Correct answer: A subnet is regional and cannot span multiple regions; you must create separate subnets with distinct non-overlapping ranges in each region..
Why this is the answer
GCP subnets are regional resources, meaning they are confined to a single region. You cannot create a single subnet that spans multiple regions. Therefore, to have network resources in both us-central1 and europe-west1, you must create separate subnets in each region. These subnets must have distinct, non-overlapping IP address ranges to avoid routing conflicts. While VPC networks are global, subnets within them are regional. Global subnets are not a feature in GCP, and VPC Peering connects separate VPC networks, it does not make a single subnet span regions.
