Answer: Use an IP range on Google Cloud that does not overlap with the range you use on-premises
The correct answer is C: 'Use an IP range on Google Cloud that does not overlap with the range you use on-premises.' This is important because when using Cloud VPN to connect your on-premises systems with Google Cloud, overlapping IP ranges can cause routing conflicts and make it difficult to manage network traffic effectively. According to Google Cloud documentation, both primary and secondary IP ranges in VPC networks must not overlap with any on-premises IP ranges to avoid such issues. Ensuring non-overlapping IP ranges will maintain connectivity and avoid conflicts during your phased migration.
