Google Professional-Cloud-DevOps-Engineer Question Answer
Your company uses a CI/CD pipeline with Cloud Build and Artifact Registry to deploy container images to Google Kubernetes Engine (GKE).

During the rollback, you noticed many old and unused container images accumulating in Artifact Registry. You need to improve rollout and rollback management and clean up the old container images. What should you do?
