You have applications deployed in both the us-west1 and us-east1 regions. Your goal is to establish a highly available VPN with 99.99% uptime to connect your project's applications to your partner's cloud services (also located in us-west1 and us-east1), while minimizing infrastructure overhead. What is the simplest solution to implement?

What is the simplest solution to implement?
Explanation:
To achieve a highly available VPN with 99.99% availability between your applications and your partner's services in the us-west1 and us-east1 regions, the simplest and most effective solution is to deploy HA VPN gateways and Cloud Routers in each region for both your VPC and your partner's VPC. This setup ensures redundancy within each region through HA VPN's dual tunnels and enables cross-region failover by utilizing global dynamic routing. This approach meets the required SLA and minimizes infrastructure complexity by leveraging Google Cloud's managed services. Options B and C introduce OpenVPN, which does not meet the 99.99% SLA requirement, and Option D lacks the necessary redundancy by only deploying in one region. Therefore, Option A is the correct choice.
