Cloud Developer Practice Exam: Test Your Knowledge 2025

You are designing a cloud-native application that needs to handle unpredictable traffic spikes during product launches. The application should scale automatically and minimize operational overhead. Which Google Cloud service is the BEST choice for hosting this application?

Your application deployed on Google Kubernetes Engine needs to access Cloud Storage buckets. Following security best practices, how should you configure authentication?

You are building a microservices architecture where Service A needs to call Service B asynchronously. Service B processes requests that may take several minutes. Which Google Cloud service should you use to decouple these services?

Your team is developing a globally distributed application that requires single-digit millisecond read latency for user profile data across multiple regions. The data is frequently read but infrequently updated. What is the MOST cost-effective solution?

You need to implement a circuit breaker pattern for your microservices running on Google Kubernetes Engine to prevent cascading failures. What should you implement?

You are developing a REST API using Python and Flask. Which approach should you use to run unit tests locally before deploying to Cloud Run?

Your application uses Cloud Build for CI/CD. You need to run integration tests that require access to a Cloud SQL database. What is the recommended approach?

You are implementing continuous integration for a Node.js application. Your Cloud Build configuration needs to cache npm dependencies between builds to reduce build time. What should you configure?

Your development team needs to test a new feature that integrates with Cloud Pub/Sub. You want to run tests locally without incurring costs or affecting production topics. What should you use?

You are implementing automated testing for a microservices application. Some tests are flaky and occasionally fail due to timing issues with external API calls. What is the BEST practice to handle this?

You have containerized your application and need to deploy it to Cloud Run. The container image is stored in Artifact Registry. What is the command to deploy it?

Your application requires zero downtime during deployments to Google Kubernetes Engine. The application takes 30 seconds to initialize before it can serve traffic. How should you configure your deployment?

You need to implement blue-green deployment for your application on Cloud Run to minimize risk during releases. What is the recommended approach?

Your Cloud Build pipeline needs to deploy to Google Kubernetes Engine after building a container image. The pipeline should only deploy if all tests pass. What should you configure?

Your organization requires that all container images be scanned for vulnerabilities before deployment to production. How should you implement this in your Cloud Build pipeline?

Your application on Cloud Run needs to access secrets stored in Secret Manager. What is the BEST practice for providing these secrets to your application?

Your application experiences high latency during peak hours. After investigation, you find that database queries are the bottleneck. What should you implement to improve performance?

You need to monitor the performance of your Cloud Run service and receive alerts when the 95th percentile latency exceeds 500ms for 5 minutes. How should you configure this?

Your microservices application needs distributed tracing to diagnose performance issues across service boundaries. Multiple services communicate via HTTP and Pub/Sub. What should you implement?

Your application running on GKE needs to process files uploaded to Cloud Storage. You want to trigger processing automatically when files are uploaded. What is the MOST efficient architecture?
