DVA-C02 Deployment Practice Question
A CloudFormation stack update fails and rolls back. Which two practices help diagnose and reduce future deployment risk?
⚠ Common exam trap
Test-takers frequently think disabling rollback is a valid troubleshooting step for production, but the exam emphasizes that rollback is a safety feature that should not be permanently disabled, as it prevents partial updates that could leave infrastructure in an inconsistent state.

Correct answer & explanation
✓
Review stack events and resource status reasons
Reviewing stack events and resource status reasons in CloudFormation provides detailed error messages for each resource that failed during the update. This allows you to pinpoint the exact cause of the failure, such as insufficient IAM permissions, a resource limit exceeded, or a dependency conflict. Analyzing these events is essential for diagnosing issues and preventing similar failures in future deployments.
