Databricks Data Engineer Professional: 5 Practice Tests

Are you ready to sit the Databricks Certified Data Engineer Professional exam? This course answers that question with 295 exam-style questions across five full-length practice tests, each one 59 questions long, exactly the number of scored questions on the real exam.Every question is built on the official exam guide dated 3 July 2026 and its ten sections, using the weightings Databricks publishes: Developing Code for Data Processing using Python and SQL, Data Ingestion and Acquisition, Data Transformation, Cleansing and Quality, Data Sharing and Federation, Monitoring and Alerting, Cost and Performance Optimization, Ensuring Data Security and Compliance, Data Governance, Debugging and Deploying, and Data Modeling. Because every test uses the same distribution, your per-domain score report is comparable across attempts.That currency matters more for this exam than for most. In September 2025 the exam was restructured from six sections to ten, and the July 2026 guide added the published weightings and moved to 59 scored questions. Material written for the old structure drills Databricks SQL warehousing and skips Unity Catalog managed tables, Lakehouse Federation, deletion vectors, liquid clustering, Change Data Feed, row filters and column masks, and Declarative Automation Bundles. It also uses retired product names. This course uses the terminology of the current guide: Lakeflow Spark Declarative Pipelines, Lakeflow Jobs, AUTO CDC, Declarative Automation Bundles and Databricks Git folders.The five tests get harder in a deliberate order. Test 1 is groundwork, one concept per question. Test 2 puts you in short practical situations. Test 3 is the hard one: two answers are defensible and a single constraint decides. Test 4 goes down to parameter names, SQL syntax and CLI commands. Test 5 is a full simulation with the longest scenarios and the real 120-minute clock.Every answer option carries its own feedback saying why it is right or wrong and what the wrong option actually is, plus an overall explanation with a link to the official documentation. Tests 1 to 4 require 80 percent to pass and test 5 requires 85 percent, above the real exam, because practising at home is milder than sitting in a test centre.This is a question bank with explanations, not a video course. It will find your weak sections and explain the answers.
