To allow connection across a new Dedicated Interconnect to your data center, you need to create a Cloud Router instance in your organization's Google Cloud environment. Cloud Router is a Google Cloud networking service that enables dynamic routing of traffic within and between Virtual Private Cloud (VPC) networks.

In this scenario, the organization's host project has three service projects attached to it, which are Sales, Marketing, and IT projects. Each project has its own VPC network. To determine where to create the Cloud Router instance, we need to consider the following:

  • A Cloud Router instance can only be associated with one VPC network.
  • The Dedicated Interconnect is connected to the host project's VPC network.
  • The goal is to allow connection across the Dedicated Interconnect to the data center.

Based on the above considerations, the recommended approach is to create the Cloud Router instance in the host project's VPC network. This way, the Cloud Router instance can connect to all the VPC networks within the host project and route traffic across the Dedicated Interconnect to the data center.

Therefore, the correct answer is option C: VPC network in the Host Project. Option A, which suggests creating a Cloud Router instance in all projects, is not recommended because it would result in multiple Cloud Router instances, which can lead to unnecessary complexity and management overhead. Option B suggests creating a Cloud Router instance in the IT project's VPC network, which is not ideal because it would only allow IT project traffic to flow through the Dedicated Interconnect. Option D suggests creating a Cloud Router instance in all three projects, which is not necessary and can lead to unnecessary management overhead.
