ML Model Lifecycle And Operations

This domain covers the operational half of the ML lifecycle on Azure Machine Learning: deploying models, scoring at scale, monitoring for drift, and retraining. Questions are scenario-based, asking where a setting lives (deployment vs. endpoint), which config property to change, or which metric signals a need to act.

What this domain covers

What to know about ML Model Lifecycle And Operations

Be able to deploy a model to a managed online endpoint, configure a parallel batch scoring job, set up monitoring and retraining triggers, and secure training data at rest. The single most important thing: know which object owns each setting, especially deployment-level compute versus endpoint-level configuration.

Choosing instance_type and instance_count on a managed online deployment, not the endpoint itself

Tuning ParallelRunConfig properties such as mini_batch_size and max_concurrency_per_instance for batch scoring

Selecting monitoring signals like data drift and model performance metrics to trigger retraining

Configuring encryption at rest using Microsoft-managed keys or customer-managed keys in Key Vault

Watch out for

Common ML Model Lifecycle And Operations exam traps

  • ▸Setting instance type on the managed online endpoint instead of on the individual deployment, which is where compute is defined
  • ▸Confusing data drift with prediction drift, or monitoring only infrastructure metrics instead of model quality signals
  • ▸Assuming Blob Storage is encrypted by default with customer keys; you must configure a customer-managed key explicitly
