Where should you deploy the Cloud Router instance when configuring a new Dedicated Interconnect connection between your on-premises data center and your Google Cloud environment, given that Sales, Marketing, and IT each have service projects attached to the organization's host project?
Explanation:
In a Shared VPC setup, the host project owns the VPC network and shares it with service projects (Sales, Marketing, IT). Dedicated Interconnect resources, including VLAN attachments and Cloud Routers, must reside in the host project's VPC network. This is because the host project centralizes network management, and service projects cannot directly manage interconnect configurations. Creating the Cloud Router in the host project ensures it can handle BGP routing for the Dedicated Interconnect connection shared across all service projects.
