3 questions from the free diagnostic, with answers and explanations.
Which MLflow call assigns the alias "champion" to version 4 of a model registered in Unity Catalog?
Answer: A (MlflowClient().set_registered_model_alias(name, "champion", 4))
Aliases replace stages in the Unity Catalog registry; set_registered_model_alias points an alias at a version, and consumers load models:/name@champion.
Which class creates a feature table in Unity Catalog and writes features to it?
Answer: A (FeatureEngineeringClient)
databricks.feature_engineering.FeatureEngineeringClient works with feature tables in Unity Catalog (create_table, write_table, create_training_set). FeatureStoreClient is the legacy workspace API.
Which imputation is most robust for a numeric feature with extreme outliers?
Answer: A (Median)
The median isn't pulled by extreme values; the mean is. Mode suits categorical features.
