Selected Answer: D
HA VPN provides high availability by using two tunnels that terminate on two separate Google Cloud VPN gateways. BGP enables dynamic routing between the on-premises network and Google Cloud, allowing for automatic failover in case one VPN gateway or tunnel becomes unavailable. This ensures continuous connectivity between the two VPCs with minimal downtime. Options A, B, and C use Classic VPN, which is not recommended for new deployments as it lacks certain features such as high availability and dynamic routing. Therefore, option D is the most suitable choice for ensuring maximum availability and following Google-recommended practices.
