Simulate the real Google Professional Cloud DevOps Engineer exam with full-length timed sessions. Questions drawn proportionally from all 10 official blueprint domains — the same mix you'll face on test day.
Simulate real exam conditions
For the most realistic PCDOE simulation, start a 60 or 120-question session, put away all notes, set a timer matching the real exam duration (120 minutes), and commit to each answer before moving forward. This trains the time management and decision-making skills the real exam tests.
This free PCDOE mock exam uses the same question distribution as the real Google Professional Cloud DevOps Engineer exam. Each session draws questions proportionally from all 10 official blueprint domains published by Google Cloud, so the topic mix you see accurately reflects what you'll face on test day.
PCDOE Domain Distribution
Design and Plan Database Solutions
Manage Database Solutions
Migrate Database Solutions
Design for Reliability, Scalability, and Disaster Recovery
Bootstrapping a Google Cloud organization for DevOps
Managing service incidents
Managing Google Cloud costs
Building and implementing CI/CD pipelines
Implementing service monitoring strategies
Optimizing service performance
Every question is written by certified engineers against the 2026 PCDOE exam objectives. These are original practice questions — not dumps — so you build real understanding rather than memorising answers.
Both the mock exam and practice test use the same question bank. The difference is in how you use them — and when to use each during your PCDOE study plan.
Practice test — for learning
Use the PCDOE practice test when you are studying a domain. Answer questions, read every explanation immediately, and build understanding. Do 10–30 questions per domain per session. This is your primary study tool for the first 4 weeks.
Go to practice test →Mock exam — for simulation
Use the PCDOE mock exam in the final 1–2 weeks before your test date. Complete a 60 or 120-question session without stopping, manage your time, then review all results at the end. This builds exam-day stamina and surfaces final weak spots.

A company is migrating their on-premises MySQL database to Cloud SQL using Database Migration Service (DMS). The source database is MySQL 5.7, and the target is a Cloud SQL MySQL 8.0 instance. The migration job is set to continuous, but after the full dump phase, the CDC phase keeps failing with the error 'binary log not found'. What is the most likely cause?

A company is using Google Kubernetes Engine (GKE) with multiple node pools. They notice that their monthly costs are higher than expected. Upon review, they find that several preemptible VMs are being recreated frequently, leading to sustained usage costs. What is the most cost-effective solution to reduce costs?

Answer all 10 questions to see your domain score breakdown
Sitting the PCDOE under real exam conditions is a skill in itself. Candidates who underperform often do so not because of knowledge gaps, but because of poor time management or test anxiety. Use your final mock exam sessions to address both.
The PCDOE exam lasts 120 minutes. Do not spend more than 90 seconds on any single question on the first pass. Flag difficult ones and return to them after completing the rest.
On every question, immediately eliminate obviously wrong choices. Even if you are unsure between two options, narrowing to two doubles your odds. Most PCDOE distractors contain a subtle error — re-read the scenario constraint before committing to the answer that sounds most familiar.
Google Cloud writes many PCDOE questions as realistic scenarios. Read the final sentence first — it tells you what is being asked. Then re-read the scenario with the question in mind to avoid wasting time on irrelevant details.
The real PCDOE is a mental marathon lasting 120 minutes. In the week before your exam, complete at least two full timed mock sessions on separate days to build concentration stamina. If you cannot stay focused for 120 minutes in practice, you will struggle on exam day.

Scaled scoring
The PCDOE uses scaled scoring — your raw percentage correct is converted to a score out of 1000. Consistently scoring above 80% on mock exams puts you well above the 720/1000 threshold, giving you a buffer for any unexpected question types on the real exam.
Yes. Courseiva provides free PCDOE mock exam questions across all official exam domains. The platform includes timed simulation, per-domain score breakdown, missed-question review, and readiness tracking. No account required — free forever, supported by advertising.
The practice test is optimised for learning: you see explanations after each question immediately. The mock exam is optimised for simulation: you answer all questions under time pressure and review at the end. Use practice tests for studying and mock exams for benchmarking.
Aim for consistent scores of 80% or above on full-length PCDOE mock exams before booking your test date. The official passing score of 720/1000 corresponds to roughly 72–75% correct answers, so an 80% buffer accounts for difficulty variation and question styles on the real exam.
Most candidates who pass PCDOE on their first attempt complete 3–5 full-length mock exams in the two weeks before their test. This is enough to identify final weak spots, build stamina, and verify readiness without over-stressing or running out of fresh questions.
No — all Courseiva questions are original, written by certified engineers against public Google Cloud exam blueprints. Exam dumps are memorised real exam questions shared illegally. Using dumps violates your Google Cloud certification agreement and can result in your certification being revoked. Our questions make you genuinely competent, not just test-day lucky.
