Feature
Courseiva
This free Databricks-DE-Pro practice test mirrors the structure and difficulty of the real Databricks Certified Data Engineer Professional exam. Every question is written against the official 2026 exam blueprint published by Databricks, ensuring you practise exactly what the exam tests — not last year's objectives.
The Databricks-DE-Pro blueprint is divided into 10weighted domains. Questions on this page are distributed proportionally across each domain, so the mix you see here reflects the same weighting you'll face on exam day. High-weight domains like Data Ingestion and Acquisition and Data Governance contribute the most questions, meaning focused practice on these areas gives you the highest return on study time.
Databricks-DE-Pro Exam Blueprint — 10 Domains
Data Ingestion and Acquisition
Data Governance
Monitoring and Alerting
Debugging and Deploying
Data Security and Compliance
Data Sharing and Federation
Developing Code (Python/SQL)
Data Transformation, Cleansing, Quality
Data Modelling
Cost and Performance Optimization
21 numbered sets, 10 domain question banks, and targeted sessions — every page is a unique set of questions.
Each chapter page covers one topic in depth — theory, key concepts, and focused practice questions. Use these to close knowledge gaps before returning to full practice tests.
Getting the most from practice questions requires more than just clicking through answers. Here is the study method used by candidates who pass Databricks-DE-Pro on their first attempt:
Answer before revealing
Read each Databricks-DE-Pro question fully, eliminate obviously wrong choices, then commit to an answer before clicking to reveal. This active recall process is what builds lasting knowledge.
Read every explanation
Even when you answer correctly, read the full explanation. Knowing WHY the right answer is correct — and why the distractors are wrong — is what separates a 750 score from a 900 score.
Track weak domains
Note which Databricks-DE-Pro domains you get wrong most often. Then do a targeted 20-30 question session focused only on that domain until your accuracy improves.
Simulate exam pacing
The real Databricks-DE-Pro is 90 minutes long. Use timed sessions to build the concentration and pacing you will need on exam day.
Most candidates who pass Databricks-DE-Pro on their first attempt report doing between 400 and 800 practice questions over 4–8 weeks of preparation. With 267+ questions in the Courseiva bank, you have more than enough material to build that repetition without seeing the same question twice.
Answer each question to reveal the full explanation and correct answer. This starter set is drawn from all 10 exam domains in blueprint proportion. Use the session selector to start a longer focused practice run.

A data engineer is designing a solution to share a Delta table with an external partner organization. The partner uses a different Databricks account and must be able to read the table, but the data must not be copied outside the provider's cloud storage. The provider uses Unity Catalog and wants to minimize operational overhead while ensuring the partner sees only the shared table. Which Unity Catalog feature should the engineer use?

Answer all 20 questions to see your domain score breakdown
A structured study plan dramatically increases your chances of passing Databricks-DE-Pro on the first attempt. The most effective approach combines reading the official Databricks documentation or a study guide, watching video explanations for difficult concepts, and then reinforcing everything with daily practice questions.
We recommend the following weekly structure for Databricks-DE-Pro preparation:
Cover each Databricks-DE-Pro domain systematically. Read the exam objectives, watch explanatory content, and do 10–20 practice questions per domain to test understanding as you go.
Run full 50–60 question mixed sessions daily. Review every wrong answer in detail. Identify which domains are consistently scoring below 70% and revisit those study materials.
Do 100–120 question timed sessions to simulate real exam conditions. Aim for consistent scores above 80% before booking your exam date. A score above 80% in practice typically translates to a passing Databricks-DE-Pro score.
On exam day, the Databricks-DE-Pro tests your ability to apply knowledge to realistic scenarios — not just recall definitions. This is why reading explanations and understanding the reasoning behind every answer matters more than simply grinding question volume. Use the high-count sessions (100, 120) in the final weeks as your confidence benchmark.

Scaled scoring
The Databricks-DE-Pro exam uses a scaled scoring system — your raw score of correct answers is converted to a score out of 1000. A passing score of 700/1000 does not mean you need 70% of questions correct; the conversion accounts for question difficulty. Consistently scoring above 75–80% on practice tests puts you in a strong position to achieve 700/1000 on the real exam.

Every question is written against the official Databricks-DE-Pro exam blueprint published by Databricks. Our questions follow the same wording style, scenario complexity, and answer structure as the actual exam. They are original questions — not brain dumps — so you learn the underlying concepts and reasoning, not just memorised answers. Candidates who study with brain dumps often pass but have no transferable knowledge; Courseiva questions make you genuinely competent.
Most candidates who pass Databricks-DE-Pro on their first attempt do 30–60 questions per day. Use the Quick 10 session for daily warm-ups when you are short on time. On study days, run a 50 or 60-question session to build stamina. Reserve 100 and 120-question sessions for the final two weeks when you want to simulate real exam conditions and benchmark your readiness.
The Databricks-DE-Pro covers 10 domains: Data Ingestion and Acquisition, Data Governance, Monitoring and Alerting, Debugging and Deploying, Data Security and Compliance, Data Sharing and Federation, Developing Code (Python/SQL), Data Transformation, Cleansing, Quality, Data Modelling, Cost and Performance Optimization. Each domain carries a different weight, so allocate your study time accordingly. The highest-weighted domains — Data Ingestion and Acquisition and Data Governance — should receive the most attention.
Exam dumps are memorised question-and-answer lists taken from actual exam papers, often obtained illegally and shared without Databricks's authorisation. Using them violates your NDA and Databricks's certification agreement, and can result in certification revocation. Courseiva questions are original — AI-assisted, checked against the official exam objectives, and published under the editorial oversight of an engineer with 12+ years' experience. They test the same knowledge areas using new scenarios and wording. You learn the material, not just the answers.
