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

• Question 1

  You need to redesign the ingestion of audit events from your authentication service to allow it to handle a large increase in traffic. Currently, the audit service and the authentication system run in the same Compute Engine virtual machine. You plan to use the following Google Cloud tools in the new architecture:Multiple Compute Engine machines, each running an instance of the authentication serviceMultiple Compute Engine machines, each running an instance of the audit servicePub/Sub to send the events from the authentication services.How should you set up the topics and subscriptions to ensure that the system can handle a large volume of messages and can scale efficiently?

  • Create one Pub/Sub topic. Create one pull subscription to allow the audit services to share the messages.
  • Create one Pub/Sub topic. Create one pull subscription per audit service instance to allow the services to share the messages.
  • Create one Pub/Sub topic. Create one push subscription with the endpoint pointing to a load balancer in front of the audit services.
  • Create one Pub/Sub topic per authentication service. Create one pull subscription per topic to be used by one audit service.
  • Create one Pub/Sub topic per authentication service. Create one push subscription per topic, with the endpoint pointing to one audit service.

• Question 2

  Your company has a BigQuery dataset named 'Master' that keeps information about employee travel andexpenses. This information is organized by employee department. That means employees should only be ableto view information for their department. You want to apply a security framework to enforce this requirementwith the minimum number of steps.What should you do?

  • Create a separate dataset for each department. Create a view with an appropriate WHERE clause to select records from a particular dataset for the specific department. Authorize this view to access records from your Master dataset. Give employees the permission to this department-specific dataset.
  • Create a separate dataset for each department. Create a data pipeline for each department to copy appropriate information from the Master dataset to the specific dataset for the department. Give employees the permission to this department-specific dataset.
  • Create a dataset named Master dataset. Create a separate view for each department in the Master dataset. Give employees access to the specific view for their department.
  • Create a dataset named Master dataset. Create a separate table for each department in the Master dataset. Give employees access to the specific table for their department.

• Question 3

  You are using Cloud Build to build a Docker image. You need to modify the build to execute unit and runintegration tests. When there is a failure, you want the build history to clearly display the stage at which thebuild failed.What should you do?

  • Add RUN commands in the Dockerfile to execute unit and integration tests.
  • Create a Cloud Build build config file with a single build step to compile unit and integration tests.
  • Create a Cloud Build build config file that will spawn a separate cloud build pipeline for unit and integration tests.
  • Create a Cloud Build build config file with separate cloud builder steps to compile and execute unit and integration tests.

• Question 4

  You are building a highly available and globally accessible application that will serve static content to users. You need to configure the storage and serving components. You want to minimize management overhead and latency while maximizing reliability for users. What should you do?

  • 1) Create a managed instance group. Replicate the static content across the virtual machines (VMs) 2) Create an external HTTP(S) load balancer. 3) Enable Cloud CDN, and send traffic to the managed instance group.
  • 1) Create an unmanaged instance group. Replicate the static content across the VMs. 2) Create an external HTTP(S) load balancer 3) Enable Cloud CDN, and send traffic to the unmanaged instance group.
  • 1) Create a Standard storage class, regional Cloud Storage bucket. Put the static content in the bucket 2) Reserve an external IP address, and create an external HTTP(S) load balancer 3) Enable Cloud CDN, and send traffic to your backend bucket
  • 1) Create a Standard storage class, multi-regional Cloud Storage bucket. Put the static content in the bucket. 2) Reserve an external IP address, and create an external HTTP(S) load balancer. 3) Enable Cloud CDN, and send traffic to your backend bucket.

• Question 5

  You recently migrated a monolithic application to Google Cloud by breaking it down into microservices. One of the microservices is deployed using Cloud Functions. As you modernize the application, you make a change to the API of the service that is backward-incompatible. You need to support both existing callers who use the original API and new callers who use the new API. What should you do?

  • Leave the original Cloud Function as-is and deploy a second Cloud Function with the new API. Use a load balancer to distribute calls between the versions.
  • Leave the original Cloud Function as-is and deploy a second Cloud Function that includes only the changed API. Calls are automatically routed to the correct function.
  • Leave the original Cloud Function as-is and deploy a second Cloud Function with the new API. Use Cloud Endpoints to provide an API gateway that exposes a versioned API.
  • Re-deploy the Cloud Function after making code changes to support the new API. Requests for both versions of the API are fulfilled based on a version identifier included in the call.
