Who should take the Databricks DEA?
Databricks DEA is an associate-level, role-based certification. There are no formal prerequisites, but Databricks recommends hands-on experience — the questions are scenarios, not definitions.
You already build on Databricks
You run real workloads and want the credential that matches the job you're already doing — and the salary conversations that come with it.
You're moving into a cloud role
The exam blueprint doubles as a job description. Studying it task statement by task statement is the fastest way to find and close your skill gaps.
You hold a foundational cert
The natural next step on the same platform: deeper services, scenario-based questions, and a credential employers screen for by name.
What’s on the Databricks DEA exam
Every lesson, question, and mock is weighted to match these official domains.
Databricks Intelligence Platform
The Data Intelligence Platform itself: its architecture, Delta Lake and Unity Catalog, and choosing the right compute for each workload by characteristics, limits and cost.
Data Ingestion and Loading
Getting data in: batch, streaming and incremental patterns, COPY INTO, Auto Loader, Lakeflow Connect connectors, JDBC/ODBC and REST clients, choosing between ingestion methods, and semi-structured data.
Data Transformation and Modeling
Bronze to silver to gold with PySpark and SQL: cleaning, joins and unions, column and row manipulation, deduplication and aggregation, basic Spark tuning, gold-layer objects in Unity Catalog, and data quality checks.
Working with Lakeflow Jobs
Orchestrating pipelines with Lakeflow Jobs: control flow (retries, branching, looping), task types and dependencies in the DAG, schedules and trigger types, and choosing time-based versus data-driven triggers.
Implementing CI/CD
Shipping data code safely: Git Folders branching, commits and pull requests in the workspace, Declarative Automation Bundles (formerly Databricks Asset Bundles) with per-environment variables and overrides, and the Databricks CLI in CI/CD.
Troubleshooting, Monitoring, and Optimization
Keeping pipelines healthy and fast: run-history trends and job health in the Lakeflow Jobs UI, skew, shuffle and spill in the Spark UI, Liquid Clustering and predictive optimization, and diagnosing startup, library and memory failures.
Governance and Security
Unity Catalog governance: managed versus external tables, GRANT/REVOKE/DENY across the securable hierarchy, column masking and row-level security, and ABAC policies for central filtering and masking.
