SAP-C02 Continuous Improvement for Existing Solutions Practice Question

The operations team wants to automatically roll back to the previous working configuration if errors exceed a threshold. Which solution provides the fastest rollback?
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
✓
Implement AWS CodeDeploy with automatic rollback triggered by CloudWatch alarms.
AWS CodeDeploy supports automatic rollback based on CloudWatch alarm thresholds, providing the fastest rollback by reverting to the previous working deployment revision automatically. Option A is incorrect because manually restoring AMI snapshots is slow and error-prone. Option B is incorrect because AWS Elastic Beanstalk with rolling updates and health checks can perform rollbacks, but it is slower and less granular than CodeDeploy’s immediate alarm-based rollback. Option C is incorrect because AWS CloudFormation stack policies prevent updates and do not facilitate automatic rollback of the application deployment.
