What the exam tests
Exam domains and official weightings
From the official Google Cloud exam guides. Put your study time where the weight is.
The percentage is the exam weighting. The bar is our verified questions in that domain against the best covered one, so a short bar is where the 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.
Every Data Engineer objective, with practice questions mapped to each one
What the exam actually asks you to do
Multiple choice and multiple select, in Google's own words. No labs, no console access, and nothing to configure during the exam.

Data Engineer practice exams
Full-length forms, 40 questions each, apportioned to the published domain weightings so every one stands alone as a representative sample. The questions in a numbered form are fixed, so two attempts on the same form are comparable.
Sit any of them under exam conditions, with the clock running and nothing revealed until you submit, or in study mode, with the full explanation after every answer. You choose when you start. 5 questions from across every form are free, with no account and no card.

Where Data Engineer fits
An honest study plan
1. Read the official objectives first
Download the official objectives from Google Cloud and skim every line. The exam can only test what’s listed there, it’s the contract.
2. Weight your study toward Ingesting and processing the data and Designing data processing systems
Together the top two domains are 47% of the exam. Practise them until your accuracy is consistently above 80%.
3. Drill weak domains, then sit a numbered practice exam
Use Domain Drill on your weakest areas, then sit a full-length form under exam conditions: 40 questions in 120 minutes, scored against the published pass mark. Book the real exam when you are consistently clearing that, not before.

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.
