Answer: VPC peering
The question requires connecting two different GCP Organizations (customer and partner company) with the strict requirement that communication must not traverse the public internet. VPC peering (Option A) is the correct solution because it establishes private connectivity between VPC networks across different GCP Organizations using Google's private network backbone, ensuring no internet exposure. Cloud VPN (Option B) is incorrect as it encrypts traffic but still traverses the public internet. Cloud Interconnect (Option C) is designed for connecting on-premises networks to GCP, not for inter-GCP connectivity. Shared VPC (Option D) is for sharing resources within a single GCP Organization, not across different organizations. The community discussion strongly supports Option A with 89% consensus and high upvotes, emphasizing that VPC peering is the only option that meets the 'no public internet' requirement for cross-organization GCP connectivity.
