   A team of data scientists infrequently needs to use a Google Kubernetes Engine (GKE) cluster that you manage. They require GPUs for some long-running, non- restartable jobs. You want to minimize cost. What should you do?

   • AEnable node auto-provisioning on the GKE cluster.
   • BCreate a VerticalPodAutscaler for those workloads.
   • CCreate a node pool with preemptible VMs and GPUs attached to those VMs.
   • DCreate a node pool of instances with GPUs, and enable autoscaling on this node pool with a minimum size of 1.

   Show answer

   Answer: A

   Explanation

   Incorrect options are B. VerticalPodAutscaler scales PODS based on the app you deploy. For handle infrequently GPU access, you need infrequently GPU nodes VerticalAutscaler Pod deployed on a non GPU node it useless, [We cant have the node always have GPU for infrequent requests] C. Preemptible VMs cant last long D. For infrequent access, you don't want to have a permanent homogenous cluster. The correct option is "A" auto-provisioning = Attaches and deletes node pools to cluster based on the requirements. Hence creating a GPU node pool, and auto-scaling would be better https://cloud.google.com/kubernetes-engine/docs/how-to/node-auto-provisioning

4. Question 14 · 325 in bank

   You have successfully created a development environment in a project for an application. This application uses Compute Engine and Cloud SQL. Now you need to create a production environment for this application. The security team has forbidden the existence of network routes between these 2 environments and has asked you to follow Google-recommended practices. What should you do?

   • ACreate a new project, enable the Compute Engine and Cloud SQL APIs in that project, and replicate the setup you have created in the development environment.
   • BCreate a new production subnet in the existing VPC and a new production Cloud SQL instance in your existing project, and deploy your application using those resources.
   • CCreate a new project, modify your existing VPC to be a Shared VPC, share that VPC with your new project, and replicate the setup you have in the development environment in that new project in the Shared VPC.
   • DAsk the security team to grant you the Project Editor role in an existing production project used by another division of your company. Once they grant you that role, replicate the setup you have in the development environment in that project.

   Show answer

   Answer: A

   Explanation

   A - correct. Best practice is to create a new project for each environment, such as production and testing. There are no routes between VPCs in these projects by default, so that satisfies the requirement by the security team. B. Nope. not best practice and allows communication. C. While this is best practice to create a new project for a different environment, it explicitly breaks the security team's rule of having no path between environments by nature of the shared VPC. The shared VPC allows entities in both VPCs to communicate as if they were in the same VPC. That's definitely wrong. D. One - not best practice to replicate in the setup in that project. Two - why do they suddenly need the project editor rule? Just a bad answer. Wrong.

5. Question 15 · 325 in bank

   Your management has asked an external auditor to review all the resources in a specific project. The security team has enabled the Organization Policy called Domain Restricted Sharing on the organization node by specifying only your Cloud Identity domain. You want the auditor to only be able to view, but not modify, the resources in that project. What should you do?

   • AAsk the auditor for their Google account, and give them the Viewer role on the project.
   • BAsk the auditor for their Google account, and give them the Security Reviewer role on the project.
   • CCreate a temporary account for the auditor in Cloud Identity, and give that account the Viewer role on the project.
   • DCreate a temporary account for the auditor in Cloud Identity, and give that account the Security Reviewer role on the project.

   Show answer

   Answer: C

   Explanation

   Correct Answer is (C): roles/viewer Read access to all resources. Get and list access for all resources. Using primitive roles The following table lists the primitive roles that you can grant to access a project, the description of what the role does, and the permissions bundled within that role. Avoid using primitive roles except when absolutely necessary. These roles are very powerful, and include a large number of permissions across all Google Cloud services. For more details on when you should use primitive roles, see the Identity and Access Management FAQ. IAM predefined roles are much more granular, and allow you to carefully manage the set of permissions that your users have access to. See Understanding Roles for a list of roles that can be granted at the project level. Creating custom roles can further increase the control you have over user permissions. https://cloud.google.com/resource-manager/docs/access-control-proj#using_primitive_roles

6. Question 16 · 325 in bank

   You have a workload running on Compute Engine that is critical to your business. You want to ensure that the data on the boot disk of this workload is backed up regularly. You need to be able to restore a backup as quickly as possible in case of disaster. You also want older backups to be cleaned automatically to save on cost. You want to follow Google-recommended practices. What should you do?

   • ACreate a Cloud Function to create an instance template.
   • BCreate a snapshot schedule for the disk using the desired interval.
   • CCreate a cron job to create a new disk from the disk using gcloud.
   • DCreate a Cloud Task to create an image and export it to Cloud Storage.

   Show answer

   Answer: B

   Explanation

   Correct Answer (B): Best practices for persistent disk snapshots You can create persistent disk snapshots at any time, but you can create snapshots more quickly and with greater reliability if you use the following best practices. Creating frequent snapshots efficiently Use snapshots to manage your data efficiently. Create a snapshot of your data on a regular schedule to minimize data loss due to unexpected failure. Improve performance by eliminating excessive snapshot downloads and by creating an image and reusing it. Set your snapshot schedule to off-peak hours to reduce snapshot time. Snapshot frequency limits Creating snapshots from persistent disks You can snapshot your disks at most once every 10 minutes. If you want to issue a burst of requests to snapshot your disks, you can issue at most 6 requests in 60 minutes. If the limit is exceeded, the operation fails and returns the following error: https://cloud.google.com/compute/docs/disks/snapshot-best-practices

7. Question 17 · 325 in bank

   You need to assign a Cloud Identity and Access Management (Cloud IAM) role to an external auditor. The auditor needs to have permissions to review your Google Cloud Platform (GCP) Audit Logs and also to review your Data Access logs. What should you do?

   • AAssign the auditor the IAM role roles/logging.privateLogViewer. Perform the export of logs to Cloud Storage.
   • BAssign the auditor the IAM role roles/logging.privateLogViewer. Direct the auditor to also review the logs for changes to Cloud IAM policy.
   • CAssign the auditor's IAM user to a custom role that has logging.privateLogEntries.list permission. Perform the export of logs to Cloud Storage.
   • DAssign the auditor's IAM user to a custom role that has logging.privateLogEntries.list permission. Direct the auditor to also review the logs for changes to Cloud IAM policy.

   Show answer

   Answer: B

   Explanation

   Correct Answer is (B): Background Google Cloud provides Cloud Audit Logs, which is an integral part of Cloud Logging. It consists of two log streams for each project: Admin Activity and Data Access. Admin Activity logs contain log entries for API calls or other administrative actions that modify the configuration or metadata of resources. Admin Activity logs are always enabled. There is no charge for your Admin Activity audit logs. Data Access logs record API calls that create, modify, or read user-provided data. Data Access audit logs are disabled by default because they can be large. logging.viewer: The logging.viewer role gives the security admin team the ability to view the Admin Activity logs. logging.privateLogViewer : The logging.privateLogViewer role gives the ability to view the Data Access logs.

8. Question 18 · 325 in bank

   You are managing several Google Cloud Platform (GCP) projects and need access to all logs for the past 60 days. You want to be able to explore and quickly analyze the log contents. You want to follow Google-recommended practices to obtain the combined logs for all projects. What should you do?

   • ANavigate to Stackdriver Logging and select resource.labels.project_id="*"
   • BCreate a Stackdriver Logging Export with a Sink destination to a BigQuery dataset. Configure the table expiration to 60 days.
   • CCreate a Stackdriver Logging Export with a Sink destination to Cloud Storage. Create a lifecycle rule to delete objects after 60 days.
   • DConfigure a Cloud Scheduler job to read from Stackdriver and store the logs in BigQuery. Configure the table expiration to 60 days.

   Show answer

   Answer: B

   Explanation

   I believe B is the answer. All that matters in this scenario is the logs for the past 60 days. We can use BigQuery to analyze contents so C is incorrect. We need to configure a BQ as the sink for the logs export so we can query and analyze log data in the future. Therefore D is incorrect. https://cloud.google.com/logging/docs/audit/best-practices#export-best-practices Since we only care about the logs within 60 days, we can set the expiration time to 60 to retain only the logs within that time frame. Once data is beyond 60 days old, it wouldn't be included in future analyzations. https://cloud.google.com/bigquery/docs/managing-tables#updating_a_tables_expiration_time

   Answer: A

   Explanation

   I have to go with A as the correct answer according to support.google.com URL: https://support.google.com/googleapi/answer/6251787?hl=en# What stands out at me is the paragraph "Shutting down a project stops all billing and traffic serving, shuts down any Google Cloud Platform App Engine applications, and terminates all Compute Engine instances. All project data associated with Google Cloud and Google APIs services becomes inaccessible."

10. Question 20 · 325 in bank

    You are configuring service accounts for an application that spans multiple projects. Virtual machines (VMs) running in the web-applications project need access to BigQuery datasets in crm-databases-proj. You want to follow Google-recommended practices to give access to the service account in the web-applications project. What should you do?

    • AGive ג€project ownerג€ for web-applications appropriate roles to crm-databases-proj.
    • BGive ג€project ownerג€ role to crm-databases-proj and the web-applications project.
    • CGive ג€project ownerג€ role to crm-databases-proj and bigquery.dataViewer role to web-applications.
    • DGive bigquery.dataViewer role to crm-databases-proj and appropriate roles to web-applications.

    Show answer

    Answer: D

    Explanation

    It is D because you're right, the question doesn't specify any specific kind of access, however, we need to follow the principle of least-privilege. Hence, we can only assume that read-only access is needed. bigquery.dataViewer should be assigned to the group of analysts in the crm-databases-proj project. https://cloud.google.com/bigquery/docs/access-control-examples#read_access_to_data_in_a_different_project
