This DVA-C02 practice question tests your understanding of deployment. 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 company deploys a microservices application using AWS CloudFormation. Each microservice is deployed as a separate stack. The developer wants to pass the output values (e.g., API endpoint URLs) from one stack to another. Which CloudFormation feature should be used?
Custom resources with Lambda
Why wrong: Overly complex for simple value sharing.
Stack outputs
Why wrong: Outputs are only available within the same stack unless exported.
Nested stacks
Why wrong: Nested stacks treat one stack as parent of others, not independent.
Cross-stack references using Export and ImportValue
Exports allow values to be imported by other stacks.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
Cross-stack references using Export and ImportValue
Option C is correct because cross-stack references using Fn::ImportValue and Export allow you to pass outputs from one stack to another. Option A is wrong because nested stacks are for hierarchical dependencies, not independent stacks. Option B is wrong because Outputs are not automatically available to other stacks. Option D is wrong because custom resources are for custom logic, not simple value passing.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.
Trap categories for this question
Command / output trap
Outputs are only available within the same stack unless exported.
Detailed technical explanation
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
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.
