Difficulty: MediumAzure Virtual Networks, ExpressRoute, and VPN Gateway

A retail corporation wants to link its centralized inventory management system at a physical headquarters to resources hosted within an Azure Virtual Network (VNet). The network engineers have specified two main requirements: a primary path that utilizes a dedicated private circuit for low latency without using the public internet, and a secondary backup path that secures data using encryption while routing over the public internet. Which two Azure services should the corporation deploy to satisfy these design requirements? (Select two.)

  1. Azure ExpressRouteAnswer
  2. Azure VPN GatewayAnswer
  3. C
    Azure Virtual Network (VNet) peering
  4. D
    An Azure ExpressRoute connection configured to route traffic over the public internet

Answer

Azure ExpressRoute and Azure VPN Gateway are the two required services.
To satisfy the requirements, the organization must implement two distinct connectivity paths. The primary requirement for a private, dedicated connection is met by deploying Azure ExpressRoute. The backup requirement for an encrypted, cost-effective connection over the public internet is met by deploying Azure VPN Gateway.

Step-by-Step Solution

1
Analyze the primary connection requirement: a dedicated private circuit that bypasses the public internet.
Identify Azure ExpressRoute as the service that fulfills this criteria by offering dedicated, private connectivity.
ExpressRoute provides private connections to Azure cloud services without traversing the public internet.
2
Analyze the secondary connection requirement: a cost-effective backup connection that encrypts data over the public internet.
Identify Azure VPN Gateway as the service that fulfills this criteria.
VPN Gateway uses the public internet to transmit encrypted traffic securely at a lower cost compared to ExpressRoute.
