About PCDOE
Google’s SRE practice applied to Google Cloud: SLIs, SLOs and error budgets, delivery pipelines with Cloud Build and Cloud Deploy, observability, incident management and optimising for cost and performance.
Who it's for. SREs and DevOps engineers running services on Google Cloud.
How to prepare
- Know what to do when an error budget is exhausted, and who decides.
- Incident roles (incident commander, communications lead, operations lead) and blameless postmortems are tested directly.
- Learn Cloud Deploy promotion, canary releases and Binary Authorization.
Sample PCDOE questions
Try these with the answers on the page, then practise the full bank.
- A data ingestion service has an availability objective of 99.5 percent over a 28-day window. At the end of the window, measured availability is 99.8 percent. How much of the error budget remains unspent? Applying SRE principles
- In the SRE hierarchy of service needs, which capability sits at the base, so that incident response, postmortems, and capacity planning all depend on it? Applying SRE principles
- What is the main reason a team writes an error budget policy? Applying SRE principles
- A team shipped 200 production changes last quarter. Thirty-six of those changes needed a hotfix, rollback, or patch to restore normal service. Which DORA metric does this count describe? Applying SRE principles
- A team sends a new build to two percent of live users, watches error rates and latency for an hour, and then raises the share in steps only if those metrics stay healthy. What is this rollout pattern called? Building and implementing CI/CD pipelines
- A retailer needs a release with no user-visible downtime, and it wants traffic restored to the previous version within seconds if the new one misbehaves. It accepts running double capacity during the switch. Which approach fits? Building and implementing CI/CD pipelines
- Customers report slow checkout pages that began right after a deployment. The incident commander is already in the channel. Under standard incident response practice, which action comes first? Managing incidents
- A checkout service has used nearly all of its quarterly error budget, but a large marketing-driven feature is scheduled to ship next week. Under a typical error budget policy, what should the team do? Managing incidents

Questions people ask
Is this PCDOE practice exam free?
Yes. All 200 questions, the timed mock exam and the explanations are free, and there's no account to create.
Are these real exam questions?
No. Real exam questions are confidential under the Google Cloud candidate agreement. These are practice questions written to cover the same domains in the same scenario style, each with an explanation of why the answer is right.
How is the PCDOE mock exam scored?
Questions are drawn from every domain in proportion to the exam guide, and you get a raw percentage with a breakdown by domain. Google Cloud uses scaled scoring, so treat 75% or more here as a sign you're ready rather than a predicted score.
