Answer: Order a new Dedicated Interconnect for a colocation facility closest to us-east4, and use VPC global routing to access workloads in us-central1.
To minimize data transfer costs, it's crucial to place VLAN attachments in regions where the majority of workloads are located to avoid cross-region egress fees. Given that 75% of the workloads are in us-east4, the most cost-effective solution is to order a new Dedicated Interconnect for a colocation facility closest to us-east4. This allows for VLAN attachments to be deployed in us-east4, where the majority of the workloads are, thus minimizing data transfer costs. The remaining 25% of workloads in us-central1 can be accessed using VPC global routing, which, while it may incur some costs, is more economical than the alternatives given the distribution of workloads. This approach is more cost-effective than keeping the existing Dedicated Interconnect in us-west2 or ordering a new one for us-central1, as it directly addresses the region with the highest workload concentration.

You have successfully provisioned a single Dedicated Interconnect with the physical connection located at a colocation facility nearest to us-west2. Seventy-five percent of your workloads are in us-east4, and the remaining twenty-five percent are in us-central1. All workloads share the same network traffic profile. How should you configure VLAN attachments to minimize data transfer costs?
A
Keep the existing Dedicated interconnect. Deploy a VLAN attachment to a Cloud Router in us-west2, and use VPC global routing to access workloads in us-east4 and us-central1.
B
Keep the existing Dedicated Interconnect. Deploy a VLAN attachment to a Cloud Router in us-east4, and deploy another VLAN attachment to a Cloud Router in us-central1.
C
Order a new Dedicated Interconnect for a colocation facility closest to us-east4, and use VPC global routing to access workloads in us-central1.
D
Order a new Dedicated Interconnect for a colocation facility closest to us-central1, and use VPC global routing to access workloads in us-east4.
