   You want to send and consume Cloud Pub/Sub messages from your App Engine application. The Cloud Pub/Sub API is currently disabled. You will use a service account to authenticate your application to the API. You want to make sure your application can use Cloud Pub/Sub. What should you do?

   • AEnable the Cloud Pub/Sub API in the API Library on the GCP Console.
   • BRely on the automatic enablement of the Cloud Pub/Sub API when the Service Account accesses it.
   • CUse Deployment Manager to deploy your application. Rely on the automatic enablement of all APIs used by the application being deployed.
   • DGrant the App Engine Default service account the role of Cloud Pub/Sub Admin. Have your application enable the API on the first connection to Cloud Pub/ Sub.

   Show answer

   Answer: A

   Explanation

   Correct Answer is (A) Quickstart: using the Google Cloud Console This page shows you how to perform basic tasks in Pub/Sub using the Google Cloud Console. Note: If you are new to Pub/Sub, we recommend that you start with the interactive tutorial. Before you begin Set up a Cloud Console project. Set up a project Click to: Create or select a project. Enable the Pub/Sub API for that project. You can view and manage these resources at any time in the Cloud Console. Install and initialize the Cloud SDK. Note: You can run the gcloud tool in the Cloud Console without installing the Cloud SDK. To run the gcloud tool in the Cloud Console, use Cloud Shell . https://cloud.google.com/pubsub/docs/quickstart-console

4. Question 204 · 325 in bank

   You need to monitor resources that are distributed over different projects in Google Cloud Platform. You want to consolidate reporting under the same Stackdriver Monitoring dashboard. What should you do?

   • AUse Shared VPC to connect all projects, and link Stackdriver to one of the projects.
   • BFor each project, create a Stackdriver account. In each project, create a service account for that project and grant it the role of Stackdriver Account Editor in all other projects.
   • CConfigure a single Stackdriver account, and link all projects to the same account.
   • DConfigure a single Stackdriver account for one of the projects. In Stackdriver, create a Group and add the other project names as criteria for that Group.

   Show answer

   Answer: C

   Explanation

   First of all D is incorrect, Groups are used to define alerts on set of resources(such as VM instances, databases, and load balancers). FYI tried adding Two projects into a group it did not allowed me as the "AND"/"OR" criteria for the group failed with this combination of resources. C is correct because, When you intially click on Monitoring(Stackdriver Monitoring) it creates a workspac(a stackdriver account) linked to the ACTIVE(CURRENT) Project from which it was clicked. Now if you change the project and again click onto Monitoring it would create an another workspace(a stackdriver account) linked to the changed ACTIVE(CURRENT) Project, we don't want this as this would not consolidate our result into a single dashboard(workspace/stackdriver account). If you have accidently created two diff workspaces merge them under Monitoring > Settings > Merge Workspaces > MERGE. If we have only one workspace and two projects we can simply add other GCP Project under Monitoring > Settings > GCP Projects > Add GCP Projects. In both of these cases we did not create a GROUP, we just linked GCP Project to the workspace(stackdriver account).

5. Question 205 · 325 in bank

   You are deploying an application to a Compute Engine VM in a managed instance group. The application must be running at all times, but only a single instance of the VM should run per GCP project. How should you configure the instance group?

   • ASet autoscaling to On, set the minimum number of instances to 1, and then set the maximum number of instances to 1.
   • BSet autoscaling to Off, set the minimum number of instances to 1, and then set the maximum number of instances to 1.
   • CSet autoscaling to On, set the minimum number of instances to 1, and then set the maximum number of instances to 2.
   • DSet autoscaling to Off, set the minimum number of instances to 1, and then set the maximum number of instances to 2.

   Show answer

   Answer: A

   Explanation

   In my GCP console, I created a managed instance group for each answer. For each answer I deleted the instance that was created as a simple test to prove or disprove each answer. In answer A, another instance was created after I deleted the instance In answer B, no other instance was created after I deleted the instance In answer C, another instance was created after I deleted the instance In answer D, no other instance was created after I deleted the instance My observation is A is the correct Answer. A - Correct - It correctly solves the problem with only a single instance at one time B - Incorrect - Does not fit the requirement because AFTER the deletion of the instance, no other instance was created C - Incorrect - It creates another instance after the delete HOWEVER it 2 VM's could be created even if the target is exceeded D - Incorrect - Does not fit the requirement because AFTER the deletion of the instance, no other instance was created

   • ARun gcloud iam roles list. Review the output section.
   • BRun gcloud iam service-accounts list. Review the output section.
   • CNavigate to the project and then to the IAM section in the GCP Console. Review the members and roles.
   • DNavigate to the project and then to the Roles section in the GCP Console. Review the roles and status.

   Show answer

   Answer: C

   Explanation

   Correct answer is C as IAM section provides the list of both Members and Roles.Option A is wrong as it would provide information about the roles only.Option B is wrong as it would provide only the service accounts.Option D is wrong as it would provide information about the roles only.

   You need to create a new billing account and then link it with an existing Google Cloud Platform project. What should you do?

   • AVerify that you are Project Billing Manager for the GCP project. Update the existing project to link it to the existing billing account.
   • BVerify that you are Project Billing Manager for the GCP project. Create a new billing account and link the new billing account to the existing project.
   • CVerify that you are Billing Administrator for the billing account. Create a new project and link the new project to the existing billing account.
   • DVerify that you are Billing Administrator for the billing account. Update the existing project to link it to the existing billing account.

   Show answer

   Answer: B

   Explanation

   Project Billing Manager cannot create a billing account, there is nothing like Billing Administrator it is Billing Account Administrator. Both Project Billing Manager and Billing Account Administrator cannot create a billing account. A is the only answer that make sense. We have to assume the the billing acount is already created

   You have one project called proj-sa where you manage all your service accounts. You want to be able to use a service account from this project to take snapshots of VMs running in another project called proj-vm. What should you do?

   • ADownload the private key from the service account, and add it to each VMs custom metadata.
   • BDownload the private key from the service account, and add the private key to each VM's SSH keys.
   • CGrant the service account the IAM Role of Compute Storage Admin in the project called proj-vm.
   • DWhen creating the VMs, set the service account's API scope for Compute Engine to read/write.

   Show answer

   Answer: C

   Explanation

   C is the correct answer. It took me a while to figure it out because I didn't understand how service accounts work across project. This article made it clear for me. https://gtseres.medium.com/using-service-accounts-across-projects-in-gcp-cf9473fef8f0 You create the service account in proj-sa and take note of the service account email, then you go to proj-vm in IAM > ADD and add the service account's email as new member and give it the Compute Storage Admin role.

10. Question 210 · 325 in bank

    You need to grant access for three users so that they can view and edit table data on a Cloud Spanner instance. What should you do?

    • ARun gcloud iam roles describe roles/spanner.databaseUser. Add the users to the role.
    • BRun gcloud iam roles describe roles/spanner.databaseUser. Add the users to a new group. Add the group to the role.
    • CRun gcloud iam roles describe roles/spanner.viewer - -project my-project. Add the users to the role.
    • DRun gcloud iam roles describe roles/spanner.viewer - -project my-project. Add the users to a new group. Add the group to the role.

    Show answer

    Answer: B

    Explanation

    Answer C is incorrect because the `roles/spanner.viewer` role only allows read-only access to Spanner instances, whereas the question asks for users to be able to view and edit table data. Answer D is also incorrect for the same reason as answer C. The `roles/spanner.viewer` role does not provide the necessary permissions for editing table data. Therefore, answers A and B are the only options that provide the `roles/spanner.databaseUser` role, which includes the necessary permissions to view and edit table data on a Cloud Spanner instance. However, answer B is arguably better since it involves creating a new group and adding the users to that group, which can simplify the management of permissions in the future.
