Google Cloud Certified - Professional Cloud Network Engineer Questions and Answers

Question 1

Your end users are located in close proximity to us-east1 and europe-west1. Their workloads need to communicate with each other. You want to minimize cost and increase network efficiency.

How should you design this topology?

Options:

A.

Create 2 VPCs, each with their own regions and individual subnets. Create 2 VPN gateways to establish connectivity between these regions.

B.

Create 2 VPCs, each with their own region and individual subnets. Use external IP addresses on the instances to establish connectivity between these regions.

C.

Create 1 VPC with 2 regional subnets. Create a global load balancer to establish connectivity between the regions.

D.

Create 1 VPC with 2 regional subnets. Deploy workloads in these subnets and have them communicate using private RFC1918 IP addresses.

Question 2

You need to create a GKE cluster in an existing VPC that is accessible from on-premises. You must meet the following requirements:

    IP ranges for pods and services must be as small as possible.

    The nodes and the master must not be reachable from the internet.

    You must be able to use kubectl commands from on-premises subnets to manage the cluster.

How should you create the GKE cluster?

Options:

A.

• Create a private cluster that uses VPC advanced routes.

•Set the pod and service ranges as /24.

•Set up a network proxy to access the master.

B.

• Create a VPC-native GKE cluster using GKE-managed IP ranges.

•Set the pod IP range as /21 and service IP range as /24.

•Set up a network proxy to access the master.

C.

• Create a VPC-native GKE cluster using user-managed IP ranges.

•Enable a GKE cluster network policy, set the pod and service ranges as /24.

•Set up a network proxy to access the master.

•Enable master authorized networks.

D.

• Create a VPC-native GKE cluster using user-managed IP ranges.

•Enable privateEndpoint on the cluster master.

•Set the pod and service ranges as /24.

•Set up a network proxy to access the master.

•Enable master authorized networks.

Question 3

Your company’s on-premises network is connected to a VPC using a Cloud VPN tunnel. You have a static route of 0.0.0.0/0 with the VPN tunnel as its next hop defined in the VPC. All internet bound traffic currently passes through the on-premises network. You configured Cloud NAT to translate the primary IP addresses of Compute Engine instances in one region. Traffic from those instances will now reach the internet directly from their VPC and not from the on-premises network. Traffic from the virtual machines (VMs) is not translating addresses as expected. What should you do?

Options:

A.

Lower the TCP Established Connection Idle Timeout for the NAT gateway.

B.

Add firewall rules that allow ingress and egress of the external NAT IP address, have a target tag that is on the Compute Engine instances, and have a priority value higher than the priority value of the default route to the VPN gateway.

C.

Add a default static route to the VPC with the default internet gateway as the next hop, the network tag associated with the Compute Engine instances, and a higher priority than the priority of the default route to the VPN tunnel.

D.

Increase the default min-ports-per-vm setting for the Cloud NAT gateway.
