Databricks doesn't issue a public exam code the way CompTIA or Microsoft do; some platforms use an internal identifier like "Databricks-Certified-Professional-Data-Engineer" for tracking purposes only.
60 multiple-choice and multiple-response questions, in 120 minutes, with a 70% passing score.
Not formally required, but strongly recommended — the Professional exam assumes Associate-level knowledge and goes significantly deeper.
Professional tests applied troubleshooting and optimization at production scale (streaming failures, checkpoint recovery, cost tuning), while Associate tests foundational ETL and platform knowledge.
2 years, with recertification requiring the then-current exam version.
