You provisioned a Dedicated Interconnect at a colocation nearest us-west2; 75% of workloads are in us-east4 and 25% in us-central1. Minimize data transfer costs when deploying VLAN attachments. What should you do?

The correct option minimizes data transfer costs by placing VLAN attachments closer to the majority of your workloads. Google Cloud charges for egress traffic from a region. By creating VLAN attachments in us-east4 and us-central1, where 75% and 25% of your workloads reside respectively, data travels over Google's private backbone for free from us-west2 to these regions, and then exits locally. The first incorrect option would incur significant cross-region egress charges from us-west2 to us-east4 and us-central1. The other incorrect options involve ordering new Dedicated Interconnects, which is unnecessary and costly, as the existing Interconnect can support multiple VLAN attachments to different regions.
