Difficulty: EasyPlanning Virtual Private Cloud (VPC) Networks and Subnets

An engineer is planning the initial virtual private cloud (VPC) topology for an enterprise workload in Google Cloud. Which two statements accurately describe Google Cloud VPC networks and subnets? (Select TWO answers.)

  1. VPC networks are global resources, whereas subnets are regional resources.Answer
  2. Custom mode VPC networks allow administrators to manually define IP address ranges for subnets in chosen regions.Answer
  3. C
    Auto mode VPC networks create subnets for each availability zone using randomized IP ranges.
  4. D
    An existing subnet primary IP range can be expanded even if the new range overlaps with a peered VPC network range.

Answer

Google Cloud VPC networks are global resources containing regional subnets, and custom mode VPC networks allow administrators to explicitly define IP address ranges for subnets in selected regions.
Google Cloud VPC networks are global resources capable of hosting resources across multiple regions, whereas subnets belong to specific regions. Furthermore, custom mode VPC networks give cloud engineers explicit administrative control to create subnets with specific IP address ranges only in required regions.

Step-by-Step Solution

1
Evaluate the architectural scope of VPC networks and subnets in Google Cloud.
Recognize that VPC networks are global entities that span across regions, while subnets are regional objects bound to a specific GCP region.
Understanding resource scope is fundamental when planning network topology and regional resource placement.
2
Analyze the operational differences between custom mode and auto mode VPC networks.
Determine that custom mode VPCs provide complete control over subnet creation, IP CIDR allocation, and regional placement.
Enterprise networks generally utilize custom mode VPCs to prevent IP space overlap with existing on-premises or peered networks.
