Your application is composed of a set of loosely coupled services orchestrated by code executed on Compute Engine. You want your application to easily bring up new Compute Engine instances that find and use a specific version of a service. How should this be configured?

A.

Define your service endpoint information as metadata that is retrieved at runtime and used to connect to the desired service.

B.

Define your service endpoint information as label data that is retrieved at runtime and used to connect to the desired service.

C.

Define your service endpoint information to be retrieved from an environment variable at runtime and used to connect to the desired service.

D.

Define your service to use a fixed hostname and port to connect to the desired service. Replace the service at the endpoint with your new version.

Your team is developing a Cloud Function triggered by Cloud Storage Events. You want to accelerate testing and development of your Cloud Function while following Google-recommended best practices. What should you do?

A.

Install the Functions Frameworks library, and configure the Cloud Function on localhost. Make a copy of the function, and make edits to the new version Test the new version using cur1.

B.

Make a copy of the Cloud Function, and rewrite the code to be HTTP-triggered Edit and test the new version

by triggering the HTTP endpoint. Send mock requests to the new function to evaluate the functionality.

C.

Make a copy of the Cloud Function in the Google Cloud Console Use the Cloud console's in-line editor to

make source code changes to the new function Modify your web application to call the new function and test the new version in production.

D.

Create a new Cloud Function that is triggered when Cloud Audit Logs detects the

cloudfunctions. functions. sourceCodeSet operation in the original Cloud Function Send mock

requests to the new function to evaluate the functionality.

You have an on-premises application that authenticates to the Cloud Storage API using a user-managed service account with a user-managed key. The application connects to Cloud Storage using Private Google Access over a Dedicated Interconnect link. You discover that requests from the application to access objects in the Cloud Storage bucket are failing with a 403 Permission Denied error code. What is the likely cause of this issue?

A.

The folder structure inside the bucket and object paths have changed.

B.

The permissions of the service account’s predefined role have changed.

C.

The service account key has been rotated but not updated on the application server.

D.

The Interconnect link from the on-premises data center to Google Cloud is experiencing a temporary outage.

Your analytics system executes queries against a BigQuery dataset. The SQL query is executed in batch and passes the contents of a SQL file to the BigQuery CLI. Then it redirects the BigQuery CLI output to another process. However, you are getting a permission error from the BigQuery CLI when the queries are executed. You want to resolve the issue. What should you do?

A.

Grant the service account BigQuery Data Viewer and BigQuery Job User roles.

B.

Grant the service account BigQuery Data Editor and BigQuery Data Viewer roles.

C.

Create a view in BigQuery from the SQL query and SELECT* from the view in the CLI.

D.

Create a new dataset in BigQuery, and copy the source table to the new dataset Query the new dataset and table from the CLI.

Your team develops services that run on Google Kubernetes Engine. Your team’s code is stored in Cloud Source Repositories. You need to quickly identify bugs in the code before it is deployed to production. You want to invest in automation to improve developer feedback and make the process as efficient as possible. What should you do?

A.

Use Spinnaker to automate building container images from code based on Git tags.

B.

Use Cloud Build to automate building container images from code based on Git tags.

C.

Use Spinnaker to automate deploying container images to the production environment.

D.

Use Cloud Build to automate building container images from code based on forked versions.

Your application performs well when tested locally, but it runs significantly slower when you deploy it to App Engine standard environment. You want to diagnose the problem. What should you do?

A.

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

B.

Use Stackdriver Debugger Snapshots to look at a point-in-time execution of the application.

C.

Use Stackdriver Trace to determine which functions within the application have higher latency.

D.

Add logging commands to the application and use Stackdriver Logging to check where the latency problem occurs.

You are designing a deployment technique for your new applications on Google Cloud. As part of your deployment planning, you want to use live traffic to gather performance metrics for both new and existing applications. You need to test against the full production load prior to launch. What should you do?

A.

Use canary deployment

B.

Use blue/green deployment

C.

Use rolling updates deployment

D.

Use A/B testing with traffic mirroring during deployment

Your team is developing unit tests for Cloud Function code. The code is stored in a Cloud Source Repositories repository. You are responsible for implementing the tests. Only a specific service account has the necessary permissions to deploy the code to Cloud Functions. You want to ensure that the code cannot be deployed without first passing the tests. How should you configure the unit testing process?

A.

Configure Cloud Build to deploy the Cloud Function. If the code passes the tests, a deployment approval is sent to you.

B.

Configure Cloud Build to deploy the Cloud Function, using the specific service account as the build agent. Run the unit tests after successful deployment.

C.

Configure Cloud Build to run the unit tests. If the code passes the tests, the developer deploys the Cloud Function.

D.

Configure Cloud Build to run the unit tests, using the specific service account as the build agent. If the code passes the tests, Cloud Build deploys the Cloud Function.

Your application requires service accounts to be authenticated to GCP products via credentials stored on its host Compute Engine virtual machine instances. You want to distribute these credentials to the host instances as securely as possible. What should you do?

A.

Use HTTP signed URLs to securely provide access to the required resources.

B.

Use the instance’s service account Application Default Credentials to authenticate to the required resources.

C.

Generate a P12 file from the GCP Console after the instance is deployed, and copy the credentials to the host instance before starting the application.

D.

Commit the credential JSON file into your application’s source repository, and have your CI/CD process package it with the software that is deployed to the instance.

Your company wants to expand their users outside the United States for their popular application. The

company wants to ensure 99.999% availability of the database for their application and also wants to minimize the read latency for their users across the globe.

Which two actions should they take? (Choose two.)

A.

Create a multi-regional Cloud Spanner instance with "nam-asia-eur1" configuration.

B.

Create a multi-regional Cloud Spanner instance with "nam3" configuration.

C.

Create a cluster with at least 3 Spanner nodes.

D.

Create a cluster with at least 1 Spanner node.

E.

Create a minimum of two Cloud Spanner instances in separate regions with at least one node.

F.
