Google Certified Professional - Cloud Developer - Professional-Cloud-Developer Exam Practice Test

You are evaluating developer tools to help drive Google Kubernetes Engine adoption and integration with your development environment, which includes VS Code and IntelliJ. What should you do?

You have an application running in a production Google Kubernetes Engine (GKE) cluster. You use Cloud Deploy to automatically deploy your application to your production GKE cluster. As part of your development process, you are planning to make frequent changes to the application's source code and need to select the tools to test the changes before pushing them to your remote source code repository. Your toolset must meet the following requirements:
- Test frequent local changes automatically.
- Local deployment emulates production deployment.
Which tools should you use to test building and running a container on your laptop using minimal resources?

You are designing a Node.js-based mobile news feed application that stores data on Google Cloud. You need to select the application's database. You want the database to have zonal resiliency out of the box, low latency responses, ACID compliance, an optional middle tier, semi- structured data storage, and network-partition-tolerant and offline-mode client libraries. What should you do?

Your application is deployed on hundreds of Compute Engine instances in a managed instance group (MIG) in multiple zones. You need to deploy a new instance template to fix a critical vulnerability immediately but must avoid impact to your service. What setting should be made to the MIG after updating the instance template?

You are using Cloud Run to host a web application. You need to securely obtain the application project ID and region where the application is running and display this information to users. You want to use the most performant approach. What should you do?

You want to upload files from an on-premises virtual machine to Google Cloud Storage as part of a data migration. These files will be consumed by Cloud DataProc Hadoop cluster in a GCP environment.
Which command should you use?

You maintain a CI/CD pipeline for an application running on GKE. You use Cloud Build to create container images and push the images to Artifact Registry. When you build the image, you use the latest tag in your pipeline.
You recently had to roll back a deployment 24 hours after rollout. The rollback process was difficult because the latest tag had been overwritten. You need to prevent this issue in the future.
You want to use the most efficient approach. What should you do?

Your code is running on Cloud Functions in project A. It is supposed to write an object in a Cloud Storage bucket owned by project B. However, the write call is failing with the error "403 Forbidden".
What should you do to correct the problem?

You work for an organization that manages an ecommerce site. Your application is deployed behind a global HTTP(S) load balancer. You need to test a new product recommendation algorithm. You plan to use A/B testing to determine the new algorithm's effect on sales in a randomized way. How should you test this feature?

Your application is deployed in a Google Kubernetes Engine (GKE) cluster. When a new version of your application is released, your CI/CD tool updates the spec.template.spec.containers[0].image value to reference the Docker image of your new application version. When the Deployment object applies the change, you want to deploy at least
1 replica of the new version and maintain the previous replicas until the new replica is healthy.
Which change should you make to the GKE Deployment object shown below?
