Flashcard Practice Databricks Certified Machine Learning Associate Multiple Choice

A company sends a scoring DataFrame that includes `account_creation_date` with test values, expecting the scorer to use the values from the feature table instead. The predictions use the supplied column. What explains this behavior?

Choose the Best Answer

Supplying an expected feature column can override lookup for that feature value. Databricks converts all date features into strings before scoring. The feature table primary key was removed during model logging. The scoring DataFrame cannot include any columns other than lookup keys.
