Google Cloud Professional Cloud Architect — Question 113

Your company has an application running on multiple Compute Engine instances. You need to ensure that the application can communicate with an on-premises service that requires high throughput via internal IPs, while minimizing latency. What should you do?

Answer options

• A. Use OpenVPN to configure a VPN tunnel between the on-premises environment and Google Cloud.
• B. Configure a direct peering connection between the on-premises environment and Google Cloud.
• C. Use Cloud VPN to configure a VPN tunnel between the on-premises environment and Google Cloud.
• D. Configure a Cloud Dedicated Interconnect connection between the on-premises environment and Google Cloud.

Correct answer: D

Explanation

The correct answer is D because Cloud Dedicated Interconnect provides a direct physical connection to Google Cloud, ensuring high throughput and low latency, which is essential for the application's communication needs. Options A and C involve VPNs, which can introduce additional latency and are not optimized for high throughput. Option B, while it provides a direct connection, does not guarantee the same level of performance as a Dedicated Interconnect.
