagate to all resources in the stack.
Stack tags are automatically applied to all resources that support tagging.
- B
Create an AWS Config rule to automatically tag resources after creation.
Why wrong: Config rules can auto-remediate tags but do not prevent creation.
- C
Use an AWS Organizations service control policy (SCP) to deny creation of resources that are not tagged.
SCPs can enforce tagging on resource creation.
- D
Add an IAM policy that denies cloudformation:CreateStack unless the template includes the required tags.
Why wrong: IAM policies cannot inspect the contents of the template.
- E
Enable AWS CloudTrail to log all API calls and monitor for untagged resources.
Why wrong: CloudTrail logs actions but does not enforce tagging.
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 to deploy infrastructure. They want to enforce mandatory tags on all resources created by CloudFormation. 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 CloudFormation stack tags that propagate to all resources in the stack.
Option A is correct because CloudFormation stack tags propagate to all resources that support tagging within the stack. When you specify tags at the stack level, CloudFormation automatically applies them to each resource it creates, ensuring mandatory tags are enforced without additional configuration.
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 reactive detection (AWS Config) with proactive prevention (SCPs or stack tags), or mistakenly believe IAM policies can parse template content to enforce tagging rules.
Detailed technical explanation
How to think about this question
CloudFormation stack tags propagate via the `aws:cloudformation:stack-name` and `aws:cloudformation:stack-id` system tags, and any user-defined tags are applied to resources during creation using the `TagSpecification` parameter in the underlying API calls. SCPs can deny resource creation if required tags are missing by using the `aws:RequestTag` condition key, which evaluates tags specified in the API request before the resource is created, providing a preventive control at the organization level.
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.
