Answer: Create two Cloud Interconnect connections in different edge availability domains of two different co-location facilities in a project that will contain your connections. Create one VLAN attachment and Cloud Router for each physical interconnect in the Shared VPC host project.
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.

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?
A
Create two Cloud Interconnect connections in different edge availability domains of two different co-location facilities in a project that will contain your connections. Create one VLAN attachment and Cloud Router for each physical interconnect in the Shared VPC host project.
B
Create two Interconnect connections in different edge availability domains of the co-location facility in a project that will contain your connections. Create one VLAN attachment for each physical Cloud Interconnect connection and a single Cloud Router in the Shared VPC host project.
C
Create two Cloud Interconnect connections in different edge availability domains of the co-location facility in a project that will contain your connections. Create one VLAN attachment for each physical interconnect and a single Cloud Router in the service projects.
D
Create two Cloud Interconnect connections in different edge availability domains of the co-location facility in a project that will contain your connections. Create a Cloud Router in the Shared VPC host project and the VLAN attachments in the Shared VPC service projects.
