Google Cloud Professional Cloud Architect — Question 254

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:
✑ as close to 100% system availability as possible
✑ 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. 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

Correct answer: A

Explanation

The correct answer is A because an HA Cloud VPN gateway provides high availability, ensuring close to 100% uptime, while the two tunnels offer redundancy. Options B and C involve Classic Cloud VPN gateways, which do not provide the same level of availability as HA, and D does not meet the redundancy requirement, making it less suitable for the business's needs.
