Google Professional Cloud Network Engineer Exam Questions
- Topic 1: Designing and planning a Google Cloud network: This section of the exam measures the skills of Cloud Architects and covers the high-level planning of network infrastructure on Google Cloud. It involves designing overall network architecture with considerations for high availability, security, and hybrid connectivity. The domain includes planning DNS topology, selecting appropriate load balancers, designing VPC networks, and creating resilient multi-cloud architectures. It also encompasses planning for GKE networking, IAM roles in Shared VPC environments, microsegmentation strategies, and connectivity to managed services while differentiating between network tiers and implementing VPC Service Controls.
- Topic 2: Implementing Virtual Private Cloud (VPC) networks: This section of the exam measures the skills of Network Engineers and focuses on the practical implementation of VPC networks. It includes configuring VPCs, VPC Network Peering, and Shared VPC environments. The domain covers setting up routing configurations, including static and dynamic routing, implementing the Network Connectivity Center, and configuring Google Kubernetes Engine clusters with proper networking setups. It also involves configuring and managing Cloud Next Generation Firewall rules, including creating firewall policies, configuring intrusion prevention services, and implementing fully qualified domain name firewall objects.
- Topic 3: Configuring managed network services: This section of the exam measures the skills of Cloud Operations Engineers and encompasses the configuration of various Google Cloud networking services. It includes setting up load balancing with proper backend services and health checks, configuring Google Cloud Armor security policies with WAF rules and DDoS protection, and implementing Cloud CDN for content delivery. The domain also covers managing Cloud DNS zones and records, securing internet egress traffic through NAT configurations, and implementing network packet inspection solutions using multi-NIC VMs and internal load balancers.
- Topic 4: Implementing hybrid network interconnectivity: This section of the exam measures the skills of Connectivity Specialists and focuses on establishing connections between Google Cloud and other environments. It involves configuring Cloud Interconnect solutions, including Dedicated Interconnect, Partner Interconnect, and Cross-Cloud Interconnect, with proper VLAN attachments. The domain covers setting up site-to-site IPSec VPNs, including HA VPN configurations, implementing Cloud Router with BGP attributes and BFD, and configuring Network Connectivity Center for hybrid connectivity, including creating hybrid spokes and establishing site-to-site data transfer.
- Topic 5: Managing, monitoring, and troubleshooting network operations: This section of the exam measures the skills of Network Administrators and covers the ongoing management of Google Cloud network environments. It includes implementing logging and monitoring using Google Cloud Observability for various networking components. The domain encompasses maintaining and troubleshooting connectivity issues, including traffic management with load balancers, firewall rule tuning, and VPN troubleshooting. It also involves using Network Intelligence Center tools for monitoring and diagnostics, including Network Topology visualization, Connectivity Tests, Performance Dashboard analysis, Firewall Insights, and Network Analyzer for identifying and resolving network issues.

Your company offers a popular gaming service. Your instances are deployed with private IP addresses, and external access is granted through a global load balancer. You believe you have identified a potential malicious actor, but aren't certain you have the correct client IP address. You want to identify this actor while minimizing disruption to your legitimate users.
What should you do?
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?
You are 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 doo
The correct answer is C. Create a single Shared VPC and attach each Google Cloud project as a service project.
This answer is based on the following facts:
The other options are not correct because:
Option B is not feasible. Creating a single project and single VPC for each internal project will not meet the requirement of having separate project owners for each internal project. You will have only one project owner who can manage all the Google Cloud resources in the same project.
Option D is not optimal. Creating a Shared VPC and service project for each internal project will not meet the requirement of having a simple and reusable code with centralized management. You will need to create and maintain multiple Shared VPCs, which will increase the complexity and cost of the network infrastructure. You will also have more Terraform code to write and manage for each Shared VPC.
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?
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.
Your organization has a Google Cloud Virtual Private Cloud (VPC) with subnets in us-east1, us-west4, and europe-west4 that use the default VPC configuration. Employees in a branch office in Europe need to access the resources in the VPC using HA VPN. You configured the HA VPN associated with the Google Cloud VPC for your organization with a Cloud Router deployed in europe-west4. You need to ensure that the users in the branch office can quickly and easily access all resources in the VPC. What should you do?
