Your company has two on-premises sites in New York and Los Angeles and Azure virtual networks in the East US Azure region and the West US Azure region.
Each on-premises site has Azure ExpressRoute circuits to both regions.
You need to recommend a solution that meets the following requirements:
Outbound traffic to the Internet from workloads hosted on the virtual networks must be routed through the closest available on-premises site.
If an on-premises site fails, traffic from the workloads on the virtual networks to the Internet must reroute automatically to the other site.
What should you include in the recommendation?
