Azure DevOps Engineer (AZ-400) pattern recognition

Deployment strategy selection and pipeline security integration are the main recurring patterns

Deployment strategy questions appear in multiple variations: blue/green, canary, and ring deployment each map to different risk tolerance and rollback requirements, and the scenario provides the signal to resolve the choice. Pipeline security integration questions test where scanning, secret management, and compliance gates belong in the pipeline sequence, and which Azure DevOps or GitHub Actions feature handles each concern. Artifact management and versioning questions form a third cluster: feed configuration, retention policy, and package promotion across environments. IaC governance questions test Bicep and Terraform deployment patterns within CI/CD pipelines, including how environment-specific overrides and compliance checking are structured. The structural decision in each cluster is consistent; only the scenario context changes.
