NEW QUESTION # 118
Your organization has resources in two different VPCs, each in different Google Cloud projects, and requires connectivity between the resources in the two VPCs. You have already determined that there is no IP address overlap; however, one VPC uses privately used public IP (PUPI) ranges. You would like to enable connectivity between these resources by using a lower cost and higher performance method. What should you do?
- A. Create a VPC Network Peering connection between the two VPCs that allows the export and import of subnet routes with public IP addresses. Create the necessary ingress VPC firewall rules that target the specific resources by using IP ranges as the source filter.
- B. Create a VPC Network Peering connection between the two VPCs that allows the export and import of subnet routes with public IP addresses. Create the necessary ingress VPC firewall rules that target the specific resources by using network tags as the source filter.
- C. Create a VPC Network Peering connection between the two VPCs that allows the export and import of custom routes for public IP addresses. Create the necessary ingress VPC firewall rules that target the specific resources by using service accounts as the source filter.
- D. Create an HA VPN between the two VPCs that includes the PUPI ranges in the custom route advertisements of the Cloud Router. Create the necessary ingress VPC firewall rules that target the specific resources by using IP ranges as the source filter.
Answer: A
Explanation:
VPC Network Peering is the most cost-effective and high-performance method for connecting two VPCs. Since one VPC uses privately used public IP (PUPI) ranges, you need to configure peering to allow the export and import of subnet routes with public IP addresses. Firewall rules can be used to control traffic between the resources.
NEW QUESTION # 119
(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?)
- A. Create 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.
- B. Create 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.
- C. Create 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).
- D. Create 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.
Answer: C
Explanation:
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.

NEW QUESTION # 122
You are designing a Google Kubernetes Engine (GKE) cluster for your organization. The current cluster size is expected to host 10 nodes, with 20 Pods per node and 150 services. Because of the migration of new services over the next 2 years, there is a planned growth for 100 nodes, 200 Pods per node, and 1500 services. You want to use VPC-native clusters with alias IP ranges, while minimizing address consumption.
How should you design this topology?
- A. Create a subnet of size/25 with 2 secondary ranges of: /17 for Pods and /21 for Services. Create a VPC-native cluster and specify those ranges.
- B. Create a subnet of size/28 with 2 secondary ranges of: /24 for Pods and /24 for Services. Create a VPC-native cluster and specify those ranges. When the services are ready to be deployed, resize the subnets.
- C. Use gcloud container clusters create [CLUSTER NAME] to create a VPC-native cluster.
- D. Use gcloud container clusters create [CLUSTER NAME]--enable-ip-alias to create a VPC-native cluster.
Answer: A
Explanation:
The service range setting is permanent and cannot be changed. Please see https://stackoverflow.com/questions/60957040/how-to-increase-the-service-address-range-of-a-gke-cluster I think the correc tanswer is A since: Grow is expected to up to 100 nodes (that would be /25), then up to 200 pods per node (100 times 200 = 20000 so /17 is 32768), then 1500 services in a /21 (up to 2048)

NEW QUESTION # 129
Your company's Google Cloud-deployed, streaming application supports multiple languages. The application development team has asked you how they should support splitting audio and video traffic to different backend Google Cloud storage buckets. They want to use URL maps and minimize operational overhead.
They are currently using the following directory structure:
/fr/video
/en/video
/es/video
/../video
/fr/audio
/en/audio
/es/audio
/../audio
Which solution should you recommend?
- A. Rearrange the directory structure, create DNS hostname entries for video and audio and leverage a path rule such as /video/* and /audio/*.
- B. Leave the directory structure as-is, create a URL map and leverage a path rule such as /*/video and /*/ audio.
- C. Leave the directory structure as-is, create a URL map and leverage a path rule such as \/[a-z]{2}\/video and
\/[a-z]{2}\/audio. - D. Rearrange the directory structure, create a URL map and leverage a path rule such as /video/* and /audio
/*.
Answer: D
Explanation:
https://cloud.google.com/load-balancing/docs/url-map#configuring_url_maps Path matcher constraints Path matchers and path rules have the following constraints: A path rule can only include a wildcard character (*) after a forward slash character (/). For example, /videos/* and /videos/hd/* are valid for path rules, but /videos* and /videos/hd* are not. Path rules do not use regular expression or substring matching. For example, path rules for either /videos/hd or /videos/hd/* do not apply to a URL with the path /video/hd-abcd. However, a path rule for /video/* does apply to that path. https://cloud.google.com

NEW QUESTION # 130
Your organization has a subset of applications in multiple regions that require internet access. You need to control internet access from applications to URLs, including hostnames and paths. The compute instances that run these applications have an associated secure tag. What should you do?
- A. Deploy a Secure Web Proxy instance in each region. Apply a Secure Web Proxy policy to allow access from machines that match the secure tag to the URLs defined in a URL list.
- B. Deploy a Cloud NAT gateway. Use fully qualified domain name (FQDN) objects in the firewall policy rules to filter outgoing traffic to specific domains from machines that match the secure tag.
- C. Deploy a Cloud NAT gateway. Use fully qualified domain name (FQDN) objects in the firewall policy rules to filter outgoing traffic to specific domains from machines that match a service account.
- D. Deploy a single Secure Web Proxy instance with global access enabled. Apply a Secure Web Proxy policy to allow access from machines that match the secure tag to the URLs defined in a URL list.
Answer: D
Explanation:
To control internet access on a per-URL basis (including hostname and path), you should deploy Secure Web Proxy with global access enabled. The Secure Web Proxy will allow policy-based filtering of web traffic, allowing control over which URLs can be accessed based on the URL list defined in the policy. Unlike Cloud NAT, which does not support FQDN filtering, Secure Web Proxy is designed to provide such control, especially for scenarios with sensitive or controlled internet access requirements.
