Answer: Configure a Cloud Dedicated Interconnect connection between the on-premises environment and Google Cloud.
The question requires enabling communication between Compute Engine instances and an on-premises service with high throughput via internal IPs while minimizing latency. Cloud Dedicated Interconnect (Option D) is the optimal choice because it provides a direct, private physical connection to Google Cloud, ensuring high throughput (up to 10 Gbps or 100 Gbps per connection) and low latency by bypassing the public internet. It supports internal IP communication natively. In contrast, Cloud VPN (Option C) uses public internet tunnels, which introduce higher latency and lower reliability, making it unsuitable for high-throughput needs. OpenVPN (Option A) is a software-based VPN with similar limitations. Direct Peering (Option B) is for public IP traffic and does not support internal IPs. The community discussion strongly favors Option D (98% consensus), with high upvotes for comments emphasizing its alignment with high-throughput and low-latency requirements.
