PCNE Implementing Hybrid Interconnectivity Practice Question
An organization wants to migrate legacy on-premises applications to Google Cloud but must maintain low-latency connectivity for real-time data synchronization. The on-premises data center is in a colocation facility that is not directly served by Google Cloud. Which hybrid connectivity option is most cost-effective while meeting the latency requirement?
⚠ Common exam trap
Google Cloud often tests the misconception that Direct Peering or Cloud VPN can meet low-latency requirements, but the trap here is that only Partner Interconnect or Dedicated Interconnect provide SLA-backed, low-latency connectivity, and Partner Interconnect is the correct choice when the on-premises site is not in a Google Cloud colocation facility.

Correct answer & explanation
✓
Partner Interconnect
Partner Interconnect is the most cost-effective option because it provides a dedicated, low-latency connection through a supported service provider that can extend connectivity from the colocation facility to a Google Cloud region. Unlike Dedicated Interconnect, it does not require physical cross-connects in a Google Cloud colocation facility, making it ideal when the on-premises site is not directly served by Google Cloud. It meets the real-time synchronization latency requirement by offering a reliable, high-bandwidth connection with SLA-backed uptime.
