Databricks-DE-Pro › Developing Code (Python/SQL)

Developing Code (Python/SQL) Practice Questions

This domain covers writing PySpark and Spark SQL on Databricks: reading cloud files with the DataFrameReader, schema inference and explicit schemas, Delta Lake reads/writes, Delta Live Tables expectations, and tuning shuffle, broadcast, and memory behavior on clusters. Questions present realistic code or job symptoms and ask you to pick the correct API, config, or DLT expectation behavior.
