Question 1

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.

Answer: A

Question 2

You configured Cloud VPN with dynamic routing via Border Gateway Protocol (BGP). You added a custom route to advertise a network that is reachable over the VPN tunnel. However, the on-premises clients still cannot reach the network over the VPN tunnel. You need to examine the logs in Cloud Logging to confirm that the appropriate routers are being advertised over the VPN tunnel. Which filter should you use in Cloud Logging to examine the logs?

Options :

A : resource.type= “gce_router”

B : resource.type= “gce_network_region”

C : resource.type= “vpn_tunnel”

D : resource.type= “vpn_gateway”

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 want to apply a new Cloud Armor policy to an application that is deployed in Google Kubernetes Engine (GKE). You want to find out which target to use for your Cloud Armor policy. Which GKE resource should you use?

Options :

A : GKE Node

B : GKE Pod

C : GKE Cluster

D : GKE Ingress

Answer: D

Question 5

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.
