Greetings @AyubkhanNazar ,
Youโre absolutely right to double-check this. Unity Catalog is still in scope for the current Databricks Certified Data Engineer Associate (DEA) exam, under the Data Governance & Quality domain, which makes up 11% of the exam weighting.
What changed in the training
Itโs completely normal that the updated learning path shows less Unity Catalog inside the core data engineering course itself. UC prep has been pulled out and is now surfaced as a dedicated self-paced module called โData Management and Governance with Unity Catalog.โ Youโll see it listed on the official DEA certification page as related training, and itโs also called out on our internal certification resources page. Net effect: less duplication in the core course, not less coverage on the exam.
Exactly what to study for Unity Catalog on the DEA
Based on the latest exam guide, you should be comfortable with the following UC topics:
โข The difference between managed and external tables.
โข How permissions work in Unity Catalog, including granting access to users and groups (for example, GRANT SELECT on schemas, tables, or views), plus general awareness of key UC roles.
โข Where audit logs live and how theyโre used at a basic, conceptual level.
โข Using lineage features in Unity Catalog.
โข Delta Sharing with UC: how sharing works, Databricks-to-Databricks vs external systems, high-level advantages and limitations, and cost considerations across clouds.
โข Lakehouse Federation: when and why youโd use it for external sources, framed at a conceptual/use-case level.
How to prepare efficiently
If you want to be smart and time-efficient about this:
โข Start with the official exam guide and re-check it about two weeks before your test date. Itโs always the source of truth for scope changes.
โข Take the Academy module โData Management and Governance with Unity Catalogโ as part of the DEA related training lineup.
โข Do a light hands-on refresher in a workspace:
โ Create a managed table and an external table and compare behavior.
โ Practice GRANT and REVOKE on a schema and a table.
โ View lineage for a dataset.
โ Walk through setting up a simple Delta Share to an external recipient, aligned to the examโs conceptual expectations.
