質問 1:A machine learning engineer has developed a random forest model using scikit-learn, logged the model using MLflow as random_forest_model, and stored its run ID in the run_id Python variable. They now want to deploy that model by performing batch inference on a Spark DataFrame spark_df.
Which of the following code blocks can they use to create a function called predict that they can use to complete the task?
A.
B.
C. It is not possible to deploy a scikit-learn model on a Spark DataFrame.
D.
E.
正解:A
質問 2:A machine learning engineer wants to view all of the active MLflow Model Registry Webhooks for a specific model.
They are using the following code block:

Which of the following changes does the machine learning engineer need to make to this code block so it will successfully accomplish the task?
A. Replace POST with GET in the call to http request
B. Replace list with webhooks in the endpoint URL
C. Replace POST with PUT in the call to http request
D. Replace list with view in the endpoint URL
E. There are no necessary changes
正解:B
質問 3:A machine learning engineer has deployed a model recommender using MLflow Model Serving. They now want to query the version of that model that is in the Production stage of the MLflow Model Registry.
Which of the following model URIs can be used to query the described model version?
A. The version number of the model version in Production is necessary to complete this task.
B. https://<databricks-instance>/model-serving/recommender/stage-production/invocations
C. https://<databricks-instance>/model/recommender/Production/invocations
D. https://<databricks-instance>/model-serving/recommender/Production/invocations
E. https://<databricks-instance>/model/recommender/stage-production/invocations
正解:A
質問 4:A data scientist has computed updated feature values for all primary key values stored in the Feature Store table features. In addition, feature values for some new primary key values have also been computed. The updated feature values are stored in the DataFrame features_df. They want to replace all data in features with the newly computed data.
Which of the following code blocks can they use to perform this task using the Feature Store Client fs?
A.
B.
C.
D.
E.
正解:E
質問 5:A data scientist would like to enable MLflow Autologging for all machine learning libraries used in a notebook. They want to ensure that MLflow Autologging is used no matter what version of the Databricks Runtime for Machine Learning is used to run the notebook and no matter what workspace-wide configurations are selected in the Admin Console.
Which of the following lines of code can they use to accomplish this task?
A. spark.conf.set("autologging", True)
B. It is not possible to automatically log MLflow runs.
C. mlflow.spark.autolog()
D. mlflow.sklearn.autolog()
E. mlflow.autolog()
正解:A
質問 6:A machine learning engineer wants to move their model version model_version for the MLflow Model Registry model model from the Staging stage to the Production stage using MLflow Client client. At the same time, they would like to archive any model versions that are already in the Production stage.
Which of the following code blocks can they use to accomplish the task?
A.
B.
C.
D.
正解:D
