Microsoft Certified: Azure Solutions Architect ExpertDesign infrastructure solutionsHard
A global enterprise requires a highly available and scalable network solution to connect its numerous branch offices worldwide to its Azure-hosted applications and services. The solution must provide centralized network management, optimized routing, and secure connectivity over a global backbone, replacing complex VPN setups at each branch. Which Azure networking service should be recommended?
- AAzure VPN Gateway (Site-to-Site VPN)
- BAzure Front Door
- CAzure ExpressRoute
- DAzure Virtual WAN
Show answer & explanationAnswer & explanation
Correct answer: D. Azure Virtual WAN
Azure Virtual WAN (VWan) is a unified networking solution that provides optimized, automated, and global connectivity for branch offices to Azure and on-premises environments. It offers centralized management, secure connectivity (VPN, ExpressRoute), and optimized routing over Microsoft's global network backbone, specifically designed to simplify large-scale branch connectivity and address the complexity of managing many VPNs.
Why the other options are wrong
- A. Azure VPN Gateway with Site-to-Site VPNs can connect branches, but managing 'numerous' VPNs globally becomes complex and lacks centralized management and optimized global routing of Virtual WAN.
- B. 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, but it is not a solution for general branch office network connectivity to Azure services.
- C. Azure ExpressRoute provides dedicated private connections, offering high bandwidth and low latency, but it's primarily for connecting a few key corporate sites, not designed for the global branch office connectivity and centralized management of a large enterprise.
Azure Virtual WAN
A unified networking solution that provides optimized, automated, and global connectivity for branch offices, users, and Azure-hosted workloads.
- Centralizes network management, security, and routing.
- Supports various connectivity types: VPN, ExpressRoute, Point-to-Site.
- Optimized global backbone for branch-to-cloud and branch-to-branch connectivity.
Memory trick: Virtual WAN: 'Virtual'ly 'Wan't for nothing in global networking.
