Difficulty: EasyAzure Virtual Networks, ExpressRoute, and VPN Gateway

A company plans to connect its local office to an Azure virtual network. The connection must be secure, encrypted, and established quickly over the public internet. Which Azure service should the company use?

  1. Azure VPN GatewayAnswer
  2. B
    Azure ExpressRoute
  3. C
    Azure Virtual Network peering
  4. D
    Azure Application Gateway

Answer

Azure VPN Gateway
Azure VPN Gateway is correct because it sends encrypted network traffic between an Azure virtual network and an on-premises location over the public internet, which allows for quick setup and secure communication.

Step-by-Step Solution

1
Identify the key requirements from the scenario: on-premises to Azure connectivity, encrypted transmission, quick setup, and routing over the public internet.
Recognize that the solution must be a hybrid connectivity service that traverses the public internet.
This helps eliminate internal-only services and those requiring dedicated physical lines.
2
Evaluate the remaining options to find the service that uses the public internet.
Determine that Azure VPN Gateway meets all the criteria, whereas ExpressRoute does not use the public internet.
VPN Gateway encrypts and routes traffic over the public internet, matching the quick and secure requirement.

Key Concept

Azure VPN Gateway establishes secure, encrypted connections over the public internet, while ExpressRoute uses private, dedicated connections.
