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 on-premises data center has 2 routers connected to your Google Cloud environment through a VPN on each router. All applications are working correctly; however, all of the traffic is passing across a single VPN instead of being load-balanced across the 2 connections as desired.
During troubleshooting you find:
* Each on-premises router is configured with a unique ASN.
* Each on-premises router is configured with the same routes and priorities.
* Both on-premises routers are configured with a VPN connected to a single Cloud Router.
* BGP sessions are established between both on-premises routers and the Cloud Router.
* Only 1 of the on-premises router's routes are being added to the routing table.
What is the most likely cause of this problem?
You need to create the technical architecture for hybrid connectivity from your data center to Google Cloud This will be managed by a partner. You want to follow Google-recommended practices for production-level applications. What should you do?
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?
VPC Network Peering is the most cost-effective and high-performance method for connecting two VPCs. Since one VPC uses privately used public IP (PUPI) ranges, you need to configure peering to allow the export and import of subnet routes with public IP addresses. Firewall rules can be used to control traffic between the resources.
Your company's security team wants to limit the type of inbound traffic that can reach your web servers to protect against security threats. You need to configure the firewall rules on the web servers within your Virtual Private Cloud (VPC) to handle HTTP and HTTPS web traffic for TCP only. What should you do?
Your team deployed two applications in GKE that are exposed through an external Application Load Balancer. When queries are sent to www.mountkirkgames.com/sales and www.mountkirkgames.com/get-an-analysis, the correct pages are displayed. However, you have received complaints that www.mountkirkgames.com yields a 404 error. You need to resolve this error. What should you do?
The 404 error is occurring because there is no default backend defined for requests to the root URL. Defining the default backend in the Ingress YAML file ensures that requests to www.mountkirkgames.com are routed to the correct service.
