Data Engineer practice exams
2 full-length forms, 40 questions each, apportioned to the published domain weightings.
An engineer opens the Parallel processing chart for a Streaming Engine job to see why extra workers changed nothing. What does that chart approximate?
The answer
How many keys each stage has in use
Checked against
cloud.google.com, checked August 2026The Parallel processing chart shows the approximate number of keys in use for data processing for each stage.
What the exam tests
Exam domains and official weightings
The percentage is the exam weighting; the bar is how many verified questions we hold there, so a short bar is where our bank is thin.
- Designing data processing systems22%18 verified
- Ingesting and processing the data25%20 verified
- Storing the data20%16 verified
- Preparing and using data for analysis15%12 verified
- Maintaining and automating data workloads18%14 verified
Where to focus: Ingesting and processing is the largest section at 25 percent, and pairing it with designing data processing systems puts pipeline work at 47 percent of the exam. The two smallest sections, preparing data for analysis at 15 and maintaining workloads at 18, are where most people underprepare because they read as operational rather than architectural.

Frequently asked questions
Do I need Associate Cloud Engineer first?
No. Google states no prerequisite for any professional certification, and plenty of people go straight to Data Engineer from a data background. It is listed as a prerequisite here because the Associate covers the projects, IAM and networking groundwork this exam assumes you already have, and skipping it usually means learning that groundwork anyway under exam pressure.
How much of this is BigQuery?
More than any other single service, but less than people expect. Storing the data is 20 percent of the exam and the warehouse sub-objective is one part of that. Ingesting and processing is the largest section at 25 percent, and that is Dataflow, Pub/Sub and Dataproc territory.
Is it a written exam or hands-on?
Written. Forty to fifty multiple choice and multiple select questions in two hours, with no lab component. The questions are scenario-heavy, so knowing which service fits a described constraint matters more than recalling syntax.
How long does it stay valid?
Two years, which is shorter than the three years foundational and associate certifications get. Renewal means passing the exam again.
