Your pipeline is green. Your cluster is healthy. Your dashboards are full. So why did the release at 14:05 still take the checkout page down for nine minutes, and why can nobody say which change caused it?

Prepare for the Google Cloud Professional Cloud DevOps Engineer exam with 600 original questions across six full-length mock exams of 100 items each. Every exam is blueprint-weighted against the five published sections (20 / 25 / 18 / 25 / 12), so each one rehearses the whole blueprint rather than a random topic dump.

This is an engineer's exam, and it expects judgement rather than recall: designing the resource hierarchy and Shared VPC layout that a hundred teams will live inside; choosing between Terraform, Config Connector, Infrastructure Manager and the Cloud Foundation Toolkit blueprints; building pipelines in Cloud Build and Cloud Deploy with triggers, approvals, Kustomize overlays and Skaffold loops; deciding between rehosting a pipeline and rebuilding it; running fleets of clusters with release channels and maintenance windows; defining SLIs, SLOs, error budgets and the point where reliability spending stops being worth it; choosing canary, blue/green, rolling or feature-flagged release strategies and the telemetry that decides whether a rollout continues; securing the supply chain with Artifact Analysis, Binary Authorization and SLSA-style provenance; and running observability that a responder can actually use — the Ops Agent, OpenTelemetry, managed Prometheus collection, log-based metrics, sinks, redaction, burn-rate alerting, traces and correlation — before closing the loop with Spot VMs, commitments, recommenders and workload-level cost control.

WHY THIS BANK IS DIFFERENT

• Six exams, 600 original items, no duplicate stems anywhere in the bank, and a token-overlap test that rejects reworded repeats

• Exact blueprint weighting on every exam: 20 / 25 / 18 / 25 / 12, which is what Google publishes and which totals exactly 100% — no rounding was needed and none was applied

• Mixed item types exactly as the exam publishes them: 84 single-answer and 16 multi-select, with the selection count stated in every multi-select stem

• No case studies — the published PCDOE format has no case-study component, so none is invented to look like another certification

• Configuration IS in scope, because this exam tests it: items describe pipeline definitions, alerting policies, log routes, IAM boundaries and autoscaling settings, and ask what a team should do and why — never how to click through a console

• Every option explained — why the right answer wins and why each distractor loses for this question

• Every item cites the official exam-guide section it maps to and a primary reference

• 59 local study-map skills, all covered, so you can revise by weakness rather than by exam number
