What does Auto Mode in GCP imply?

Auto Mode in Google Cloud Platform (GCP) implies that VPC networks are pre-configured with subnets. When a VPC network is created in Auto Mode, it automatically creates a subnet in each region that Google Cloud services are available in. Each of these subnets is assigned a predefined IP range that corresponds with the region.

Choosing to create a VPC in Auto Mode means you do not need to manually define each subnet, which eases the process of VPC setup and facilitates quick deployment of resources in multiple regions. This automatic setup is particularly useful for users who want a simpler and faster way to get started with GCP, as it minimizes the initial configuration complexity.

In contrast, the other options describe scenarios or requirements that are not accurate within the context of Auto Mode, where the automatic subnet creation is a significant feature.
