Question

Your organization is connecting their Shared VPC network to their on-premises data center by using Dedicated Interconnect to provide connectivity to all of its service projects. You need to create a design to configure your VLAN attachments and Cloud Routers. You also want to achieve a 99.9% Cloud Interconnect SLA based on Google Cloud s reference design. What should you do?

Explanation

To achieve a 99.9% SLA for Cloud Interconnect, you must deploy two connections in separate edge availability domains in different co-location facilities. This design ensures redundancy and eliminates single points of failure. By creating separate VLAN attachments and Cloud Routers in the Shared VPC host project, the centralized network can manage routing and connectivity effectively, while providing high availability and seamless failover for all service projects. This approach aligns with Google's recommended practices for achieving the required SLA.
