Yesterday's data and model synthesis now becomes "operations lifecycle" — deploy, orchestrate, monitor, secure. Domain 3 (Deployment/Orchestration, 22%) is inference options and ML pipeline automation. Domain 4 (Monitoring/Security, 24%) is post-deployment sensing and protection. Combined = 46% of exam.
Core message: Models don't end at deployment; you automate continuously (pipelines), monitor continuously (drift detection), and protect continuously (IAM/VPC/KMS). Request patterns shape inference; "what changed" drives monitoring; "least privilege + isolation + encryption" drives security.
