Start with the rules of the game
Before you write any Spark you need to know what you're preparing for, the same way you'd read the requirements before building a pipeline. This level covers how the Databricks Certified Data Engineer Associate exam works and how to use this course alongside it.
Two honest notes first:
- This course is independent of Databricks. Databricks doesn't endorse it, and no course can promise you a pass. What we can do is cover every objective in proportion to how much it's worth.
- The official exam guide belongs to Databricks, and we don't reproduce it here. It's free on the certification page (databricks.com → Learn → Certification → Data Engineer Associate). Download it today. You'll use it as your checklist.

The exam may include unscored items. Databricks uses them to gather statistics for future exams. They aren't marked and don't affect your score, and Databricks adds extra time to cover them. So you might see more than 45 questions on screen, and you won't know which ones count. Treat every question as scored.
One detail affects how you study: data manipulation code in the exam is shown in SQL where possible, and in Python otherwise. Get fluent at reading Spark SQL first. Then make sure you can read PySpark for the tasks SQL can't express.
The seven sections and their weights
Here are the weights turned into rough question counts. Real exam forms will vary a little.
# Section weights from Databricks' certification page
weights = {
"Databricks Intelligence Platform": 0.06,
"Data Ingestion and Loading": 0.21,
"Data Transformation and Modeling": 0.22,
"Working with Lakeflow Jobs": 0.16,
"Implementing CI/CD": 0.10,
"Troubleshooting, Monitoring, and Optimization": 0.10,
"Governance and Security": 0.15,
}
for section, w in weights.items():
print(f"{section:<48} {w:>4.0%} ~{45 * w:.1f} questions")
Databricks Intelligence Platform 6% ~2.7 questions
Data Ingestion and Loading 21% ~9.5 questions
Data Transformation and Modeling 22% ~9.9 questions
Working with Lakeflow Jobs 16% ~7.2 questions
Implementing CI/CD 10% ~4.5 questions
Troubleshooting, Monitoring, and Optimization 10% ~4.5 questions
Governance and Security 15% ~6.8 questions
Ingestion plus transformation make up 43% of the exam, so that's where most of your study hours should go. This course is weighted the same way.
Gotcha: older blog posts and practice tests often show a five-section layout (Development and Ingestion 30%, Data Processing & Transformations 31%, and so on). That layout is from an earlier exam version. If the weights you're reading aren't 6/21/22/16/10/10/15, the material is out of date.
Your time budget
90 minutes ÷ 45 questions = 2 minutes per question. A practical pacing plan:
Checkpoint Target
------------- -----------------------------------
30 min elapsed ~15 questions done
60 min elapsed ~30 questions done
80 min elapsed all answered; use the rest on flagged items
If a question takes more than about 3 minutes, pick your best guess, flag it and move on. Easy marks later in the exam count just as much.
Reading the questions like an engineer
Two patterns come up again and again in Databricks exams.
1. "Best answer" scenarios. The stem describes a situation, for example "a team needs to incrementally ingest new files with minimal operational overhead". Several options might technically work. Only one fits every constraint. Underline the qualifiers in your head: incrementally, minimal overhead, least privilege, most cost-effective. Those words decide the answer.
2. Product-contrast distractors. Wrong options are often real Databricks features that solve a nearby problem: two ingestion tools, two kinds of table, an old product name next to a new one. You'll learn these contrasts in later levels. For now, expect that a wrong option will often be a real feature used in the wrong place, not a made-up one.
Best practice: Databricks renames products often. Lakeflow Declarative Pipelines was formerly Delta Live Tables, for example. Learn the current names, because that's the wording the exam uses.
Prerequisites, training and experience
There are no formal prerequisites. Databricks highly recommends related training, and it recommends hands-on experience doing the data engineering tasks the exam guide lists. The current guide suggests course attendance and roughly six months of hands-on Databricks work. Check its recommended training list rather than relying on anyone's summary, including this one. If you don't have workplace experience, run every code example in this course in a workspace yourself.
Getting ready: the official sequence
Databricks lays out these steps:
- Review the Data Engineer Associate Exam Guide.
- Take the related training listed in the guide.
- Use the AI Prep Guide to prepare.
- Register for the exam.
- Review the technical requirements for online proctoring and run a system check.
- Review the exam guide again to find any gaps.
- Study to fill those gaps.
- Take your exam.
To register, log in to Databricks' exam delivery platform or create an account there. That's also where you choose your exam language. If English isn't your strongest language, consider Japanese, Brazilian Portuguese or Korean.
Gotcha: if you're taking the exam online, run the system check days ahead, not minutes before. Webcam, browser or corporate-firewall problems are much easier to fix in advance.
Recertification
The certification is valid for two years. To stay certified you must pass the current version of the exam, which won't be the version you passed. Put a calendar reminder about 3 months before expiry, download the latest exam guide, and compare its sections with what you know.
What the exam asks about this
The exam doesn't test its own logistics. Getting them right shapes everything else, though: you'll pace at 2 minutes per question, read SQL first, put most of your study time into the 21% and 22% sections, and expect real-but-wrong product names as distractors.
Key takeaways
- 45 scored multiple-choice questions, 90 minutes, $200, no test aids, online or at a test centre; unscored items may appear.
- Weights: 6 / 21 / 22 / 16 / 10 / 10 / 15. Ingestion plus transformation is 43%.
- Code is shown in SQL where possible, Python otherwise.
- Available in English, Japanese, Brazilian Portuguese and Korean. You choose when you register.
- No formal prerequisites; training and hands-on experience are recommended.
- Valid 2 years; recertify by passing the current exam version.
- The exam guide is Databricks' own and free. Use it as your checklist. This course is independent and promises no pass.
