Study guides, tips, and insights to help you pass the Professional Cloud Architect certification — with unlimited free mocks better than limited paid samplers.
Comprehensive study strategies and exam-taking tips from certified professionals. Learn what topics to focus on, how to manage your time, and the best resources for preparation.
The Professional Cloud Architect exam draws its scenario questions from Google's official case-study set. Two case studies appear on each standard exam, and case-study questions make up roughly 20-30% of the total score, so knowing all seven - not just the classic three - is what separates a pass from a near-miss.
Hospital / healthcare data migration scenario: HIPAA compliance, multi-cloud latency, and moving legacy EHR systems onto GCP. Deep dive →
Gaming / real-time multiplayer analytics scenario: global leaderboard consistency with Spanner vs Bigtable. Deep dive →
Connected-vehicle / IoT fleet scenario: 2 million vehicles streaming telemetry, predictive maintenance with BigQuery ML. Deep dive →
Live-streamed sports scenario: global broadcast latency, transient audience spikes, and media CDN choices.
Omnichannel retail scenario: hybrid/legacy migration, point-of-sale reliability, and inventory analytics modernization.
Media / streaming scenario: video transcoding pipelines, DRM key management (Cloud KMS), and global content delivery.
Automotive / connected-cars scenario: fleet telemetry ingestion, predictive maintenance, and analytics-driven R&D.
Study tip: the classic three (EHR, Mountkirk, TerramEarth) have the most public study material, but the newer four show up on the current exam. Practice with our free scored PCA mocks - all seven scenarios are included.

Common questions about the 2026 exam and our practice platform.
The PCA is often considered more difficult because it relies heavily on analyzing complex case studies and choosing the "most correct" solution among several working options, rather than just knowing service names.
If you have less than a year of hands-on experience, yes. The ACE exam builds the foundational command-line and console skills that the PCA exam assumes you already have.
The core case studies (EHR Healthcare, Mountkirk, TerramEarth) remain consistent for long periods, but the underlying technical requirements and "modern" solutions evolve as new GCP products are released.
Not at this time. We provide an interactive, timed testing environment to better simulate the actual exam experience, which is the most effective way to prepare.
