Microsoft Certified: Azure Solutions Architect ExpertDesign infrastructure solutionsEasy
A company requires a network solution to securely connect its on-premises data center to Azure virtual networks. The connection needs to provide high bandwidth, low latency, and guaranteed uptime, bypassing the public internet. Which Azure networking service should be recommended?
- AAzure ExpressRoute
- BAzure Virtual WAN
- CAzure VPN Gateway
- DAzure Private Link
Show answer & explanationAnswer & explanation
Correct answer: A. Azure ExpressRoute
Azure ExpressRoute creates a private, dedicated connection between an on-premises network and Azure, bypassing the public internet. This provides higher bandwidth, lower latency, and guaranteed uptime, meeting all the specified requirements.
Why the other options are wrong
- B. Azure Virtual WAN is a networking service that simplifies complex network deployments, but ExpressRoute is the underlying technology for dedicated private connectivity.
- C. Azure VPN Gateway uses encrypted tunnels over the public internet, which does not guarantee bandwidth or bypass the public internet.
- D. Azure Private Link provides private connectivity to Azure PaaS services, not site-to-site connectivity for an on-premises data center.
Azure ExpressRoute
A service that creates a private, dedicated connection between an on-premises network and Microsoft Azure, bypassing the public internet.
- Private connection, not over public internet.
- High bandwidth, low latency.
- Guaranteed uptime (SLA).
- Ideal for hybrid cloud scenarios with strict performance/security needs.
Memory trick: ExpressRoute is the 'express lane' to Azure.
