You don't need to deploy VPN to two regions, because of its global nature. C is correct
Option C: Create a global VPN gateway and establish VPN tunnels from each region to the on-premises peer gateway. This suggests that a single global VPN gateway manages the tunnels from both regions. Option D: Deploy a VPN gateway in each region and ensure that each region has at least one VPN tunnel to the on-premises peer gateway. This indicates that each region has its own VPN gateway. >Option D ensures that there is a VPN gateway in each region, providing greater redundancy. If a gateway in one region fails, the gateway in the other region remains operational.
Global Cloud VPN Gateway: This feature allows for the creation of a single VPN gateway that can serve multiple regions within the same VPC network. By creating a global VPN gateway, you can efficiently manage VPN connections from all regions of your VPC to your on-premises network. Simplicity and Efficiency: Using a global gateway simplifies the configuration and management of VPN connections as opposed to maintaining separate regional VPN gateways. It centralizes the VPN endpoint on the Google Cloud side, reducing the complexity of the network setup. Reliable and Secure Communication: The global Cloud VPN Gateway allows for secure, encrypted tunnels between Google Cloud and the on-premises network, ensuring that the application’s inter-regional and on-premises communications are secure.
