SAP-C02 Continuous Improvement for Existing Solutions Practice Question
A company uses AWS CodePipeline to deploy a microservices application to Amazon ECS. Recently, a deployment failed because the new task definition referenced an ECR image that did not exist. The team wants to prevent this type of failure in the future. Which action should be taken?
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
✓
Add a validation step in CodePipeline to run a task definition dry-run.
Adding a validation step in CodePipeline that runs a task definition dry-run can verify the referenced ECR image exists before deployment, preventing failures. Option A is wrong because ECR scan on push only checks for vulnerabilities, not image existence. Option B is wrong because ECR lifecycle policies manage image retention, not validation. Option D is wrong because CloudTrail logs API calls but does not prevent deployment failures.
