SAP-C02 Design for New Solutions Practice Question
Network Topology
Refer to the exhibit. A CloudFormation stack has been deployed with the VPCId and SubnetIds outputs. A developer wants to use these outputs as parameters in another CloudFormation stack. Which AWS service can be used to pass these values to the new stack?
⚠ Common exam trap
It's easy for candidates to confuse Parameter Store (a general-purpose parameter store) with CloudFormation's native cross-stack reference feature, overlooking that the question explicitly asks for passing outputs between CloudFormation stacks, which is directly solved by `Export` and `ImportValue`.

Correct answer & explanation
✓
CloudFormation cross-stack references using Export and ImportValue
CloudFormation cross-stack references using the `Export` output attribute and the `Fn::ImportValue` intrinsic function allow you to pass output values from one stack as parameters to another stack within the same AWS account and region. This is the native, recommended mechanism for sharing stack outputs without introducing external services or additional complexity.

AWS Secrets Manager
Why it's wrong here
Secrets Manager is for secrets, not outputs.
- ✗
AWS Systems Manager Parameter Store
Why it's wrong here
Not the native way; cross-stack references are better.

CloudFormation cross-stack references using Export and ImportValue
Why this is correct
Exports allow passing outputs to other stacks.
