Databricks-ML-Assoc ML Workflows Practice Question
A data scientist is building a training pipeline where raw event data lands in a Delta table. They need to transform the data, train a model, and register it to the Databricks Model Registry. The pipeline must run daily on a schedule and send an email alert if training fails. Which Databricks construct should they use to orchestrate the entire workflow?
⚠ Common exam trap
The trap here is assuming MLflow Projects provide scheduling and alerting, when they only package code and must be orchestrated by a separate scheduler.

Correct answer & explanation
✓
A Databricks Job with multiple tasks that include a notebook task for data transformation, a notebook task for training, and a task that registers the model, with email notifications configured on the Job.
Databricks Jobs with multiple tasks are the native way to orchestrate multi-step ML workflows. You can define task dependencies so transformation runs before training, and training before registration. Job-level notifications send email alerts on failure, and the built-in scheduler handles the daily cadence. This satisfies all requirements without external tooling.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
A Databricks Job with multiple tasks that include a notebook task for data transformation, a notebook task for training, and a task that registers the model, with email notifications configured on the Job.
Why this is correct
A Databricks Job supports multiple tasks with dependencies, so transformation, training, and registration can be sequenced in one workflow. Job-level email notifications on failure satisfy the alerting requirement, and the Job scheduler runs it daily. This is the native Databricks orchestration construct for multi-step ML workflows.
- ✗
An MLflow Project that defines the transformation, training, and registration steps in its MLproject file and is run with mlflow run on a schedule.
Why it's wrong here
MLflow Projects package code and dependencies for reproducibility, but they do not provide a native scheduler or failure-alerting mechanism. The question requires daily scheduling and email alerts on failure, which an MLflow Project alone cannot deliver. It might be used as a component inside a Job, but it is not the orchestration construct.
- ✗
A Delta Live Tables pipeline that performs transformations and automatically trains and registers the model as part of the pipeline.
Why it's wrong here
Delta Live Tables pipelines are designed for declarative data engineering transformations and data quality, not for general ML training and model registration steps. While you can run ML logic inside, DLT does not natively orchestrate model training and registration as pipeline stages, nor does it provide the required email alert on training failure.
- ✗
A Databricks SQL dashboard that queries the raw Delta table, calls an external training service via a webhook, and emails the results.
Why it's wrong here
Databricks SQL dashboards are for analytics and visualization, not orchestration of training pipelines. They do not execute Python training code or register models to the Model Registry. A webhook-based approach would be fragile and is not a supported pattern for end-to-end ML workflow orchestration with failure alerts.
