Answer: An HA Cloud VPN gateway connected with two tunnels to an on-premises VPN gateway
The correct answer is A. An HA Cloud VPN gateway connected with two tunnels to an on-premises VPN gateway can provide high availability with an SLA of 99.99%. This configuration ensures redundancy by using two tunnels, which can each connect to different external IP addresses on the on-premises VPN gateway. This setup meets the business requirements of close to 100% system availability and cost optimization. Option B, using two Classic Cloud VPN gateways, is more complex to manage and less cost-effective. Option C, while providing full redundancy, is more expensive and not necessary for the given requirements. Option D does not provide the necessary level of high availability.

You are deploying a critical application to Google Cloud. This application is part of a larger, interconnected system and needs to communicate over a private network with other applications hosted in a non-Google Cloud environment, such as on-premises data centers. Given the expected average throughput of 200 kbps and the need for high availability and cost optimization, how should you design the connectivity to ensure secure and reliable communication between Google Cloud and the non-Google Cloud environment?
A
An HA Cloud VPN gateway connected with two tunnels to an on-premises VPN gateway
B
Two Classic Cloud VPN gateways connected to two on-premises VPN gateways. Configure each Classic Cloud VPN gateway to have two tunnels, each connected to different on-premises VPN gateways
C
Two HA Cloud VPN gateways connected to two on-premises VPN gateways. Configure each HA Cloud VPN gateway to have two tunnels, each connected to different on-premises VPN gateways
D
A single Cloud VPN gateway connected to an on-premises VPN gateway
