You are the architect of the ACME shipping group. You are responsible for designing the integration between two internal applications that are running on 2 different virtual networks. The two applications require to send data back and forth regularly. Which connectivity solution should be used?
VNet peering is correct, as this is the solution required to connect resources on the VNets to each other as several VNets can be linked to each other. User Defined Routing (UDR) will not work without VNet peering as this is used as a routing table between resources. Network Security Groups will not accomplish this task as NSG’s allow/block traffic and does not establish a connection between VNets, However NSG rules should be viewed to ensure that traffic between the VNets is not blocked if you have a long list of deny rules.
