What Domains Does the Exam Cover and What Are Their Weightings?

The certification exam is divided into four core sections with the following approximate weightings:

1. Designing Scalable and Reliable Applications (~33%)

   • Cloud-native design using microservices
   • Application modernization and architecture decisions (IaaS, PaaS, CaaS, FaaS)
   • Performance, cost, and availability optimization
   • Session management, caching, error handling
   • Logging, monitoring, and metrics
   • Security and secure service-to-service communication
   • Secrets and key management
   • Data security, regulatory compliance, and application authentication

2. Building and Testing Applications (~26%)

   • Setting up local development environments
   • Using Google Cloud tools (Cloud SDK, Cloud Shell, Cloud Workstations)
   • Secure container image builds and CI pipelines (Cloud Build, Artifact Registry)
   • Testing strategies: unit, integration, performance, failover, chaos testing

3. Deploying Applications (~19%)

   • Feature rollout strategies (A/B testing, feature flags, compatibility)
   • Deploying to serverless platforms (Cloud Functions, Cloud Run, App Engine)
   • Deploying to Kubernetes (GKE), defining resource specs, managing RBAC and IAM

4. Integrating with Google Cloud Services (~22%)

   • Connecting to and consuming data from GCP services (Cloud SQL, Firestore, Bigtable, Cloud Storage)
   • Working with Pub/Sub, Eventarc, Cloud Tasks, Cloud Scheduler
   • Making GCP API calls using client libraries (REST/gRPC), service accounts, caching, pagination
   • Monitoring using Google Cloud’s operations suite

Are There Any Prerequisites?

There are no mandatory prerequisites. However, Google recommends:

• At least 3 years of industry experience, including 1+ year building solutions on Google Cloud
• Proficiency in at least one general-purpose programming language
• Familiarity with Google Cloud services including Cloud Functions, App Engine, GKE, Pub/Sub, Cloud SQL
• Understanding of CI/CD pipelines, testing methodologies, and modern DevOps practices

What Are the Key Skills to Focus On?

Here are the areas to prioritize in your study plan:

1. Architecture Decisions
   • Microservices vs monolith
   • Serverless vs containers
   • Regional vs global deployment plans
2. Security and IAM
   • Using Secret Manager and Cloud KMS
   • Service-to-service authentication strategies
   • Identity and access roles (IAM) for devs and apps
3. Development Tools
   • Local emulators, Skaffold, Cloud Code
   • CI pipelines with Cloud Build
4. Testing & Debugging
   • Instrumentation of code for logs, metrics, and traces
   • Performance and load testing of deployments
5. API Management
   • Building scalable APIs with Apigee
   • Managing versions and authentication
6. Reliable Deployment
   • Graceful degradation during deploys or failures
   • GKE workloads, serverless triggers, rollout strategies

Common Mistakes to Avoid

Avoid the following pitfalls:

• Overlooking practical use cases—you must understand how GCP services work together
• Relying solely on reading without hands-on practice—real deployments matter
• Ignoring logging, monitoring, and cost optimization requirements
• Underestimating security questions around key management, IAM, and service accounts
