Free Google Professional Cloud Architect practice exams are available here, covering all six official exam domains. Whether you are preparing for your first attempt or brushing up before a renewal, working through realistic practice questions is one of the most effective ways to build the architectural judgement the exam demands.
What the Professional Cloud Architect exam covers
The exam tests your ability to translate business requirements into cloud architecture and evaluate trade-offs across performance, security, reliability, and cost. Google structures the content across six weighted domains:
- Designing Cloud Solution Architectures (28%) — selecting the right services, migration patterns, and integration approaches
- Managing and Provisioning Solution Infrastructure (18%) — VPC design, IAM, IaC with Terraform, and resource organisation
- Ensuring Solution and Operations Reliability (16%) — SLOs, SLIs, error budgets, incident management, and disaster recovery
- Designing for Security and Compliance (15%) — encryption, VPC Service Controls, Binary Authorization, and data residency
- Analyzing and Optimizing Cloud Solution Performance (13%) — query optimisation, autoscaling, caching, and cost reduction
- Managing Implementation (10%) — CI/CD pipelines, Cloud Deploy, feature flags, and deployment strategies
The exam is 50 to 60 questions over two hours, including case study scenarios that require you to evaluate an architecture before answering several related questions. Passing requires genuine understanding of when to use each service and why.
What is in these practice exams
Each of the six sets contains 20 unique scenario-based questions that mirror the format and difficulty of the real exam. Topics covered across the sets include:
- Cloud Spanner, Bigtable, AlloyDB, and BigQuery selection trade-offs
- GKE autoscaling with HPA, VPA, and Cluster Autoscaler
- Cloud Run, Cloud Functions, and GKE Autopilot for serverless workloads
- Pub/Sub, Dataflow, and Eventarc for event-driven architectures
- Cloud Interconnect, VPN, VPC peering, and Shared VPC networking
- IAM least privilege, Workload Identity Federation, and service account best practices
- SLO error budget calculation and burn rate alerting
- Terraform, Cloud Build, Cloud Deploy, and Binary Authorization for CI/CD
- Data residency, VPC Service Controls, and Cloud KMS for compliance
- Disaster recovery patterns, PITR, and multi-region active-active deployments
The first set is completely free. No account or payment required to get started.
How to use these questions effectively
The Professional Cloud Architect exam rarely has an obviously wrong answer. Most distractors are plausible and technically correct in a different context. When you answer a question, read the explanation even if you got it right. Understanding exactly why each option is correct or incorrect in the specific scenario builds the pattern recognition the exam rewards.
Pay attention to the constraints in each scenario. Keywords like "minimal downtime," "no infrastructure management," "least privilege," and "zero application changes" directly determine which answer is correct among otherwise similar options.
After finishing each set, note which domains you struggled with and review the relevant Google Cloud documentation or Architecture Center guides before moving on. The exam is hard to brute-force through memorisation but straightforward with solid conceptual understanding.
