Google Cloud Professional Cloud Architect — Question 240

You are deploying an application to Google Cloud. The application is part of a system. The application in Google Cloud must communicate over a private network with applications in a non-Google Cloud environment. The expected average throughput is 200 kbps. The business requires:

• 99.99% system availability
• cost optimization

You need to design the connectivity between the locations to meet the business requirements. What should you provision?

Answer options

• A. An HA Cloud VPN gateway connected with two tunnels to an on-premises VPN gateway.
• B. A Classic Cloud VPN gateway connected with two tunnels to an on-premises VPN gateway.
• 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 Classic Cloud VPN gateway connected with one tunnel to an on-premises VPN gateway.

Correct answer: A

Explanation

The correct answer is A, as an HA Cloud VPN gateway with two tunnels provides high availability and redundancy, which is essential to meet the 99.99% availability requirement. Options B and D do not offer the necessary high availability, while option C, although robust, introduces unnecessary complexity and cost compared to option A.
