Question No. 1

You created a VPC network named Retail in auto mode. You want to create a VPC network named Distribution and peer it with the Retail VPC.

How should you configure the Distribution VPC?

ACreate the Distribution VPC in auto mode. Peer both the VPCs via network peering.

BCreate the Distribution VPC in custom mode. Use the CIDR range 10.0.0.0/9. Create the necessary subnets, and then peer them via network peering.

CCreate the Distribution VPC in custom mode. Use the CIDR range 10.128.0.0/9. Create the necessary subnets, and then peer them via network peering.

DRename the default VPC as 'Distribution' and peer it via network peering.

Question No. 2

(You are deploying an application to Google Kubernetes Engine (GKE). The application needs to make API calls to a private Cloud Storage bucket. You need to configure your application Pods to authenticate to the Cloud Storage API, but your organization policy prevents the usage of service account keys. You want to follow Google-recommended practices. What should you do?)

ACreate the GKE cluster and deploy the application. Request a security exception to create a Google service account key. Set the constraints/iam.serviceAccountKeyExpiryHours organization policy to 8 hours.

BCreate the GKE cluster and deploy the application. Request a security exception to create a Google service account key. Set the constraints/iam.serviceAccountKeyExpiryHours organization policy to 24 hours.

CCreate the GKE cluster with Workload Identity Federation. Configure the default node service account to access the bucket. Deploy the application into the cluster so the application can use the node service account permissions. Use Identity and Access Management (IAM) to grant the service account access to the bucket.

DCreate the GKE cluster with Workload Identity Federation. Create a Google service account and a Kubernetes ServiceAccount, and configure both service accounts to use Workload Identity Federation. Attach the Kubernetes ServiceAccount to the application Pods and configure the Google service account to access the bucket with Identity and Access Management (IAM).

Show Answer

Correct Answer: D

Create a Google Service Account: You create a dedicated Google service account specifically for your application's interaction with the private Cloud Storage bucket. This allows you to grant precise IAM permissions to this service account on the bucket (e.g., roles/storage.objectViewer or roles/storage.objectCreator).

Create a Kubernetes ServiceAccount: You create a Kubernetes ServiceAccount within your GKE cluster. This is the identity that your application Pods will assume within the cluster.

Configure Workload Identity Federation: You establish a trust relationship between the Kubernetes ServiceAccount and the Google service account using Workload Identity Federation. This involves configuring IAM policies that allow the Kubernetes ServiceAccount to impersonate the Google service account.

Annotate Pods with the Kubernetes ServiceAccount: You associate the created Kubernetes ServiceAccount with your application Pods. When the application in these Pods makes a call to the Cloud Storage API, the Workload Identity agent running on the GKE nodes automatically exchanges the Kubernetes ServiceAccount token for a short-lived Google Cloud access token for the associated Google service account.

This approach offers several security advantages and aligns with Google's recommended practices:

Principle of Least Privilege: The Google service account is granted only the necessary permissions to access the specific Cloud Storage bucket.

No Service Account Keys to Manage: You avoid the security risks associated with creating, storing, and rotating service account keys.

Auditable Authentication: All API calls are attributed to the specific Google service account, providing better auditability.

Simplified Management: Workload Identity Federation automates the credential management process for your application.

Google Cloud Documentation References:

Workload Identity: https://cloud.google.com/kubernetes-engine/docs/how-to/workload-identity 1 - This is the primary documentation explaining how to use Workload Identity to allow applications in GKE to access Google Cloud services securely without using service account keys.

Question No. 3

Your organization wants to set up hybrid connectivity with VLAN attachments that terminate in a single Cloud Router with 99.9% uptime. You need to create a network design for your on-premises router that meets those requirements and has an active/passive configuration that uses only one VLAN attachment at a time. What should you do?

ACreate a design that uses a BGP multi-exit discriminator (MED) attribute to influence the egress path from Google Cloud to the on-premises environment.

BCreate a design that uses the as_path BGP attribute to influence the egress path from Google Cloud to the on-premises environment.

CCreate a design that uses an equal-cost multipath (ECMP) with flow-based hashing on your on-premises devices.

DCreate a design that uses the local_pref BGP attribute to influence the egress path from Google Cloud to the on-premises environment.

Show Answer

Correct Answer: A

The BGP multi-exit discriminator (MED) attribute is used in BGP configurations to influence the choice of path in an active/passive setup by prioritizing one path over another for egress traffic. This is ideal for a design that uses only one VLAN attachment at a time.

Question No. 4

You are troubleshooting connectivity issues between Google Cloud and a public SaaS provider. Connectivity between the two environments is through the public internet. Your users are reporting intermittent connection errors when using TCP to connect; however, ICMP tests show no failures. According to users, errors occur around the same time every day. You want to troubleshoot and gather information by using Google Cloud tools that are most likely to provide insights into what is occurring within Google Cloud. What should you do?

AEnable the Firewall Insights API. Set the deny rule insights observation period to one day. Review the insights to assure there are no firewall rules denying traffic.

BEnable and review Cloud Logging on your Cloud NAT gateway. Look for logs with errors matching the destination IP address of the public SaaS provider.

CCreate a Connectivity Test by using TCP, the source IP address of your test VM, and the destination IP address of the public SaaS provider. Review the live data plane analysis and take the next steps based on the test results.

DEnable and review Cloud Logging for Cloud Armor. Look for logs with errors matching the destination IP address of the public SaaS provider.

Show Answer

Correct Answer: C

Creating a Connectivity Test using TCP in Network Intelligence Center allows you to simulate the connection to the public SaaS provider and receive real-time data plane analysis. This will help determine whether there are any issues with the network path for the specific TCP connection.

Question No. 5

You recently deployed Cloud VPN to connect your on-premises data canter to Google Cloud. You need to monitor the usage of this VPN and set up alerts in case traffic exceeds the maximum allowed. You need to be able to quickly decide whether to add extra links or move to a Dedicated Interconnect. What should you do?

AIn the Network Intelligence Canter, check for the number of packet drops on the VPN.

BIn the Google Cloud Console, use Monitoring Query Language to create a custom alert for bandwidth utilization.

CIn the Monitoring section of the Google Cloud Console, use the Dashboard section to select a default dashboard for VPN usage.

DIn the VPN section of the Google Cloud Console, select the VPN under hybrid connectivity, and then select monitoring to display utilization on the dashboard.
