Microsoft Certified: Azure Solutions Architect ExpertDesign infrastructure solutionsMedium
A global enterprise requires a highly available and scalable network solution to connect its on-premises data centers, branch offices, and Azure Virtual Networks (VNets) across multiple regions. The solution must provide centralized network management, optimized routing, and support for hybrid connectivity. Which Azure service is BEST suited for this scenario?
- AAzure Virtual WAN
- BAzure VPN Gateway
- CAzure ExpressRoute
- DAzure Load Balancer
Show answer & explanationAnswer & explanation
Correct answer: A. Azure Virtual WAN
Azure Virtual WAN is a networking service that provides optimized, automated, and global connectivity for branches, data centers, and Azure VNets. It offers centralized network management, integrated security, and supports both VPN and ExpressRoute connections, making it ideal for large-scale, globally distributed hybrid networks.
Why the other options are wrong
- B. Azure VPN Gateway provides site-to-site VPN connectivity but lacks the centralized management, global scale, and optimized routing capabilities of Virtual WAN for a large enterprise.
- C. Azure ExpressRoute provides dedicated private connectivity but needs to be combined with other services for centralized management and global hub-and-spoke architecture across many sites and Azure regions.
- D. Azure Load Balancer distributes traffic to backend resources and is not a solution for wide-area network connectivity or centralized network management across hybrid environments.
