• Chose A1

  The correct answer is A because it ensures centralized networking administration by deploying VLAN attachments and the Dedicated Interconnect in the host project of a Shared VPC. This allows the networking team to manage connectivity while giving departments the flexibility to use subnets from the Shared VPC in their service projects. This setup provides cost-effective, low-latency access to Google Cloud with 10 Gbps connectivity.

  I think A is the right answer. When using a Shared VPC Network with Dedicated Interconnect, consider the following: VLAN attachments and Cloud Routers for Dedicated Interconnect must exist in the Shared VPC host project, not in any service projects attached to the host project. When you create the Cloud Router to manage a VLAN attachment, you specify a particular VPC network. Effectively, the combination of a VLAN attachment and its associated Cloud Router are unique to a given Shared VPC network. Service Project Admins can create VMs that use subnets in a Shared VPC network of a host project based on the permissions they have to the host project. VMs that use the Shared VPC network can use the custom dynamic routes for VLAN attachments available to that network.

  Answer is A: https://cloud.google.com/network-connectivity/docs/interconnect/concepts/best-practices Configure VLAN attachments in the Shared VPC host project 'In a Shared VPC network, configure all VLAN attachments, not physical Interconnect connections (ports), in the host project. For more information about connecting attachments to Shared VPC networks'... https://cloud.google.com/network-connectivity/docs/interconnect/how-to/enabling-multiple-networks-access-same-attachment 'You must create VLAN attachments and Cloud Routers for an Interconnect connection only in the Shared VPC host project'
