Two peered VPCs (projects A and B) each have VMs across 4 zones. To get a Network Intelligence Center packet-loss metric for flows from VPC A to VPC B with at least 90% confidence, what must you do?

Correct answer: Ensure each zone in both VPCs has at least 10 compute instances; view the metric in Project B..
Why this is the answer
Network Intelligence Center's connectivity tests require a minimum of 10 compute instances per zone in both the source and destination VPCs to generate packet-loss metrics with at least 90% confidence. This threshold ensures sufficient traffic for accurate sampling and statistical analysis. When analyzing traffic between peered VPCs, the metrics are typically viewed from the destination project's perspective. Therefore, to see packet loss for flows from VPC A to VPC B, you would view the metric in Project B. The options with 9 instances are incorrect because they don't meet the minimum requirement for 90% confidence.
