Question 1

Your company's current network architecture has two VPCs that are connected by a dual-NIC instance that acts as a bump-in-the-wire firewall between the two VPCs. Flows between pairs of subnets across the two VPCs are working correctly. Suddenly, you receive an alert that none of the flows between the two VPCs are working anymore. You need to troubleshoot the problem. What should you do? (Choose 2 answers)

Options :

A : Verify that the dual-NIC instance has not been added to a backend service.

B : Verify that a public IP address has not been assigned to any network interface of the dual-NIC instance.

C : Use Cloud Logging to verify that there were no modifications to the VPC firewall rules or policies that were applied to the two network interfaces of the dual-NIC instance.

D : Verify that a VPC Service Controls perimeter has not been enabled for the project that contains the two VPCs and the dual-NIC instance.

E : Verify that the dual-NIC instance has the --can-ip-forward attribute enabled.

Answer: C,E

Question 2

You are designing the network architecture for your organization. Your organization has three developer teams: Web, App, and Database. All of the developer teams require access to Compute Engine instances to perform their critical tasks. You are part of a small network and security team that needs to provide network access to the developers. You need to maintain centralized control over network resources, including subnets, routes, and firewalls. You want to minimize operational overhead. How should you design this topology?

Options :

A : Configure a host project with a Shared VPC. Create service projects for Web, App, and Database.

B : Configure one VPC for Web, one VPC for App, and one VPC for Database. Configure HA VPN between each VPC.

C : Configure three Shared VPC host projects, each with a service project: one for Web, one for App, and one for Database.

D : Configure one VPC for Web, one VPC for App, and one VPC for Database. Use VPC Network Peering to connect all VPCs in a full mesh.

Answer: C

Question 3

Your organization recently exposed a set of services through a global external Application Load Balancer. After conducting some testing, you observed that responses would intermittently yield a non-HTTP 200 response. You need to identify the error. What should you do? (Choose 2 answers)

Options :

A : Access a VM in the VPC through SSH, and try to access a backend VM directly. If the request is successful from the VM, increase the quantity of backends.

B : Enable and review the health check logs. Review the error responses in Cloud Logging.

C : Validate the health of the backend service. Enable logging on the load balancer, and identify the error response in Cloud Logging. Determine the cause of the error by reviewing the statusDetails log field.

D : Delete the load balancer and backend services. Create a new passthrough Network Load Balancer. Configure a failover group of VMs for the backend.

E : Validate the health of the backend service. Enable logging for the backend service, and identify the error response in Cloud Logging. Determine the cause of the error by reviewing the statusDetails log field.

Answer: B,C

Question 4

You work for a university that is migrating to GCP. These are the cloud requirements: • On-premises connectivity with 10 Gbps • Lowest latency access to the cloud • Centralized Networking Administration Team New departments are asking for on-premises connectivity to their projects. You want to deploy the most costefficient interconnect solution for connecting the campus to Google Cloud. What should you do?

Options :

A : Use Shared VPC, and deploy the VLAN attachments and Interconnect in the host project.

B : Use Shared VPC, and deploy the VLAN attachments in the service projects. Connect the VLAN attachment to the Shared VPC's host project.

C : Use standalone projects, and deploy the VLAN attachments in the individual projects. Connect the VLAN attachment to the standalone projects' Interconnects.

D : Use standalone projects and deploy the VLAN attachments and Interconnects in each of the individual projects.

Answer: A

Question 5

You need to configure a Google Kubernetes Engine (GKE) cluster. The initial deployment should have 5 nodes with the potential to scale to 10 nodes. The maximum number of Pods per node is 8. The number of services could grow from 100 to up to 1024. How should you design the IP schema to optimally meet this requirement?

Options :

A : Configure a /28 primary IP address range for the node IP addresses. Configure a (25 secondary IP range for the Pods. Configure a /22 secondary IP range for the Services.

B : Configure a /28 primary IP address range for the node IP addresses. Configure a /25 secondary IP range for the Pods. Configure a /21 secondary IP range for the Services.

C : Configure a /28 primary IP address range for the node IP addresses. Configure a /28 secondary IP range for the Pods. Configure a /21 secondary IP range for the Services.

D : Configure a /28 primary IP address range for the node IP addresses. Configure a /24 secondary IP range for the Pads. Configure a /22 secondary IP range for the Services.
