Updated October 2026: six new practice exams, 300 questions, written for the current exam guide.

These practice exams are written by Dan Sullivan, author of the Official Google Cloud Certified Professional Data Engineer Study Guide (Wiley). I rewrote every question in October 2026 to match the current Professional Data Engineer exam guide, including the newer services and the product names Google uses today.

What's new in the October 2026 update

  • Six full-length exams, 50 questions each, 300 questions in total (up from 100)
  • Every question was written for the current exam guide's five sections, in the same proportions as the real exam:
    • Designing data processing systems (about 22%)
    • Ingesting and processing the data (about 25%)
    • Storing the data (about 20%)
    • Preparing and using data for analysis (about 15%)
    • Maintaining and automating data workloads (about 18%)
  • Coverage of newer exam topics, such as BigQuery AI functions and continuous queries, embeddings and RAG data preparation, Apache Iceberg managed tables and BigLake, Knowledge Catalog, BigQuery sharing, Dataform, Datastream, Managed Service for Apache Kafka, Pub/Sub single message transforms, BigQuery editions and reservations, and Bigtable Data Boost
  • Current product names throughout, with the former name noted where it changed, for example Managed Service for Apache Spark (formerly Dataproc), Managed Service for Apache Airflow (formerly Cloud Composer), Knowledge Catalog (formerly Dataplex Universal Catalog), and Data Studio (formerly Looker Studio)

Explanations that teach, not just grade

Most practice tests tell you which answer is right. These explain why. Every answer option has its own explanation of why it's correct or incorrect for that scenario, and often when it would be the right choice. Every question also has a detailed overall explanation that covers the concept behind the question, why each distractor fails, an exam tip on the pattern to recognize, and links to the relevant Google Cloud documentation. If you get a question wrong, the explanation should leave you understanding the topic, not just the answer.

Questions like the ones you'll see on the exam

The questions are realistic scenarios with the constraints that decide the answer: minimize cost, minimize operational overhead, meet a recovery objective, keep data in a region, follow least privilege. Some questions test exact BigQuery SQL, bq, and gcloud usage. About one in six is multiple select, as on the real exam. Each question was checked against current Google Cloud documentation and reviewed independently.

How to use these exams

Take the first exam before you study to find your gaps, then use the explanations and documentation links to fill them. Save the later exams to check your readiness. The real exam is two hours long with 40 to 50 multiple-choice and multiple-select questions; each practice exam gives you 120 minutes for 50 questions so you can practice your pacing. Aim to score well above 70% before you book the exam.

  • 良い点

  • ● okIt is very useful to check our actual knowledge and build confidenceVery good questions to prepare the exam.very good question's and explanationokBe sure to review the domains that are shown after you finish these practice test questions. They are very helpful. To be clear, the domains listed inside of Udemy right after you finish the practice tests. I originally neglected to do this. I bought Dan’s practice tests in 2022, and then both failed and passed one of them (with a 70%) before failing the actual exam because I didn’t know what to study. I asked Dan for guidance, he was super helpful, I got his books, took his courses, and reattempted the actual exam again in 2023 and passed. Well, it’s been two years alreadyand guess who needs to attempt a renewal exam in the next month. That’s right. I do. :-) So, here I am reviewing with the man who helped get me started. Some things about data engineering will likely not change for quite a while. There may be new things, but we really need to know the core solid. ETL, the infrastructure, the workflows and what’s involved, and what the options are based on the use case, technical constraints, and business requirements, etc. Thank you, Dan, for your guidance, direction, and support! Cheers to your and everyone’s success! - Cory (currently a 14x-certified Google Cloud Professional)This is a great set of tests- compare to what's out there especially. If I was learning from scratch, I would certainly consider taking this guys Course as well.The questions and solution to each question were too good. Provided more information then going through the actual training. Thank you for great compilation!Got certified first try, pretty good to get a feel of what you'll be asked during the exam.But the GCP stack is moving quickly so make sure it is up to date.Great questions and explanations ! Helps me a lot in remembering key concepts and important differences in 2 very close answers, e.g. when to use CloudSQL vs Cloud Spanner (both are strong consistency but Cloud Spanner is more global vs CloudSQL is more regional), etc... Good explanations in each q so I can remember the important points easily without going thru a lot of GCP docs!Good collection of questions and explanations.I had a different thought on designing of row keys.Meaning I assumed they should start with low cardinality columns and end with high cardinality columns. But the solution of one of the questions in the test specifies otherwisefor example:We need to use reversed timestamps: Year-Month-Day. Since, year has low cardinality it is used in the beginning of the sequenceI solved the problem using page translation.There are some problems that are close to the actual problem,I was able to pass the exam.The explanation and topic section are good to take a look. Some questions are too detail or irrelevant to the actual exam.The questions are really good, following official GCP exam styles.Only that some topics in the questions are outdated, especially about Machine Learning, and not necessary for the current exam.GoodI had both of the Practice tests before my certification renewal. And this actually helped me to elaborate my concepts. I truly appreciate the selected questions. It added to my knowledge and gave me on the idea of my lacking knowledge areas. This really helped. ThanksVery well satisfied with the quiz questions and answers. The explanations were also very well given. The most appreciable part were the URLs which has been shared for each question for a glimpse of detailed theorotical explanationVery good questions at a deep technical level. I am sure GCP exam questions will be more detailed with elaborate explanations and they won't provide an easy clue just by looking at the question. These questions in these 2 practice tests are great too.Good way to practice for the exam, though I have to state that my exam questions where more challenging. Nevertheless the practice exams here really helped me to prepare and I can recommend them.I passed the exam today. This material is helpful to get a point, but you still need another one to be comfortable with more topics.I like the well explained correct and incorrect answers, and the links provided for further understanding and review.The practice test was well-structured, with clear questions. Beginners are given medium- to hard-level questions.The questions are detail-oriented and may be a good step to feel how GPDE actual questions may look likeData Engineerの本番試験もこれと同等の内容が出たらとても助かります。
