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

To perform unit and integration tests during the Docker image build process using Cloud Build, you need to make modifications. In the event of a failure, you want the build history to clearly indicate the stage at which the build failed.

What actions do you need to take?

A : Create a Cloud Build build config file with a single build step to compile unit and integration tests.

B : Create a Cloud Build build config file that will spawn a separate cloud build pipeline for unit and integration tests.

C : Add RUN commands in the Dockerfile to execute unit and integration tests.

D : Create a Cloud Build build config file with separate cloud builder steps to compile and execute unit and integration tests.

Question 3

You are using Cloud Run to host a global ecommerce web application. Your company’s design team is creating a new color scheme for the web app. You have been tasked with determining whether the new color scheme will increase sales. You want to conduct testing on live production traffic. How should you design the study?

A : an external HTTP(S) load balancer to route a predetermined percentage of traffic to two different color schemes of your application. Analyze the results to determine whether there is a statistically significant difference in sales.

B : an external HTTP(S) load balancer to route traffic to the original color scheme while the new deployment is created and tested. After testing is complete, reroute all traffic to the new color scheme. Analyze the results to determine whether there is a statistically significant difference in sales.

C : an external HTTP(S) load balancer to mirror traffic to the new version of your application. Analyze the results to determine whether there is a statistically significant difference in sales

D : able a feature flag that displays the new color scheme to half of all users. Monitor sales to see whether they increase for this group of users.

Answer: D

Question 4

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

B : a Stackdriver counter metric for endpoint:/api/alpha/*.

C : port the logs to Cloud Storage and count lines matching /api/alpha.

D : port the logs to Cloud Pub/Sub and count lines matching /api/alpha.
