Databricks Certified Machine Learning Professional Sample Questions (Q35-Q40):

NEW QUESTION # 35
Why is Apache Spark useful for machine learning training?

A. Data visualization
B. Distributed data processing
C. Web serving
D. GPU rendering

Answer: B

Explanation:
Spark processes large distributed datasets efficiently.

NEW QUESTION # 36
A Machine Learning Engineer uses Lakehouse Monitoring to track their credit scoring model's performance. The existing profile metrics table contains three aggregate metrics:
- adefault_risk_score
- payment_history_score
- credit_utilization_score
They need to:
1. Create a composite risk rating that combines these three scores using weights of 0.5, 0.3, and 0.2 respectively.
2. Monitor drift of this composite score against an established baseline.
Which approach should be used to implement both requirements within Lakehouse Monitoring?

A. Create an aggregate metric for composite_risk_rating and configure a separate drift metric to monitor changes.
B. Use a scheduled notebook to calculate the composite score and manually insert both the score and drift values into the profile metrics table.
C. Create two separate aggregate metrics: one for the composite score calculation and another for drift detection.
D. Create a derived metric for the composite_risk_rating calculation and create a drift metric on this derived metric.

Answer: D

Explanation:
Lakehouse Monitoring supports derived metrics that are computed from existing profile metrics using custom expressions. By defining a derived metric for the composite_risk_rating using the specified weights, the composite score becomes a first-class metric in the monitoring framework.
A drift metric can then be directly configured on this derived metric to compare current values against the baseline, fulfilling both the composite calculation and drift monitoring requirements in a native, governed way.

NEW QUESTION # 37
Which of the following is a simple, low-cost method of monitoring numeric feature drift?

A. Summary statistics trends
B. Kolmogorov-Smirnov (KS) test
C. Jensen-Shannon test
D. Chi-squared test
E. None of these can be used to monitor feature drift

Answer: A

NEW QUESTION # 38
A Machine Learning Engineer needs to deploy a custom model using Databricks Model Serving.
The model requires an external tokenizer file (for example, a vocabulary or pre-trained tokenizer) to function correctly. They need to ensure this tokenizer file is included with the model so it is available during model serving. How should they package this tokenizer file as part of the model deployment?

A. Use the code_paths parameter in mlflow.pyfunc.log_model() to include the tokenizer file, assuming it's part of the custom Python logic needed by the model.
B. Use the artifacts parameter in mlflow.pyfunc.log_model() to package the tokenizer file, referencing its path in Volumes.
C. Access the tokenizer file directly from Volumes at model inference time, which requires pre- provisioning access to the Volume for every model serving endpoint.
D. Include tokenizer file as part of the model's software dependencies by adding it to the conda_env specification.

Answer: B

Explanation:
The artifacts parameter in mlflow.pyfunc.log_model is designed for packaging non-code assets required at inference time, such as tokenizer files. By logging the tokenizer as a model artifact and referencing its path, MLflow ensures the file is versioned with the model and automatically made available to Databricks Model Serving during inference.

NEW QUESTION # 39
A Machine Learning Engineer needs to digitize millions of historical documents spanning 200+ years with vastly different handwriting styles, fonts, languages, document conditions, and paper types. To do this, the engineer wants to train thousands of specialized OCR models to extract text. The number of documents vary significantly. They need an efficient approach for this parallel model training task. Which approach suits their needs?

A. Use Scikit-learn's ML library within a Pandas UDF to parallelize training across data partitions.
Use groupby.applyInPandas.
B. Use Ray map_in_batches to allocate resources based on the various sizes of models and data volumes.
C. Use Spark MLlib with custom Spark UDFs to distribute across partitions.
D. Use Spark for data preprocessing and orchestrate parallel model training jobs through Databricks workflows.

Answer: B

Explanation:
Ray's map_in_batches API is designed for large-scale, heterogeneous parallel workloads where tasks vary significantly in data size, model complexity, and resource requirements. It enables dynamic resource allocation and efficient scheduling across many specialized OCR training jobs, making it well suited for training thousands of models with uneven document volumes and computational needs.
