Google Updated Professional-Cloud-Security-Engineer Exam Questions and Answers by aliyah

The problem requires automating user provisioning to a Cloud Identity security group using a service account, adhering to Google-recommended practices and the principle of least privilege.

Cloud Identity Groups and Google Workspace: Cloud Identity groups are managed as part of Google Workspace. To programmatically manage Google Workspace resources (like groups), you typically use the Admin SDK APIs.

Domain-Wide Delegation: Service accounts cannot directly authenticate to Google Workspace APIs using IAM roles. Instead, they require "domain-wide delegation" to impersonate a user with the necessary administrative privileges within Google Workspace. This allows a service account to access user data or perform administrative tasks across the domain. The correct scope for managing groups is https://www.googleapis.com/auth/admin.directory.group.Extract Reference: "To allow a service account to access user data on behalf of users in a Google Workspace domain, you must delegate domain-wide authority to your service account." (Google Cloud documentation: https://developers.google.com/identity/protocols/oauth2/service-account#delegating)

Extract Reference (Admin SDK Scopes): The https://www.googleapis.com/auth/admin.directory.group scope is explicitly listed for "View and manage all groups on the domain." (Google Workspace Admin SDK documentation: https://developers.google.com/admin-sdk/directory/v1/scopes)

Application Default Credentials (ADC) with Resource-Attached Service Account: Google-recommended practices strongly advise against using service account keys directly for authentication when running on Google Cloud infrastructure. Instead, it's recommended to use Application Default Credentials (ADC) with a service account attached to the resource (e.g., a Compute Engine VM, Cloud Run service, or Cloud Functions). This method manages credentials automatically and securely, reducing the risk associated with managing and rotating keys.Extract Reference: "For most Google Cloud services, Application Default Credentials (ADC) is the recommended way to authenticate." and "When running code in a Google Cloud environment, such as Compute Engine, Cloud Run, or Cloud Functions, use the built-in service account to authenticate automatically with ADC. This is the most secure approach, as you don't need to manually create or manage service account keys." (Google Cloud documentation: https://cloud.google.com/docs/authentication/production)

Options C and D are incorrect because granting an IAM role like "Groups Editor" in Google Cloud does not enable a service account to manage Google Workspace (Cloud Identity) group memberships; domain-wide delegation is required for that. Option A uses a service account key, which is less secure than ADC with a resource-attached service account according to Google's recommendations.

Therefore, option B is the most aligned with Google's recommended practices for securely automating group provisioning using a service account and domain-wide delegation.

The Standard Tier network only provides regional load balancing, while the Premium Tier supports global load balancing with a single anycast IP address. To distribute requests across multiple regions, you need to use the Premium Tier and update the load balancer configuration accordingly.

Steps:

Upgrade to Premium Tier: Update the load balancer to use the Premium Tier network in the Google Cloud Console.

Add New Instance Group: Add the instance group in the new region (us-east-2) to the backend configuration of the existing load balancer.

Verify Configuration: Ensure that the frontend configuration of the load balancer uses a single external IP address for global distribution.

To ensure compliance with the Payment Card Industry Data Security Standard (PCI DSS) at the infrastructure-as-a-service (IaaS) level within Google Cloud, it's essential to have continuous monitoring and assessment tools that can detect deviations from compliance requirements.​

Option A: Creating data profiles and configuring Data Discovery jobs in Google Cloud Sensitive Data Protection focuses on identifying and analyzing sensitive data but does not directly address infrastructure compliance monitoring.​

Option B: Downloading the latest PCI DSS report from the Compliance Reports Manager provides a static compliance report but does not offer real-time detection of deviations within your specific environment.​

Option C: Utilizing Assured Workloads helps in creating environments that meet specific compliance requirements, but migrating existing projects into such folders does not actively detect deviations; it primarily ensures that new workloads comply with predefined policies.​

Option D: Activating Security Command Center (SCC) Premium and leveraging its Compliance Monitoring capabilities allows for continuous assessment of your Google Cloud environment against PCI DSS requirements. SCC can identify misconfigurations, vulnerabilities, and compliance violations in real-time, providing actionable insights to address any issues promptly.​

Therefore, Option D is the most effective approach to detect deviations at the IaaS level in preparation for a PCI DSS audit.​

Objective: Ensure that a Cloud Storage bucket in Project A can only be readable from Project B and prevent data access or copying to Cloud Storage buckets outside the network, even with correct credentials.

Solution: Use VPC Service Controls to create a security perimeter.

Steps:

Step 1: Open the Google Cloud Console.

Step 2: Navigate to the VPC Service Controls page.

Step 3: Create a new service perimeter.

Step 4: Add Project A and Project B to the service perimeter.

Step 5: Include Cloud Storage service in the perimeter configuration.

Step 6: Define access levels to ensure that only resources within the perimeter can access the Cloud Storage bucket.

By setting up a VPC Service Controls perimeter, you can enforce security boundaries that restrict data access and movement to within defined projects, providing an extra layer of protection beyond IAM permissions.
