- A
Using the 'Ref' function with the parameter name
Why wrong: Ref returns the parameter name as a string, not its value.
- B
Using the 'Fn::ParamStore' intrinsic function
Why wrong: There is no intrinsic function 'Fn::ParamStore'.
- C
Using 'Fn::GetAtt' on the Parameter Store resource
Why wrong: Fn::GetAtt is used to get attributes of a resource created in the template, not to fetch from Parameter Store.
- D
Using the 'resolve:ssm' dynamic reference
Dynamic references allow you to retrieve values from Parameter Store or Secrets Manager.

DOP-C02 Configuration Management and IaC Practice Question
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 team uses CloudFormation to deploy a multi-container Docker environment on Amazon ECS. They need to pass environment variables to the containers from Parameter Store. How should they reference these values in the CloudFormation template?
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
✓
Using the 'resolve:ssm' dynamic reference
Option D is correct because CloudFormation supports dynamic references using the 'resolve:ssm' prefix to retrieve values from AWS Systems Manager Parameter Store at stack creation or update time. This allows environment variables in an ECS task definition to be populated directly from Parameter Store without hardcoding secrets or using custom Lambda-backed custom resources.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Using the 'Ref' function with the parameter name
Why it's wrong here
Ref returns the parameter name as a string, not its value.
- ✗
Using the 'Fn::ParamStore' intrinsic function
Why it's wrong here
There is no intrinsic function 'Fn::ParamStore'.
- ✗
Using 'Fn::GetAtt' on the Parameter Store resource
Why it's wrong here
Fn::GetAtt is used to get attributes of a resource created in the template, not to fetch from Parameter Store.
- ✓
Using the 'resolve:ssm' dynamic reference
Why this is correct
Dynamic references allow you to retrieve values from Parameter Store or Secrets Manager.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates may confuse CloudFormation's 'Ref' function with the ability to fetch SSM parameter values, or invent a non-existent function like 'Fn::ParamStore', instead of recognizing the dedicated 'resolve:ssm' dynamic reference syntax.
Detailed technical explanation
How to think about this question
Dynamic references in CloudFormation use the syntax '{{resolve:ssm:parameter-name}}' or '{{resolve:ssm-secure:parameter-name}}' for secure strings, which are resolved during stack operations. This approach avoids exposing sensitive values in the template or outputs, and the resolved values are passed directly to ECS container definitions as environment variables. Under the hood, CloudFormation calls the SSM GetParameter API with the appropriate permissions, ensuring the parameter exists and the caller has access.
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.
