Question 3

A company deploys a Kubernetes workload in GKE that needs to access Cloud Storage. They want to avoid managing service account keys. What is the recommended approach?

Accepted Answer

Use Workload Identity to map the Kubernetes service account to a GCP service account.. Workload Identity allows you to bind a Kubernetes service account to a GCP service account, so pods can authenticate using the GCP service account without managing keys.

Answer

Use the default Compute Engine service account on the node.

Answer

Store a service account key in a Kubernetes secret and mount it.

Answer

Use Cloud Key Management Service to encrypt the service account key.

Question 4

A company with multiple projects must ensure that no data can be exfiltrated from a specific project's Cloud Storage buckets to unauthorized locations outside the organization. They also need to allow access only from a corporate VPN IP range. Which configuration meets these requirements?

Accepted Answer

Configure a VPC Service Controls perimeter with an access level restricted to the corporate VPN IP range.. VPC Service Controls create a service perimeter around the project, preventing data exfiltration by default. Access levels (based on IP ranges) can be used to allow access only from the corporate VPN.

Answer

Set firewall rules to block all traffic except from the VPN.

Answer

Use IAM conditions to restrict access based on IP address.

Answer

Use Cloud Armor with IP whitelisting.

Question 5

Answer

Cloud Key Management Service (Cloud KMS)

Answer

Cloud Build

Answer

Artifact Registry

Question 9

A security engineer needs to allow a Compute Engine instance with the service account 'sa-prod@project.iam.gserviceaccount.com' to connect to a Cloud SQL instance over a private IP. The VPC has no firewall rules allowing this traffic. What is the MOST secure way to grant access?

Accepted Answer

Add a firewall rule with source service account 'sa-prod@project.iam.gserviceaccount.com' and target service account 'cloud-sql-sa@project.iam.gserviceaccount.com'. Firewall rules can target service accounts directly, allowing fine-grained access without relying on network tags. This avoids managing tags and reduces attack surface.

Answer

Grant the IAM role 'cloudsql.client' to the service account 'sa-prod@project.iam.gserviceaccount.com'

Answer

Add a firewall rule with source tag 'prod' and target tag 'cloud-sql'

Answer

Create a VPC peering connection between the Compute Engine VPC and the Cloud SQL VPC

Question 10

A company uses Cloud Key Management Service (Cloud KMS) with a customer-managed encryption key (CMEK) to encrypt data in BigQuery. They want to ensure the key can only be used by the BigQuery service account in the 'us-central1' region. Which IAM condition should be added to the key's IAM policy?

Accepted Answer

resource.name.startsWith('projects/_/locations/us-central1') && request.auth.principalSet == 'serviceAccount:bq-<project-number>@bigquery-encryption.iam.gserviceaccount.com'. IAM conditions allow restricting access based on attributes like region and service account. The condition must check the 'destination_service' for BigQuery and the 'region' for us-central1.

Answer

resource.name.startsWith('projects/_/locations/us-central1') && request.auth.principal == 'bigquery@system.gserviceaccount.com'

Answer

resource.name.startsWith('projects/_/locations/global') && request.auth.principal == 'bigquery@system.gserviceaccount.com'

Answer

resource.service == 'bigquery.googleapis.com' && resource.location == 'us-central1'

Question 11

Which Google Cloud service allows organizations to define perimeters that protect resources and data from exfiltration to other VPCs or networks?

Accepted Answer

VPC Service Controls. VPC Service Controls allow you to define service perimeters that restrict access to managed services from outside the perimeter, preventing data exfiltration.

Answer

Private Service Connect

Answer

Identity-Aware Proxy (IAP)

Answer

Cloud Armor

Question 12

A company is migrating an on-premises application to Google Cloud. The application requires access to a legacy database that can only be reached from a specific on-premises IP address. The company has established a Cloud VPN tunnel. What is the MOST secure way to ensure that only the migrated application's Compute Engine instances can initiate connections to the on-premises database?

Accepted Answer

Create a firewall egress rule with destination IP range of the on-premises database and source service account of the application instances. Using firewall rules with target service accounts allows you to control egress traffic based on the identity of the source instances, which is more secure than using tags or IP ranges.

Answer

Create a Cloud NAT and assign the application instances a static IP, then allow that IP in the on-premises firewall

Answer

Create a firewall egress rule with destination IP range of the on-premises database and source tags 'db-access'

Answer

Use VPC Service Controls to create a perimeter around the application VPC

Question 13

An organization needs to store API keys and database passwords securely in Google Cloud. They want to automatically rotate secrets every 30 days. Which service should they use?
