Your organization is using Dedicated Interconnect to connect its Shared VPC network to an on-premises data center, enabling connectivity for all service projects. You must design the VLAN attachments and Cloud Routers configuration while ensuring a 99.9% Cloud Interconnect SLA based on Google Cloud's reference architecture. What steps should you take?
Explanation:
To achieve a 99.9% SLA with Dedicated Interconnect, it's essential to follow Google's reference design which mandates two connections in different edge availability domains (EADs) within the same metro but in separate colocation facilities for redundancy. Each connection should have its own VLAN attachment and Cloud Router in the Shared VPC host project to ensure there's no single point of failure. Option A adheres to these requirements by creating two connections in different EADs and provisioning a VLAN attachment and Cloud Router for each in the host project. Options B, C, and D fail to meet these criteria either by using a single Cloud Router or incorrectly placing resources in service projects.
