Answer: Set up Cloud VPN between the on-premises network and Google Cloud.
**B is correct** because setting up Cloud VPN between the on-premises network and Google Cloud enables secure, private communication between on-premises workloads and GCP workloads using private IPs. Cloud VPN establishes an encrypted IPsec tunnel over the public internet, ensuring secure and private communication during the migration process. - **A is incorrect** because VPC network peering is designed for sharing VPC IP ranges between separate GCP VPCs, not for connecting on-premises networks. - **C is incorrect** because Shared VPC allows multiple projects to share a common set of VPC resources within GCP, but does not facilitate communication with on-premises networks. - **D is incorrect** as using public IP addresses for bastion hosts is not secure for private communication between on-premises and GCP workloads.
