## What is GCP Data Engineer Prep 2026?

The Professional Data Engineer exam asks you to think like the person who owns the pipeline — which sink, which windowing, which BigQuery layout, and why. Certisimo trains exactly that judgment, one exam-style question at a time.

WHAT'S INSIDE
• 200 exam-style questions across 4 practice sets, written for the Google Cloud Professional Data Engineer exam
• Covers what the exam covers: BigQuery, Dataflow, Pub/Sub, Dataproc, Bigtable, Cloud Composer and more

TRAIN, THEN TEST
Training mode gives you instant feedback as you answer. Test mode runs like the real thing: a countdown clock, no hints, a score at the end, and a review of everything you skipped or missed.

STOP GUESSING WHETHER YOU ARE READY
Your readiness score is computed from your own answers, so you always know how close you are — and what to do next.

EVERYTHING IN YOUR POCKET
• Save the questions that matter and annotate them with notes
• Search the entire bank instantly
• A complete history of every session you have run
• 100% offline, iPhone and iPad, light and dark — and no sign-up, ever
