Adding to Vlad's answer, here are a few areas from the current exam guide (May 2026) that are easy to under-prepare from the courses alone:
- Governance and Security (15%): practise Unity Catalog access control with GRANT, REVOKE and DENY, managed vs external tables, and column masking and row-level security.
- Implementing CI/CD (10%): work with Databricks Git folders (branches, commits, pull requests) and deploy a bundle to dev, test and prod using variables and overrides. Watch the renames: Git folders were formerly Databricks Repos, and Declarative Automation Bundles were formerly Databricks Asset Bundles, so older material may use the old names.
- Troubleshooting, Monitoring and Optimization (10%): learn to spot data skew, shuffling and disk spilling from stage-level metrics in the Spark UI.
- Lakeflow Jobs (16%): retries, conditional tasks, and the three trigger types: scheduled, file arrival and table update.
On hands-on practice: the exam guide highly recommends six months of hands-on experience in Databricks, so treat the courses as the map and the workspace as where you actually learn each objective.
One more thing: the exam may include unscored items that aren't identified, so don't be thrown if a question looks slightly out of scope.
Good luck!
