Question

A financial services company has AWS VPCs deployed in us-east-1 and eu-west-1. They already have a single AWS Direct Connect connection terminating at a colocation facility in Virginia. The network team wants both regions' VPCs to be reachable over this existing physical Direct Connect connection without deploying additional cross-connects or public internet transit. Which AWS construct enables this multi-region private reachability over the single Direct Connect connection?

Accepted Answer

Associate a Direct Connect gateway with a private virtual interface (VIF) and attach the VPCs from both regions

Answer

Create a separate public virtual interface (VIF) for each region and route traffic through S3 endpoints

Answer

Deploy a VPC peering connection between us-east-1 and eu-west-1 and advertise it over a hosted VIF

Answer

Provision a second Direct Connect connection in the eu-west-1 region and use inter-region VPN as a backup
