Connect VNets in Different Regions using IPsec/IKE S2S VPN Tunnel

Correct Answer: A

Connecting a virtual network (VNet) to another VNet is similar to connecting a VNet to an on-premises site location.

In both types of connectivity, a VPN gateway is used to provide a secure tunnel using IPsec/IKE.The Virtual networks that you connect can be: in the different or same subscriptions.

in the different or same regions.

in the different or same deployment models.

Yes, you can connect two virtual networks (VNets) present in different regions using IPsec/IKE S2S VPN Tunnel in Microsoft Azure.

An Azure Virtual Network (VNet) is a logically isolated network within the Azure cloud infrastructure. VNet allows customers to securely connect Azure resources and on-premises resources to each other.

Azure VPN Gateway provides a secure, cross-premises connection between the customer's on-premises infrastructure and Azure. The VPN Gateway supports two types of VPN connections: Site-to-Site (S2S) and Point-to-Site (P2S).

Site-to-Site (S2S) VPN connection creates a secure connection between on-premises infrastructure and Azure Virtual Networks (VNets). S2S VPN connection is established between two VPN devices. In Azure, the VPN Gateway serves as the VPN device.

To establish a Site-to-Site VPN connection between two virtual networks (VNets) in different regions, you need to create a VPN Gateway for each region. The Azure VPN Gateway requires two virtual network gateways, each for a separate VNet, to be created to connect both the VNets. Then, configure the VPN Gateway with the required settings for the VPN connection, including the IPsec/IKE protocol, and shared key. Finally, configure the local network gateway with the required settings to establish the connection between the VPN gateways.

In summary, Yes, it is possible to connect two virtual networks (VNets) present in different regions using IPsec/IKE S2S VPN Tunnel in Microsoft Azure.
