Overview

About the exam

The Professional Cloud Architect certification validates the ability to design, develop, and manage secure, scalable, and cost-effective cloud architectures. Google recommends 3+ years of industry experience, including 1+ years designing and managing solutions on Google Cloud.

The current v6.1 case studies are Altostrat Media, Cymbal Retail, EHR Healthcare, and KnightMotives Automotive. The exam guide now covers securing AI explicitly, naming Model Armor and Sensitive Data Protection, and uses Google's current product naming — Gemini Enterprise Agent Platform in place of Vertex AI.

Analyzing and optimizing technical and business processes1 / 5

A platform team manages VPCs, buckets, and service accounts with Terraform. Security wants a pull request to fail with a report naming the specific resources that would violate the organization's security requirements, before anything is created, and wants the same constraint definitions reused when auditing already-deployed resources. Which approach meets this?

AlexFull explanation from Alex

This is testing and validation applied to infrastructure rather than application code: the Terraform plan is the artifact under test, and the constraint library is the test suite. The value of validating the plan is feedback at review time, where a violation costs a comment rather than an incident, and the same constraints can then be applied to already-deployed resources so that drift and pre-existing violations surface too. Preventative controls at apply time and detective controls after deployment remain useful, but neither gives a reviewer a per-resource verdict before the change is made.

Designing and planning a cloud solution architecture2 / 5

Your company operates a real-time fraud detection system requiring single-digit millisecond lookups against a 500 GB key-value dataset updated in near-real-time from streaming sources. Which database is best suited?

AlexFull explanation from Alex

Cloud Bigtable is a fully managed wide-column NoSQL database for large amounts of single-keyed data. For SSD storage, Google documents expected read/write latency as single-digit milliseconds, making it suitable for latency-sensitive operational workloads such as fraud lookups over hundreds of gigabytes. The original sub-millisecond wording was too strong for Bigtable SSD and has been corrected to single-digit millisecond. BigQuery is for analytics, Cloud SQL is not optimized for this key-value scale and access pattern, and the listed Memorystore for Redis option is an in-memory cache rather than the best persistent 500 GB database choice.

Managing and provisioning a cloud solution infrastructure5 / 5

A media company stores petabytes of video files in Cloud Storage. They need to automatically move older content to lower-cost storage classes based on age while keeping recently uploaded content in the Standard class. How should they configure this?

AlexFull explanation from Alex

Object Lifecycle Management (OLM) automates storage class transitions and object deletion based on configurable rules. Per Google Cloud docs, you define lifecycle rules with conditions (age, storage class, prefix/suffix) and actions (SetStorageClass or Delete). Storage classes from most to least expensive: Standard, Nearline (30-day minimum storage), Coldline (90-day minimum), Archive (365-day minimum). The SetStorageClass action transitions objects downward: Standard to Nearline to Coldline to Archive. Rules are evaluated automatically — no custom code, scheduled jobs, or external orchestration needed. Changes to lifecycle configuration may take up to 24 hours to take effect. OLM is the recommended approach over custom Cloud Run functions, Transfer Service schedules, or Cloud Composer DAGs, which all add unnecessary complexity, cost, and maintenance burden. For petabyte-scale media storage, OLM scales automatically with no per-object overhead. Exam tip: Always prefer built-in OLM over custom solutions. Minimum storage durations: Nearline=30d, Coldline=90d, Archive=365d. Early deletion fees apply if objects are deleted before minimum duration.

Exam domains

What's on the exam

Designing and planning the architecture itself carries the most weight at 25% — translating business requirements into a design, measuring it against the Well-Architected Framework, selecting the network, storage, and compute components it runs on, and planning the migration path. Provisioning that infrastructure and designing for security and compliance are tied at 17.5% each: one covers configuring the network, storage, and compute systems plus Gemini-driven ML workflows; the other covers IAM, encryption, resource hierarchy, and regulatory requirements like data sovereignty and industry certification. Process analysis (SDLC, CI/CD, stakeholder and change management) takes 15%. Managing implementation and ensuring operational excellence close the blueprint at 12.5% each.

Two case studies, drawn from a pool of four recurring scenarios, make up 20–30% of the exam and cut across every domain at once: a single case-study question can test architecture design, security posture, and cost tradeoffs together, which is why this is the one GCP exam where reading comprehension under time pressure matters as much as technical recall.

Exam blueprint: GCP-PCA

Designing and planning a cloud solution architecture~25%

Translate business needs into a cloud architecture, hold it to the Well-Architected Framework's technical bar, choose the right mix of networking, storage, and compute building blocks it runs on, and plan both the migration path and where the solution goes next.

≈ 30 h

Managing and provisioning a cloud solution infrastructure~18%

Configure network topologies, storage systems, and compute systems to provision a cloud solution infrastructure, and use Gemini Enterprise Agent Platform to orchestrate end-to-end ML workflows. Also covers configuring prebuilt AI solutions and APIs for a given use case.

≈ 21 h

Designing for security and compliance~18%

Design for security using IAM, resource hierarchy, encryption, and network controls such as VPC Service Controls, and design for compliance with legislation, industry certifications, and audit requirements.

≈ 21 h

Analyzing and optimizing technical and business processes~15%

Analyze and define technical processes such as the software development lifecycle, CI/CD, and disaster recovery, and analyze and define business processes including stakeholder management, change management, and cost optimization.

Questions

Frequently asked questions

Which pitfalls should I review when preparing for Professional Cloud Architect?

Topics to review include Case Study Time Management, Managed vs Unmanaged, Hybrid/Multi-Cloud, Cost Optimization, AI Integration, Migration Strategies. Work through examples to check that you understand the distinctions and can explain your answer.

How is the Professional Cloud Architect exam weighted?

Designing and planning a solution architecture is the largest section at 25%, with provisioning infrastructure and designing for security and compliance at 17.5% each. Analysing and optimizing processes takes 15%, and managing implementation and operations excellence 12.5% each. Design and security together are well over half the exam.

How do you renew Professional Cloud Architect?

The certification lasts two years and renews through a shorter exam of 25 questions in one hour inside the eligibility window. That renewal exam is built around case studies, which make up 90 to 100% of it, and it includes one case study aligned to generative AI solutions. It is a different exam from the original, not a shortened copy of it.

What experience does Professional Cloud Architect assume?

Google Cloud recommends three or more years in the industry with at least one year designing and managing solutions on Google Cloud, and enforces neither. The catalog budget is 120 hours, the highest of the Google Cloud exams we cover alongside DevOps and machine learning. The case-study format is what drives that number: the exam asks for judgement across a whole fictional business rather than for individual service facts.

How soon can you retake Professional Cloud Architect?

Fourteen days after the first failure, 60 days after the second and 365 days after the third, with a maximum of four attempts in any two-year period. The escalation is steep enough that a rushed second attempt is usually the wrong call.

Should you take Associate Cloud Engineer first?

It is not required, and the two exams test different things: Associate Cloud Engineer asks how you would deploy and operate resources, while the architect exam asks what should be built and why. Most people take the associate exam first because it maps to work they already do. If you already design systems on Google Cloud, going straight to the professional exam is reasonable.
