Correct answer: An HA Cloud VPN gateway with two tunnels to the on-premises VPN gateway..
Why this is the answer
An HA Cloud VPN gateway with two tunnels to the on-premises VPN gateway is the correct choice. HA VPN provides 99.99% availability, meeting the requirement. Two tunnels ensure redundancy and failover, contributing to the high availability. The throughput of ~200 kbps is well within VPN capabilities, and VPN is generally cost-effective for this level of throughput compared to dedicated interconnects. Classic Cloud VPN gateways offer 99.9% availability, which does not meet the 99.99% requirement. Two HA Cloud VPN gateways paired with two on-prem VPN gateways is an overly complex and expensive solution for the given throughput and availability needs. A Classic Cloud VPN gateway with one tunnel does not meet the availability requirement and lacks redundancy.
