NEW QUESTION # 65
(You are managing the security configuration of your company's Google Cloud organization. The Operations team needs specific permissions on both a Google Kubernetes Engine (GKE) cluster and a Cloud SQL instance. Two predefined Identity and Access Management (IAM) roles exist that contain a subset of the permissions needed by the team. You need to configure the necessary IAM permissions for this team while following Google-recommended practices. What should you do?)
- A. Grant the team the two predefined IAM roles.
- B. Grant the team the IAM roles of Kubernetes Engine Admin and Cloud SQL Admin.
- C. Create a custom IAM role that combines the permissions from the two relevant predefined roles.
- D. Create a custom IAM role that includes only the required permissions from the predefined roles.
Answer: D
Explanation:
Comprehensive and Detailed In Depth Explanation:
Granting more permissions than necessary violates the principle of least privilege, a fundamental security best practice. While option A grants the necessary permissions (as subsets exist in two predefined roles), it might also grant more permissions than the Operations team strictly requires for their tasks on GKE and Cloud SQL.
Option D is too broad; 'Admin' roles grant extensive permissions that likely exceed the specific needs.
Google Cloud's best practices strongly recommend adhering to the principle of least privilege. Creating a custom role allows you to precisely define the set of permissions the Operations team needs for their specific tasks on the GKE cluster and the Cloud SQL instance, without granting any unnecessary permissions. This minimizes the potential blast radius in case of accidental or malicious actions.

NEW QUESTION # 66
You are troubleshooting an application in your organization's Google Cloud network that is not functioning as expected. You suspect that packets are getting lost somewhere. The application sends packets intermittently at a low volume from a Compute Engine VM to a destination on your on-premises network through a pair of Cloud Interconnect VLAN attachments. You validated that the Cloud Next Generation Firewall (Cloud NGFW) rules do not have any deny statements blocking egress traffic, and you do not have any explicit allow rules. Following Google-recommended practices, you need to analyze the flow to see if packets are being sent correctly out of the VM to isolate the issue. What should you do?
- A. Enable Firewall Rules Logging on your firewall rules and review the logs.
- B. Create a packet mirroring policy that is configured with your VM as the source and destined to a collector. Analyze the packet captures.
- C. Verify the network/attachment/egress_dropped_packet.s_count Cloud Interconnect VLAN attachment metric.
- D. Enable VPC Flow Logs on the subnet that the VM is deployed in with sample_rate = 1.0, and run a query in Logs Explorer to analyze the packet flow.
Answer: D
Explanation:
Explanation: Enabling VPC Flow Logs with sample_rate = 1.0 on the VM's subnet will give detailed information about network traffic flowing to and from your VM. You can then query this data in Logs Explorer to check whether packets are leaving the VM and reaching the intended destination. This is a recommended practice for troubleshooting such network issues.
NEW QUESTION # 67
Your organization recently re-architected your cloud environment to use Network Connectivity Center. However, an error occurred when you tried to add a new VPC named vpc-dev as a spoke. The error indicated that there was an issue with an existing spoke and the IP space of a VPC named vpc-pre-prod. You must complete the migration quickly and efficiently. What should you do?
- A. Exclude the conflicting IP range by using the --exclude-export-ranges flag in the hub when attaching the VPC spoke for vpc-dev.
- B. Remove the conflicting VPC spoke for vpc-pre-prod from the set of VPC spokes in Network Connectivity Center. Add the VPC spoke for vpc-dev. Add the previously removed vpc-pre-prod as a VPC spoke.
- C. Exclude the conflicting IP range by using the --exclude-export-ranges flag when creating the VPC spoke for vpc-dev.
- D. Delete the VMs associated with the conflicting subnets, then delete the conflicting subnets in vpc-dev. Recreate the subnets with a new IP range and redeploy the previously deleted VMs in the new subnets. Add the VPC spoke for vpc-dev.
Answer: B
Explanation:
The most efficient way to resolve the conflict is to temporarily remove the conflicting vpc-pre-prod spoke, add the vpc-dev spoke, and then re-add vpc-pre-prod. This ensures that the migration happens quickly without the need to change IP ranges or delete resources.
NEW QUESTION # 68
Your company has 10 separate Virtual Private Cloud (VPC) networks, with one VPC per project in a single region in Google Cloud. Your security team requires each VPC network to have private connectivity to the main on-premises location via a Partner Interconnect connection in the same region. To optimize cost and operations, the same connectivity must be shared with all projects. You must ensure that all traffic between different projects, on-premises locations, and the internet can be inspected using the same third-party appliances. What should you do?
- A. Configure the third-party appliances with multiple interfaces, with each interface connected to a separate VPC network. Create separate VPC networks for on- premises and internet connectivity.
Create the relevant routes on the third-party appliances and VPC networks. - B. Consolidate all existing projects' subnetworks into a single VPC. Create separate VPC networks for on- premises and internet connectivity. Configure the third-party appliances with multiple interfaces, with each interface connected to a separate VPC network. Create the relevant routes on the third-party appliances and VPC networks.
- C. Configure the third-party appliances with multiple interfaces and specific Partner Interconnect VLAN attachments per project. Create the relevant routes on the third-party appliances and VPC networks.
- D. Configure the third-party appliances with multiple interfaces. Create a hub VPC network for all projects, and create separate VPC networks for on-premises and internet connectivity. Create the relevant routes on the third-party appliances and VPC networks. Use VPC Network Peering to connect all projects' VPC networks to the hub VPC. Export custom routes from the hub VPC and import on all projects' VPC networks.
Answer: D
NEW QUESTION # 69
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?
- A. Create a design that uses the as_path BGP attribute to influence the egress path from Google Cloud to the on-premises environment.
- B. Create a design that uses the local_pref BGP attribute to influence the egress path from Google Cloud to the on-premises environment.
- C. Create a design that uses a BGP multi-exit discriminator (MED) attribute to influence the egress path from Google Cloud to the on-premises environment.
- D. Create a design that uses an equal-cost multipath (ECMP) with flow-based hashing on your on-premises devices.
Answer: C
Explanation:
Explanation: 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.

NEW QUESTION # 71
You ate planning to use Terraform to deploy the Google Cloud infrastructure for your company, The design must meet the following requirements
* Each Google Cloud project must represent an Internal project that your team Will work on
* After an Internal project is finished, the infrastructure must be deleted
* Each Internal project must have Its own Google Cloud project owner to manage the Google Cloud resources.
* You have 10-100 projects deployed at a time
While you are writing the Terraform code, you need to ensure that the deployment is simple and the code is reusable With centralized management What should you do?
- A. Create a Shared VPC and service project for each internal project
- B. Create a Single project and additional VPCs for each internal project
- C. Create a Single Shared VPC and attach each Google Cloud project as a service project
- D. Create a Single project and Single VPC for each internal project
Answer: A
Explanation:
The correct answer is D because it meets the following requirements:
Each internal project has its own Google Cloud project, which can be easily created and deleted by Terraform using the google_project resource1.
Each internal project has its own Google Cloud project owner, which can be assigned by Terraform using the google_project_iam_member resource1.
The deployment is simple and the code is reusable with centralized management, because the Shared VPC allows you to connect multiple service projects to a single host project that contains the network resources2. This way, you can use Terraform modules to create and manage the network resources in the host project, and then reference them in the service projects3.
Option A is incorrect because it does not create separate Google Cloud projects for each internal project, which makes it harder to delete the infrastructure and assign project owners. Option B is incorrect because it does not create separate Google Cloud projects for each internal project, and also because it attaches the service projects to a Shared VPC, which is not recommended for short-lived projects2. Option C is incorrect because it does not use a Shared VPC, which means that each internal project has to create and manage its own network resources, which increases complexity and reduces reusability.

- A. Configure a global external Application Load Balancer with weighted traffic splitting.
- B. Configure two separate global external Application Load Balancers, and use Cloud DNS geolocation routing policies.
- C. Configure a global external Application Load Balancer with weighted request mirroring.
- D. Configure a global external Application Load Balancer with a Service Extension that points to an application running in a VM, which controls which requests go to each application.
Answer: A
Explanation:
Weighted traffic splitting allows you to gradually route a percentage of traffic to the new GKE application while still serving the majority of requests through the Compute Engine instance. This gradual transition minimizes risks and ensures seamless traffic distribution during migration.

NEW QUESTION # 77
Your company's current network architecture has three VPC Service Controls perimeters:
One perimeter (PERIMETER_PROD) to protect production storage buckets
One perimeter (PERIMETER_NONPROD) to protect non-production storage buckets One perimeter (PERIMETER_VPC) that contains a single VPC (VPC_ONE) In this single VPC (VPC_ONE), the IP_RANGE_PROD is dedicated to the subnets of the production workloads, and the IP_RANGE_NONPROD is dedicated to subnets of non-production workloads. Workloads cannot be created outside those two ranges. You need to ensure that production workloads can access only production storage buckets and non-production workloads can access only non-production storage buckets with minimal setup effort. What should you do?
- A. Develop a design that creates a new VPC (VPC_NONPROD) in the same project as VPC_ONE. Migrate all the non-production workloads from VPC_ONE to the PERIMETER_NONPROD perimeter. Remove the PERIMETER_VPC perimeter. Update the PERIMETER_PROD perimeter to include VPC_ONE and the PERIMETER_NONPROD perimeter to include VPC_NONPROD.
- B. Develop a design that removes the PERIMETER_VPC perimeter. Update the PERIMETER_NONPROD perimeter to include the project containing VPC_ONE. Remove the PERIMETER_PROD perimeter.
- C. Develop a design that removes the PERIMETER_VPC perimeter. Update the PERIMETER_PROD perimeter to include the project containing VPC_ONE. Remove the PERIMETER_NONPROD perimeter.
- D. Develop a design that uses the IP_RANGE_PROD and IP_RANGE_NONPROD perimeters to create two access levels, with each access level referencing a single range. Create two ingress access policies with each access policy referencing one of the two access levels. Update the PERIMETER_PROD and PERIMETER_NONPROD perimeters.
Answer: D
Explanation:
Using IP range-based access levels for VPC Service Controls allows segmentation of production and non-production resources within the same VPC. By creating separate access levels and ingress policies for each IP range, you ensure that only production subnets access production buckets and non-production subnets access non-production buckets, providing the required isolation.
