Question 13

- (Exam Topic 2)
You are developing a new application that has the following design requirements: Creation and changes to the application infrastructure are versioned and auditable.
The application and deployment infrastructure uses Google-managed services as much as possible. The application runs on a serverless compute platform.
How should you design the application’s architecture?

A. * 1. Store the application and infrastructure source code in a Git repository.* 2. Use Cloud Build to deploy the application infrastructure with Terraform.* 3. Deploy the application to a Cloud Function as a pipeline step.

B. * 1. Deploy Jenkins from the Google Cloud Marketplace, and define a continuous integration pipeline in Jenkins.* 2. Configure a pipeline step to pull the application source code from a Git repository.* 3. Deploy the application source code to App Engine as a pipeline step.

C. * 1. Create a continuous integration pipeline on Cloud Build, and configure the pipeline to deploy the application infrastructure using Deployment Manager templates.* 2. Configure a pipeline step to create a container with the latest application source code.* 3. Deploy the container to a Compute Engine instance as a pipeline step.

D. * 1. Deploy the application infrastructure using gcloud commands.* 2. Use Cloud Build to define a continuous integration pipeline for changes to the application source code.* 3. Configure a pipeline step to pull the application source code from a Git repository, and create a containerized application.* 4. Deploy the new container on Cloud Run as a pipeline step.

Question 14

- (Exam Topic 2)
Your operations team has asked you to create a script that lists the Cloud Bigtable, Memorystore, and Cloud SQL databases running within a project. The script should allow users to submit a filter expression to limit the results presented. How should you retrieve the data?

A. Use the HBase API, Redis API, and MySQL connection to retrieve database list

B. Combine the results, and then apply the filter to display the results

C. Use the HBase API, Redis API, and MySQL connection to retrieve database list

D. Filter the results individually, and then combine them to display the results

E. Run gcloud bigtable instances list, gcloud redis instances list, and gcloud sql databases lis

F. Use a filter within the application, and then display the results

G. Run gcloud bigtable instances list, gcloud redis instances list, and gcloud sql databases lis

H. Use --filter flag with each command, and then display the results

Correct Answer:D

Most gcloud commands return a list of resources on success. By default they are pretty-printed on the standard output. The --format=NAME[ATTRIBUTES](PROJECTION) and --filter=EXPRESSION flags along with projections can be used to format and change the default output to a more meaningful result. Use the --format flag to change the default output format of a command. For details run $ gcloud topic formats.

Question 16

- (Exam Topic 2)
Your team manages a Google Kubernetes Engine (GKE) cluster where an application is running. A different team is planning to integrate with this application. Before they start the integration, you need to ensure that the other team cannot make changes to your application, but they can deploy the integration on GKE. What should you do?

A. Using Identity and Access Management (IAM), grant the Viewer IAM role on the cluster project to the other team.

B. Create a new GKE cluste

C. Using Identity and Access Management (IAM), grant the Editor role on the cluster project to the other team.

D. Create a new namespace in the existing cluste

E. Using Identity and Access Management (IAM), grant the Editor role on the cluster project to the other team.

F. Create a new namespace in the existing cluste

G. Using Kubernetes role-based access control (RBAC), grant the Admin role on the new namespace to the other team.

Correct Answer:D

Question 17

- (Exam Topic 2)
You are using the Cloud Client Library to upload an image in your application to Cloud Storage. Users of the application report that occasionally the upload does not complete and the client library reports an HTTP 504 Gateway Timeout error. You want to make the application more resilient to errors. What changes to the application should you make?

A. Write an exponential backoff process around the client library call.

B. Write a one-second wait time backoff process around the client library call.

C. Design a retry button in the application and ask users to click if the error occurs.

D. Create a queue for the object and inform the users that the application will try again in 10 minutes.

Correct Answer:A

Question 18

- (Exam Topic 2)
Before promoting your new application code to production, you want to conduct testing across a variety of different users. Although this plan is risky, you want to test the new version of the application with production users and you want to control which users are forwarded to the new version of the application based on their operating system. If bugs are discovered in the new version, you want to roll back the newly deployed version of the application as quickly as possible.
What should you do?

A. Deploy your application on Cloud Ru

B. Use traffic splitting to direct a subset of user traffic to the new version based on the revision tag.

C. Deploy your application on Google Kubernetes Engine with Anthos Service Mes

D. Use traffic splitting to direct a subset of user traffic to the new version based on the user-agent header.

E. Deploy your application on App Engin

F. Use traffic splitting to direct a subset of user traffic to the new version based on the IP address.

G. Deploy your application on Compute Engin

H. Use Traffic Director to direct a subset of user traffic to the new version based on predefined weights.

Correct Answer:B
