Difficulty: EasyAzure Virtual Networks, ExpressRoute, and VPN Gateway

A small business wants to connect its local office server room to an Azure Virtual Network. The connection must use the business's existing public internet connection to keep setup and monthly costs low. Which Azure service should the business deploy to establish this connection?

  1. Azure VPN GatewayAnswer
  2. B
    Azure ExpressRoute
  3. C
    Azure Arc
  4. D
    Azure Policy

Answer

Azure VPN Gateway
Azure VPN Gateway is the correct service because it sends encrypted traffic between an Azure Virtual Network and an on-premises location over the public internet, satisfying the low-cost and existing internet usage requirements.

Step-by-Step Solution

1
Analyze the connection requirement
The business needs to connect an on-premises location to an Azure Virtual Network.
Identifying the source and destination of the network connection helps narrow down the service options.
2
Evaluate the budget and path constraints
The solution must use the existing public internet connection to keep costs low.
This eliminates ExpressRoute, which requires a private, dedicated physical connection and does not use the public internet.
3
Select the appropriate hybrid networking service
Azure VPN Gateway is selected as it creates an encrypted tunnel over the public internet.
It directly satisfies the requirement for a cost-effective, internet-based connection between on-premises and Azure.

Key Concept

Establishing secure, cost-effective hybrid connectivity to Azure Virtual Networks using the public internet.
