Question 19

A multinational corporation is undertaking a phased migration of its on-premises network infrastructure to Microsoft Azure. The initial phase involves migrating several critical application workloads residing in distinct on-premises network segments to newly established Azure Virtual Networks (VNets). A fundamental requirement is to maintain continuous, low-latency, and secure bidirectional communication between these newly provisioned VNets and the remaining on-premises resources, as well as between the new VNets themselves. The migration plan necessitates a scalable and manageable network architecture that can accommodate future expansions and prevent IP address exhaustion or conflicts across the interconnected environments. Given the complexity of the existing on-premises network topology and the diverse IP address schemes employed, what is the most effective Azure networking design pattern to achieve these connectivity and management objectives during the migration?

Accepted Answer

Implement a central transit Virtual Network (VNet) that connects to all newly provisioned VNets via VNet peering, and also connects to the on-premises network via Azure VPN Gateway or ExpressRoute, ensuring that "Allow Gateway Transit" is enabled on the transit VNet and "Use Remote Gateways" is enabled on all spoke VNets.

Question 20

A global financial services firm operates a hybrid cloud infrastructure, leveraging Azure for disaster recovery. A key regulatory mandate requires that all sensitive customer transaction data must remain within the continental United States at all times, irrespective of whether the primary or disaster recovery environment is active. The firm utilizes Azure Virtual WAN with multiple regional hubs, including hubs in Europe and Asia, to connect its on-premises data centers and various Azure virtual networks. During a simulated disaster recovery drill, a critical vulnerability was identified where traffic could potentially be misrouted to non-compliant Azure regions, violating data residency laws. Which architectural approach within Azure Virtual WAN and associated security services is most effective in proactively enforcing these strict data residency policies at the network layer, preventing any unauthorized cross-border data flow even during failover events?
