SAP-C02 Continuous Improvement for Existing Solutions Practice Question
A company uses AWS CloudFormation to deploy infrastructure. They have a stack that creates an Amazon RDS for MySQL database. The stack creation fails with the error 'The following resource(s) failed to create: [DBInstance]'. The solutions architect needs to troubleshoot the issue. Which approach should be taken first?
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
✓
Review the CloudFormation stack events in the AWS Management Console.
When a CloudFormation stack creation fails, the stack events provide detailed status reasons for each resource, including the specific error message for the DBInstance. This is the first step to diagnose the failure. Option B is incorrect because while RDS events may show database-level issues, the failure occurred during stack creation and CloudFormation events are more direct. Option C is incorrect because deleting and redeploying without understanding the cause is inefficient. Option D is incorrect because CloudTrail logs API calls but does not provide the detailed resource failure reasons that CloudFormation events do.
