Description

This course is 600 original questions for the Google Cloud Professional Cloud Database Engineer exam, arranged as six 100-item mock exams. Every exam follows the published blueprint — 32 / 25 / 23 / 20 — and every item is followed by an explanation for each option, so a wrong answer tells you which idea was wrong rather than only that it was wrong.

The questions are written the way the exam is written: a short engineering situation, a stated constraint, and a decision. A team must fit a working set into memory without changing the machine type; a bank must survive a regional loss without losing acknowledged writes; a migration has a 20-minute window and a 5 TB source. You are asked what to do and why, not which menu contains a setting.

WHAT MAKES THIS DIFFERENT

• Blueprint-weighted, not topic-sampled: every exam allocates 32 / 25 / 23 / 20 items to the four official sections, and because those published weights total exactly 100% the allocation is the weight itself, with no rounding and no tolerance band.

• Explanations for all options: correct options explain why they win, and distractors explain what they would break.

• Original items only, written for this course. No recalled exam content and no question-bank copies.

• No invented pass mark: Google does not publish a passing score for this exam, so none is stated and no practice percentage is converted into one.

• No case studies: the published format has none, so none are imitated.

• Configuration is judged, not dictated: items reason about HA topology, connection paths, backup and point-in-time recovery, replication and provisioning automation. Nothing is a click-by-click recipe and nothing needs a live project.

WHAT YOU GET

• Six full-length practice exams of 100 questions each, 84 single-answer and 16 multi-select per exam.

• An explanation for every option, plus a rationale, the exam-guide section, the local study area and a primary reference on every question.

• A blueprint that matches the published weights exactly on all six exams.

• A 51-area study map mapped to the four official sections.

• Study plan, eight-week schedule, two-hour time budget, scoring method and quick-reference sheets.

EXAM FACTS THIS COURSE IS BUILT AROUND

Verified against Google’s certification page and exam guide in October 2026: two hours, $200 USD plus tax, 50–60 multiple-choice and multiple-select questions, offered in English and Japanese, no prerequisites (5+ years of database and IT experience including 2 years of hands-on Google Cloud database work is recommended), no published passing score, and no case-study component.

AN HONEST NOTE ON LENGTH AND TIMING

The live exam asks 50–60 questions in two hours, which is roughly 120–144 seconds per question. Each practice exam here is 100 questions, a deliberately larger bank for broader coverage. Under the same two-hour clock that is about 72 seconds per question, so these sets run slower per item than the real exam and are a comfortable, thorough rehearsal rather than a time simulator. If you want pressure, shorten the clock deliberately.

IMPORTANT DISCLOSURES

• Independent educational content. Not affiliated with, endorsed by, or sponsored by Google. Google Cloud and the certification names are trademarks of Google LLC.

• No claim of exam-day equivalence, no guarantee of a passing result, and no reproduction of live exam content.

• The passing score is not published by Google and is therefore not stated anywhere in this course.

• Product names follow the October 2026 exam guide; Google notes the exam will be updated for recent branding changes, so always confirm current names in the guide.
