Actual Dumps for Databricks Databricks Machine Learning Professional Exam 2026

Question No: 1

MultipleChoice

A machine learning engineer is migrating a machine learning pipeline to use Databricks Machine Learning. They have programmatically identified the best run from an MLflow Experiment and stored its URI in the model_uri variable and its Run ID in the run_id variable. They have also determined that the model was logged with the name "model". Now, the machine learning engineer wants to register that model in the MLflow Model Registry with the name "best_model".

Which of the following lines of code can they use to register the model to the MLflow Model Registry?

Options

Amlflow.register_model(model_uri, 'best_model')

Bmlflow.register_model(run_id, 'best_model')

Cmlflow.register_model(f'runs:/{run_id}/best_model', 'model')

Dmlflow.register_model(model_uri, 'model')

Emlflow.register_model(f'runs:/{run_id}/model')

Question No: 2

MultipleChoice

Which of the following is a benefit of logging a model signature with an MLflow model?

Options

AThe model will have a unique identifier in the MLflow experiment

BThe schema of input data can be validated when serving models

CThe model can be deployed using real-time serving tools

DThe model will be secured by the user that developed it

EThe schema of input data will be converted to match the signature

Question No: 3

MultipleChoice

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

Options

Amlflow.spark.track_model(sklearn_model, 'model')

Bmlflow.sklearn.log_model(sklearn_model, 'model')

Cmlflow.spark.log_model(sklearn_model, 'model')

Dmlflow.sklearn.load_model('model')

Emlflow.sklearn.track_model(sklearn_model, 'model')

Question No: 4

MultipleChoice

A machine learning engineer is attempting to create a webhook that will trigger a Databricks Job job_id when a model version for model model transitions into any MLflow Model Registry stage.

They have the following incomplete code block:

Which option best lines of code can be used to fill in the blank so that the code block accomplishes the task?

Options

A'MODEL_VERSION_CREATED'

B'MODEL_VERSION_TRANSITIONED_TO_PRODUCTION'

C'MODEL_VERSION_TRANSITIONED_TO_STAGING'

D'MODEL_VERSION_TRANSITIONED_STAGE'

E'MODEL_VERSION_TRANSITIONED_TO_STAGING', 'MODEL_VERSION_TRANSITIONED_TO_PRODUCTION'

Question No: 5

MultipleChoice

Which of the following is a simple statistic to monitor for categorical feature drift?

Options

AMode

BNone of these

CMode, number of unique values, and percentage of missing values

DPercentage of missing values

ENumber of unique values

Question No: 6

MultipleChoice

Which of the following is a probable response to identifying drift in a machine learning application?

Options

ANone of these responses

BRetraining and deploying a model on more recent data

CAll of these responses

DRebuilding the machine learning application with a new label variable

ESunsetting the machine learning application

Question No: 7

MultipleChoice

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 option best describes why these types of data type tests and checks are particularly important for streaming deployments?

Options

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

BAll of these statements

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

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

ENone of these statements
