Free Google Professional-Cloud-Developer Exam Questions

Question 1

Your web application is deployed to the corporate intranet. You need to migrate the web application to Google Cloud. The web application must be available only to company employees and accessible to employees as they travel. You need to ensure the security and accessibility of the web application while minimizing application changes. What should you do?

A : nfigure the application to check authentication credentials for each HTTP(S) request to the application.

B : nfigure Identity-Aware Proxy to allow employees to access the application through its public IP address.

C : nfigure a Compute Engine instance that requests users to log in to their corporate account. Change the web application DNS to point to the proxy Compute Engine instance. After authenticating, the Compute Engine instance forwards requests to and from the web application.

D : nfigure a Compute Engine instance that requests users to log in to their corporate account. Change the web application DNS to point to the proxy Compute Engine instance. After authenticating, the Compute Engine issues an HTTP redirect to a public IP address hosting the web application.

Answer: B

Question 2

Your application runs smoothly when tested on a local environment, but its performance significantly degrades when deployed on a Compute Engine instance. Your task is to identify the root cause of the issue.

What actions do you think are appropriate?

A : Use Cloud Profiler to determine which functions within the application take the longest amount of time.

B : Add logging commands to the application and use Cloud Logging to check where the latency problem occurs.

C : Use Cloud Debugger snapshots to look at a point-in-time execution of the application.

D : File a ticket with Cloud Support indicating that the application performs faster locally.

Answer: A

Question 3

Working alongside the CI/CD team, you, as a developer, are tasked with identifying and resolving a problem that has arisen with a new feature that your team has recently introduced. The CI/CD team employed HashiCorp Packer to generate a fresh Compute Engine image from your development branch, which proved successful in its creation. However, the image is currently unable to start up and requires investigation by the CI/CD team.

What actions are recommended?

A : Install Packer on your device, build the Compute Engine image locally, and then run it in your personal Google Cloud project.

B : Verify the Compute Engine OS logs through the serial port and confirm access to the serial port by checking the Cloud Logging logs.

C : Create a new feature branch and request the build team to reconstruct the image.

D : Power off the virtual machine in use, export the disk, and mount it locally to access the boot logs.

Answer: B

Question 4

Your team has created an application that is hosted on a Google Kubernetes Engine (GKE) cluster. You need to connect the application to a legacy REST service that is deployed in two GKE clusters in two different regions. You want to connect your application to the target service in a way that is resilient. You also want to be able to run health checks on the legacy service on a separate port. How should you set up the connection? (Choose two.)

A : Traffic Director with a sidecar proxy to connect the application to the service.

B : a proxyless Traffic Director configuration to connect the application to the service.

C : nfigure the legacy service's firewall to allow health checks originating from the proxy.

D : nfigure the legacy service's firewall to allow health checks originating from the application.

E : nfigure the legacy service's firewall to allow health checks originating from the Traffic Director control plane.

Answer: A,C

Question 5

Your team detected a spike of errors in an application running on Cloud Run in your production project. The application is configured to read messages from Pub/Sub topic A, process the messages, and write the messages to topic B. You want to conduct tests to identify the cause of the errors. You can use a set of mock messages for testing. What should you do?

A : ploy the Pub/Sub and Cloud Run emulators on your local machine. Deploy the application locally, and change the logging level in the application to DEBUG or INFO. Write mock messages to topic A, and then analyze the logs.

B : the gcloud CLI to write mock messages to topic A. Change the logging level in the application to DEBUG or INFO, and then analyze the logs.

C : ploy the Pub/Sub emulator on your local machine. Point the production application to your local Pub/Sub topics. Write mock messages to topic A, and then analyze the logs.

D : the Google Cloud console to write mock messages to topic A. Change the logging level in the application to DEBUG or INFO, and then analyze the logs.

Answer: C
