SAP-C02 Continuous Improvement for Existing Solutions Practice Question
A company uses AWS CloudFormation to deploy a multi-tier application. The stack fails to update due to a resource conflict. The operations team needs to identify the resource causing the failure and modify the template to allow the update. Which approach is MOST effective?
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
✓
Create a Change Set for the stack to preview the changes and identify the conflict.
A Change Set allows you to preview the changes that will be made during a stack update, including any potential errors or resource conflicts, before executing the update. This helps identify the specific resource causing the failure. Option B is wrong because the Events tab shows past events but does not provide a preview of planned changes or conflicts. Option C is wrong because StackSets are used for deploying stacks across multiple accounts and regions, not for troubleshooting a single stack update. Option D is wrong because drift detection compares the current stack resources with the template to identify manual changes, not update conflicts.
