Google Cloud Certified - Professional Cloud Network Engineer Questions and Answers

Question 1

You are designing a new global application using Compute Engine instances that will be exposed by a global HTTP(S) load balancer. You need to secure your application from distributed denial-of-service and application layer (layer 7) attacks. What should you do?

Options:

A.

Configure VPC Service Controls and create a secure perimeter. Define fine-grained perimeter controls and enforce that security posture across your Google Cloud services and projects.

B.

Configure a Google Cloud Armor security policy in your project, and attach it to the backend service to secure the application.

C.

Configure VPC firewall rules to protect the Compute Engine instances against distributed denial-of-service attacks.

D.

Configure hierarchical firewall rules for the global HTTP(S) load balancer public IP address at the organization level.

Question 2

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?

Options:

A.

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.

B.

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.

C.

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.

D.

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.

Question 3

Your company's web server administrator is migrating on-premises backend servers for an application to GCP. Libraries and configurations differ significantly across these backend servers. The migration to GCP will be lift-and-shift, and all requests to the servers will be served by a single network load balancer frontend. You want to use a GCP-native solution when possible.

How should you deploy this service in GCP?

Options:

A.

Create a managed instance group from one of the images of the on-premises servers, and link this instance group to a target pool behind your load balancer.

B.

Create a target pool, add all backend instances to this target pool, and deploy the target pool behind your load balancer.

C.

Deploy a third-party virtual appliance as frontend to these servers that will accommodate the significant differences between these backend servers.

D.

Use GCP's ECMP capability to load-balance traffic to the backend servers by installing multiple equal-priority static routes to the backend servers.
