Databricks Certified Machine Learning Professional Databricks-Machine-Learning-Professional Prüfungsfragen mit Lösungen (Q11-Q16):

11. Frage
A machine learning engineer wants to deploy a model for real-time serving using MLflow Model Serving. For the model, the machine learning engineer currently has one model version in each of the stages in the MLflow Model Registry. The engineer wants to know which model versions can be queried once Model Serving is enabled for the model. Which of the following lists all of the MLflow Model Registry stages whose model versions are automatically deployed with Model Serving?

A. Production
B. None, Staging, Production, Archived
C. Staging, Production, Archived
D. None, Staging, Production
E. Staging, Production

Antwort: E

12. Frage
A data scientist has developed and logged a scikit-learn random forest model model, and then they ended their Spark session and terminated their cluster. After starting a new cluster, they want to review the feature_importances_ of the original model object.
Which of the following lines of code can be used to restore the model object so that feature_importances_ is available?

A. mlflow.sklearn.load_model(model_uri)
B. client.list_artifacts(run_id)["feature-importances.csv"]
C. mlflow.load_model(model_uri)
D. This can only be viewed in the MLflow Experiments UI
E. client.pyfunc.load_model(model_uri)

Antwort: C

13. Frage
A machine learning engineer is using the following code block as part of a batch deployment pipeline:

Which of the following changes needs to be made so this code block will work when the inference table is a stream source?

A. Replace predict with a stream-friendly prediction function
B. Replace schema(schema) with option("maxFilesPerTriqqer", 1}
C. Replace "inference" with the path to the location of the Delta table
D. Replace formatfdelta") with format("stream")
E. Replace spark.read with spark.readStream

Antwort: B

14. Frage
A data scientist has developed a scikit-learn random forest model model, but they have not yet logged model with MLflow. They want to obtain the input schema and the output schema of the model so they can document what type of data is expected as input. Which of the following MLflow operations can be used to perform this task?

A. mlflow.models.Model.get_input_schema
B. There is no way to obtain the input schema and the output schema of an unlogged model.
C. mlflow.models.signature.infer_signature
D. mlflow.models.schema.infer_schema
E. mlflow.models.Model.signature

Antwort: C

15. Frage
A Data Scientist is building a propensity model for an e-commerce start-up. The company maintains 7GB of historical data and receives about 5MB of new transaction data daily. The goal is to generate daily purchase predictions for all users by 7:00 AM each morning. As the start-up is in its early stages, the data scientist must prioritize a highly cost-efficient approach. Which approach should the Data Scientist take?

A. Use a multi-node compute and leverage distributed frameworks like SparkML to train the model.
The model can then be scheduled as a nightly batch job that runs on a multi-node compute.
B. Use a single-node compute to build a model with libraries like scikit-learn. The model can then be deployed as an always-on REST API so that users can query the API to get the predictions whenever they want.
C. Use a single-node memory compute to build a model with libraries like scikit-learn. The model can then be scheduled as a nightly batch job that runs on a single-node compute.
D. Use a single-node compute to build a model with libraries like scikit-learn. The model can then be integrated into an always-on streaming pipeline, to ensure immediate processing of incoming data in order to meet the SLA.

Antwort: C

Begründung:
With only 7GB of historical data and a small daily increment (about 5MB), a single-node memory- optimized cluster can comfortably train and score using scikit-learn without the overhead and cost of distributed compute. Scheduling a nightly batch job is the most cost-efficient way to meet a fixed daily SLA (7:00 AM) because the compute can be started only for the job run and then terminated, avoiding the expense of always-on serving or streaming infrastructure.
