20+ practice questions focused on Implementing a Virtual Private Cloud — one of the most tested topics on the Google Professional Cloud Network Engineer exam. Each question includes a detailed explanation so you learn why the right answer is correct.
Start Implementing a Virtual Private Cloud PracticeA company is deploying a multi-tier web application on Google Cloud. The web tier must be accessible from the internet, while the application tier should only be accessible from the web tier. The database tier must not have any public IP addresses. Which VPC design should be used?
Explanation: Option B is correct because using three separate VPCs with VPC peering enforces strict network segmentation: the web tier VPC has a public subnet with an internet gateway, the application tier VPC is peered only to the web tier VPC (no internet gateway), and the database tier VPC is peered only to the application tier VPC (no public IPs). This design ensures that the database tier has no public IP addresses and is only reachable through the application tier, meeting all security requirements.
An organization has a VPC with custom mode subnets in us-central1 and europe-west1. They create a VM instance in us-central1 with an internal IP 10.0.1.2 and a VM in europe-west1 with internal IP 10.0.2.2. They want to enable communication between these instances using internal IPs. What must be configured?
Explanation: Option A is correct because VPC firewall rules are stateful and must allow ingress traffic from the source subnet (10.0.1.0/24) or the specific source instance (10.0.1.2) to the destination VM in europe-west1. By default, VPCs have an implied deny-all ingress rule, so explicit firewall rules are required to permit traffic between subnets in different regions within the same VPC. The rule should specify the source IP range or tag and the destination protocol/port (e.g., ICMP, TCP/22) to enable communication.
A startup wants to create a VPC with a subnet that can grow automatically as they add more VM instances. Which subnet type should they use?
Explanation: An auto mode subnet automatically creates subnets in each region and assigns IP address ranges from a predefined pool that can expand as you add more VM instances. This allows the subnet to grow without manual intervention, making it ideal for startups that need dynamic scaling.
A company has a VPC with a subnet 10.0.1.0/24 in us-central1. They need to add a new subnet for a Kubernetes cluster that requires a secondary IP range for pods. The primary IP range of the new subnet must be 10.0.2.0/24. What is the correct way to create this subnet?
Explanation: Option A is correct because in Google Cloud VPC, a subnet can have both a primary IP range and one or more secondary IP ranges, and these secondary ranges must be specified at subnet creation time. For a Kubernetes cluster, the secondary range for pods is required, and it cannot be added after the subnet is created; it must be defined during the initial subnet creation.
An organization is migrating to Google Cloud and requires connectivity between their on-premises network and VPC. They plan to use Cloud VPN with dynamic routing (BGP). Which VPC feature is required for this setup?
Explanation: Cloud Router is required when using Cloud VPN with dynamic routing (BGP) because it manages the BGP sessions between the on-premises router and the Google Cloud VPN gateway. It exchanges routes dynamically, enabling automatic route propagation and failover without manual static route configuration.
