Q54. A machine learning engineer is migrating a machine learning pipeline to use Data bricks Machine Learning. The pipeline needs to automatically refresh its model each time it runs.
They are using the following code block as part of their solution:

Assuming that this is the first time that the model is being run, which statement describes the impact of the registered_model_name=model_name parameter?

It registers the new version of the existing model_name model in the MLflow Model Registry.

It registers a new model called model_name in the MLflow Model Registry.

It avoids the need to specify the model name in the subsequent required call to mflow.register_model.

It identifies the name of the logged model in the MLflow Experiment.

Q55. Which of the following MLflow Model Registry use cases requires the use of an HTTP Webhook?

Starting a testing job when a new model is registered

Updating data in a source table for a Databricks SQL dashboard when a model version transitions to the Production stage

Sending an email alert when an automated testing Job fails

None of these use cases require the use of an HTTP Webhook

Sending a message to a Slack channel when a model version transitions stages

Q56. Which of the following Databricks-managed MLflow capabilities is a centralized model store?

Models

Model Registry

Model Serving

Q57. A Machine Learning Engineer has a real-time fraud detection model deployed that approves or blocks millions of transactions daily. They need to deploy a new version of the model with improved detection accuracy to this high-traffic, business-critical application. Because any model downtime could result in lost revenue or customer dissatisfaction, the engineer must ensure zero downtime and minimal disruption for end users. Leadership also requires that any rollback to the previous version be immediate if issues are detected with the new model in production. Which deployment strategy meets these requirements?

Use a canary deployment by initially routing a small percentage of user traffic to the new model version, monitoring results, and gradually increasing exposure until all traffic uses the new version if no problems are detected.

Replace the current production model with the new version during a scheduled maintenance window, notify affected users of potential brief disruptions, and prepare to reroute requests to a backup if failures occur after deployment.

Use a blue-green deployment for the new model, maintaining two separate production environments (one “blue,” one “green”) and switching user traffic to the new version only after confirming it is healthy, enabling instant rollback if needed.

Deploy the new model in parallel with the old version, monitor both for a set period, and then notify all stakeholders to manually switch over to the new version at a coordinated time.

Q58. A data scientist has developed a scikit-learn model sklearn_model and they want to log the model using MLflow.
They write the following incomplete code block:

Which lines of code can be used to fill in the blank so the code block can successfully complete the task?

mlflow.spark.track_model(sklearn_model, “model”)

mlflow.sklearn.log_model(sklearn_model, “model”)

All of these reasons

JS requires a manual threshold or cutoff determinations

JS is not robust when working with large datasets

None of these reasons

Q60. A Machine Learning Engineer has a production AI model that predicts fraudulent transactions in real time. This model is integrated into critical business workflows and any downtime could result in significant financial loss and regulatory penalties. The engineer needs to deploy a new, improved version of the model to production to replace the existing model. The bank’s fairness policy requires that all transactions be exposed to the same model at any given time. Additionally, the deployment must meet the following requirements:
– Zero downtime: The fraud detection service must remain continuously
available to users and downstream systems.
– Immediate rollback: If the new model causes issues, you must be able
to revert to the previous version instantly.
Which deployment strategy meets these requirements?

Canary

Rolling

Shadow

Blue-Green

Replace POST with PUT in the call to http request

Q63. A machine learning engineer and data scientist are working together to convert a batch deployment to an always-on streaming deployment. The machine learning engineer has expressed that rigorous data tests must be put in place as a part of their conversion to account for potential changes in data formats. Which of the following describes why these types of data type tests and checks are particularly important for streaming deployments?

Because the streaming deployment is always on, all types of data must be handled without producing an error

All of these statements

Because the streaming deployment is always on, there is no practitioner to debug poor model performance

Because the streaming deployment is always on, there is a need to confirm that the deployment can autoscale

None of these statements

Q64. A Data Scientist is developing a model training pipeline on Databricks and needs to track custom performance metrics during training. They want to log a custom evaluation score (team_score), a single hyperparameter, and a confusion matrix plot as part of their MLflow experiment.

The current integration test runs the complete workflow but takes four hours to execute due to large dataset processing and extensive model training. They need to select an approach that will be the most effective for optimizing integration test execution while maintaining test reliability. The approach should also be based on MLOps best practices. Which approach will do this?

Run integration tests only in the production environment using full datasets to ensure complete accuracy of the testing process.
