Microsoft Certified: Azure Solutions Architect ExpertDesign infrastructure solutionsMedium
A global enterprise requires a highly available and scalable network solution to connect its numerous branch offices worldwide to Azure and provide inter-branch connectivity. The solution must simplify routing, security, and policy management across the entire global network. Which Azure service is designed for this large-scale, global network connectivity and management?
- AAzure Front Door
- BAzure ExpressRoute
- CAzure VPN Gateway
- DAzure Virtual WAN
Show answer & explanationAnswer & explanation
Correct answer: D. Azure Virtual WAN
Azure Virtual WAN is a networking service that provides optimized and automated branch connectivity to Azure and inter-branch connectivity. It consolidates many networking, security, and routing functionalities into a single operational interface, ideal for large-scale global networks.
Why the other options are wrong
- A. Azure Front Door is a global, scalable entry-point that uses the Microsoft global edge network to create fast, secure, and widely scalable web applications, not a global network connectivity solution for branches.
- B. Azure ExpressRoute provides dedicated private connections from on-premises to Azure, but it's per-connection and does not offer simplified global network management or inter-branch connectivity without additional routing configuration.
- C. Azure VPN Gateway connects individual branches to Azure, but managing many gateways for global scale and inter-branch routing becomes complex.
Azure Virtual WAN
Azure Virtual WAN is a unified networking solution that provides automated and optimized branch-to-Azure connectivity, inter-branch connectivity, and global transit capabilities. It simplifies complex global network architectures.
- Unified global network connectivity
- Automated branch-to-Azure and inter-branch routing
- Integrated security and centralized management
Memory trick: Virtual WAN is the world's biggest virtual highway, connecting all your branches to the cloud and each other, simply.
