Google Cloud PCA exam guide covering architecture design, trade-offs, reliability, security, and cost decisions.
This Google Cloud Professional Cloud Architect guide helps Google Cloud PCA candidates focus on what the exam tests, where close answers usually split, and which review page to use next.
Use the study plan to organize cloud architecture, IAM, reliability, and service decisions, the cheat sheet for scenario triage, the sample questions for applied practice, the FAQ for scope checks, the resources page for Google Cloud references, and the glossary when service names blur together.

| Lane | What to master | Common weak answer |
|---|---|---|
| Solution design | Choose compute, storage, network, data, and integration patterns that match business and technical constraints. | Starting with a favorite service instead of constraints and trade-offs. |
| Security and compliance | Apply IAM, organization policy, service accounts, encryption, network boundaries, and compliance evidence. | Using broad roles or public access for speed. |
| Reliability and operations | Design for availability, disaster recovery, monitoring, logging, SLOs, and incident response. | Ignoring failure domains, backup validation, or operations ownership. |
| Migration and modernization | Select migration waves, hybrid connectivity, data transfer, refactoring, and cutover strategies. | Replatforming everything without dependency and risk analysis. |
| Cost and performance | Optimize capacity, autoscaling, storage class, query behavior, and managed-service fit. | Scaling before measuring bottlenecks and cost drivers. |
Architect questions are constraint trade-offs: requirement, service fit, failure domain, security boundary, operations, and cost.
