An organization is planning to connect its existing on-premises network, which uses the IP range , to Google Cloud using Cloud VPN. The cloud engineer must design a Virtual Private Cloud (VPC) network that prevents IP address collisions with the on-premises environment and allows precise control over subnet IP address allocations in specific regions. Which VPC network creation mode should the cloud engineer select?
- Create a custom-mode VPC network and manually define subnets with non-overlapping CIDR blocks.Answer
- BCreate an auto-mode VPC network so GCP automatically assigns non-overlapping subnets in all regions.
- CCreate a legacy-mode VPC network to allocate a single global IP range for all resources.
- DCreate an auto-mode VPC network and edit the default subnet CIDR ranges after network creation.
Answer
Create a custom-mode VPC network and manually define subnets with non-overlapping CIDR blocks.
Custom-mode VPC networks start with zero automatically created subnets. This grants administrators full control to define custom subnet names, regions, and explicit CIDR ranges that do not collide with on-premises networks or other cloud environments.
Step-by-Step Solution
Key Concept
Custom-mode VPC networks allow complete control over subnet creation and IP address range allocation, which is necessary for hybrid cloud integrations.
