Question

You manage networking for Contoso. Two teams have independently deployed VNets: VNet-A uses 10.10.0.0/16 in East US, and VNet-B uses 10.10.0.0/16 in West US. Management now requires that resources in both VNets communicate directly over the Azure backbone with the lowest ongoing cost and management overhead. What must you do before this connectivity can be established?

Accepted Answer

Re-address one of the VNets to a non-overlapping range, then create a VNet peering between them

Answer

Deploy VPN gateways in each VNet and configure a VNet-to-VNet connection to translate the overlapping addresses

Answer

Create the VNet peering as-is; Azure automatically performs NAT on overlapping address spaces during peering

Answer

Add a second, non-overlapping address space to VNet-B and enable peering while keeping the original range
