Adding a prep note since the voucher part is covered. If any of your study material is from before May, check it against the current exam guide. Databricks updated the Data Engineer Associate outline on 4 May 2026, and it now has separate sections for Working with Lakeflow Jobs (16%) and Implementing CI/CD (10%), plus a lot of Lakeflow Connect, COPY INTO and Auto Loader in Data Ingestion and Loading (21%).
The format is 45 scored questions in 90 minutes. Since you've done the courses, I'd spend the last few days doing things hands-on: an Auto Loader ingest with schema evolution, a multi-task job, and some Unity Catalog grants. Good luck!
