You need to enable network traffic between Compute Engine instance groups in two different projects, each with its own VPC. What should you do?

Correct answer: Verify that both projects are in a GCP Organization. Share the VPC from one project and request that the Compute Engine instances in the other project use this shared VPC..
Why this is the answer
The correct solution involves using Shared VPC. Shared VPC allows instances from multiple service projects to connect to a common host project's VPC network, enabling secure and efficient communication between resources in different projects while maintaining centralized network control. For Shared VPC to work, both projects must belong to the same Google Cloud organization. Creating new VPCs and moving instances is inefficient and doesn't leverage Google Cloud's networking features for inter-project communication. Simply being a Project Administrator doesn't inherently solve the networking challenge; Shared VPC is the specific Google Cloud feature designed for this scenario.
