Your organization needs to grant users access to query datasets in BigQuery but prevent them from accidentally deleting the datasets. You want a solution that follows Google-recommended practices. What should you do?

• Add users to roles/bigquery user role only, instead of roles/bigquery dataOwner.

• Add users to roles/bigquery dataEditor role only, instead of roles/bigquery dataOwner.

• Create a custom role by removing delete permissions, and add users to that role only.

• Create a custom role by removing delete permissions. Add users to the group, and then add the group to the custom role.

Answer explanation

User Role will grant them permission to CREATE new datasets and the datasets created by the role will make the user OWNER of those datasets thereby giving them permission to delete.

You have a developer laptop with the Cloud SDK installed on Ubuntu. The Cloud SDK was installed from the Google Cloud Ubuntu package repository. You want to test your application locally on your laptop with Cloud Datastore. What should you do?

• Export Cloud Datastore data using gcloud datastore export.

• Create a Cloud Datastore index using gcloud datastore indexes create.

• Install the google-cloud-sdk-datastore-emulator component using the apt get install command.

• Install the cloud-datastore-emulator component using the gcloud components install command.

Answer explanation

Controversial, could be using gcloud or apt-get

Community: gcloud
To test your application locally on your laptop with Cloud Datastore, you should install the google-cloud-sdk-datastore-emulator component using the apt get install command. This component provides a local development server that can emulate the Cloud Datastore service. You can then use the Cloud Datastore client libraries to interact with the emulator as if it were the actual Cloud Datastore service. https://cloud.google.com/sdk/docs/downloads-apt-get

Your company set up a complex organizational structure on Google Cloud. The structure includes hundreds of folders and projects. Only a few team members should be able to view the hierarchical structure. You need to assign minimum permissions to these team members, and you want to follow Google-recommended practices. What should you do?

• Add the users to roles/browser role.

• Add the users to roles/iam.roleViewer role.

• Add the users to a group, and add this group to roles/browser.

• Add the users to a group, and add this group to roles/iam.roleViewer role

Answer explanation

We need to apply the GCP Best practices. The roles/browser Browser Read access to browse the hierarchy for a project, including the folder, organization, and IAM policy. This role doesn't include permission to view resources in the project. https://cloud.google.com/iam/docs/understanding-roles

Your company has a single sign-on (SSO) identity provider that supports Security Assertion Markup Language (SAML) integration with service providers. Your company has users in Cloud Identity. You would like users to authenticate using your company's SSO provider. What should you do?

• In Cloud Identity, set up SSO with Google as an identity provider to access custom SAML apps.

• In Cloud Identity, set up SSO with a third-party identity provider with Google as a service provider.

• Obtain OAuth 2.0 credentials, configure the user consent screen, and set up OAuth 2.0 for Mobile & Desktop Apps.

• Obtain OAuth 2.0 credentials, configure the user consent screen, and set up OAuth 2.0 for Web Server Applications.

Your organization has a dedicated person who creates and manages all service accounts for Google Cloud projects. You need to assign this person the minimum role for projects. What should you do?

• Add the user to roles/iam.roleAdmin role.

• Add the user to roles/iam.securityAdmin role.

• Add the user to roles/iam.serviceAccountUser role.

• Add the user to roles/iam.serviceAccountAdmin role.

Answer explanation

Service Account User (roles/iam.serviceAccountUser): Includes permissions to list service accounts, get details about a service account, and impersonate a service account. Service Account Admin (roles/iam.serviceAccountAdmin): Includes permissions to list service accounts and get details about a service account. Also includes permissions to create, update, and delete service accounts, and to view or change the IAM policy on a service account.

You are building an archival solution for your data warehouse and have selected Cloud Storage to archive your data. Your users need to be able to access this archived data once a quarter for some regulatory requirements. You want to select a cost-efficient option. Which storage option should you use?

• Cold Storage

• Nearline Storage

• Regional Storage

• Multi-Regional Storage

Answer explanation

Nearline storage is a low-cost, highly durable storage service for storing infrequently accessed data. Nearline storage is a better choice than Standard storage in scenarios where slightly lower availability, a 30-day minimum storage duration, and costs for data access are acceptable trade-offs for lowered at-rest storage costs. (A should be suitable, but it appears there's no a "Cold" storage, or might be related to a typo with "Coldline"

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

• Enable node auto-provisioning on the GKE cluster.

• Create a VerticalPodAutscaler for those workloads.

• Create a node pool with preemptible VMs and GPUs attached to those VMs.

• Create a node pool of instances with GPUs, and enable autoscaling on this node pool with a minimum size of 1.

Answer explanation

Creating an autoscaling GPU node pool: To take the best, most cost-effective advantage of GPUs on GKE, and to take advantage of cluster autoscaling, we recommend creating separate GPU node pools in your clusters. https://cloud.google.com/kubernetes-engine/docs/how-to/gpus#gpu_pool

Your organization has user identities in Active Directory. Your organization wants to use Active Directory as their source of truth for identities. Your organization wants to have full control over the Google accounts used by employees for all Google services, including your Google Cloud Platform (GCP) organization. What should you do?

• Use Google Cloud Directory Sync (GCDS) to synchronize users into Cloud Identity.

• Use the cloud Identity APIs and write a script to synchronize users to Cloud Identity.

• Export users from Active Directory as a CSV and import them to Cloud Identity via the Admin Console.

• Ask each employee to create a Google account using self signup. Require that each employee use their company email address and password.

Answer explanation

Google Cloud Directory Sync enables administrators to synchronize users, groups and other data from an Active Directory/LDAP service to their Google Cloud domain directory https://tools.google.com/dlpage/dirsync/

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?

• Create 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.

• Create 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.

• Create 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.

• Ask 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.

Answer explanation

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.

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?

• Ask the auditor for their Google account, and give them the Viewer role on the project.

• Ask the auditor for their Google account, and give them the Security Reviewer role on the project.

• Create a temporary account for the auditor in Cloud Identity, and give that account the Viewer role on the project.

• Create a temporary account for the auditor in Cloud Identity, and give that account the Security Reviewer role on the project.

Answer explanation

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
