Databricks Certified Machine Learning Professional Databricks-Machine-Learning-Professional Prüfungsfragen mit Lösungen (Q191-Q196):

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

Antwort: C

192. Frage
A Data Scientist has been performing hyperparameter tuning using Ray Tune with grid search.
After team discussions, they decide to switch to Bayesian optimization to more efficiently explore the parameter space.
Their current code is:

How can they implement this change?

Antwort: B

Begründung:
Bayesian optimization in Ray Tune requires defining a continuous or discrete search space (such as tune.randint) and explicitly configuring a Bayesian search algorithm. Using tune.randint defines a probabilistic parameter domain, and setting search_alg to BayesOptSearch enables Bayesian optimization to efficiently explore the space based on past trial results, rather than exhaustively enumerating all values as in grid search.

193. Frage
A machine learning engineer has created a webhook with the following code block:

Which of the following code blocks will trigger this webhook to run the associate job?

Antwort: D

194. Frage
A machine learning engineer has developed a model and registered it using the FeatureStoreClient fs. The model has model URI model_uri. The engineer now needs to perform batch inference on customer-level Spark DataFrame spark_df, but it is missing a few of the static features that were used when training the model. The customer_id column is the primary key of spark_df and the training set used when training and logging the model.
Which of the following code blocks can be used to compute predictions for spark_df when the missing feature values can be found in the Feature Store by searching for features by customer_id?

A. fs.score_batch(model_uri, df)
B. fs.score_model(model_uri, spark_df)
C. fs.score_batch(model_uri, spark_df)
D. df = fs.get_missing_features(spark_df, model_uri)
fs.score_batch(model_uri, df)
df = fs.get_missing_features(spark_df)
E. df = fs.get_missing_features(spark_df, model_uri)
fs.score_model(model_uri, df)

Antwort: C

195. Frage
A Machine Learning Engineer has deployed a fraud detection model that processes 10,000 transactions per hour. The model was trained on data from Q1 2024, but it's now Q4 2024. The ML team notices three concerning trends: (1) the model's precision has dropped from 92% to
78% over the past month, (2) the average transaction amount in recent data has increased from
$150 to $220 and (3) the relationship between transaction frequency and fraud likelihood has weakened significantly due to new payment methods being introduced. The engineer needs to implement a monitoring solution that can detect the root cause of the performance degradation, identify why the precision dropped, and be able to do this at the scale needed. Which monitoring pipeline component will do this?

A. Model Performance Monitoring Pipeline because it directly tracks precision metrics and can alert when thresholds are breached.
B. Model Health Monitoring Pipeline because it ensures the infrastructure can handle the 10,000 transactions per hour load.
C. Drift Detection Pipeline because it can identify both the data drift (transaction amount changes) and concept drift (weakened relationship between features and target).
D. Logging and Monitoring Pipeline because it captures all prediction requests and can identify patterns in the fraud predictions.

Antwort: C

Begründung:
A drift detection pipeline is designed to diagnose the root causes of model performance degradation at scale. It can detect data drift, such as changes in the distribution of transaction amounts, and concept drift, where the relationship between input features and the fraud label changes due to new payment methods. This directly explains why precision dropped and provides actionable insight beyond simply observing metric degradation.
