An organization is preparing to deploy a multi-region workload across `us-central1` and `europe-west1` in Google Cloud. The infrastructure must connect via Cloud VPN to an existing on-premises data center using the IPv4 CIDR block . The cloud networking team needs to plan the Virtual Private Cloud (VPC) network and subnets to prevent IP routing conflicts and accommodate future capacity growth. Which TWO design practices should the team follow? (Select TWO.)
- Create the Virtual Private Cloud (VPC) network in Custom mode rather than Auto mode.Cevap
- Allocate unique, non-overlapping internal IP ranges (such as for `us-central1` and for `europe-west1`) for each regional subnet.Cevap
- CDeploy an Auto mode VPC network so Google Cloud automatically manages and expands subnet CIDRs dynamically across regions when IP addresses run low.
- DAssign the CIDR range to the `us-central1` subnet to simplify subnet routing tables shared with the on-premises data center.
Cevap
The team should create the VPC network in Custom mode rather than Auto mode and allocate unique, non-overlapping internal IP ranges (such as 10.10.0.0/24 for us-central1 and 10.20.0.0/24 for europe-west1) for each regional subnet.
Selecting Custom mode gives network administrators full control over subnet creation and IP address assignment. Defining distinct, non-overlapping IP address ranges for each region ensures seamless hybrid connectivity over Cloud VPN without packet drops or routing conflicts.
