Answer: Peer the two VPCs. Configure VPC Network Peering to export custom routes from Sales and import custom routes on Finance's VPC network. Use Cloud Router’s custom route advertisements to announce the peered VPC network ranges to the on-premises locations.
The correct approach involves peering the two VPCs and configuring VPC Network Peering to export custom routes from the Sales department's VPC and import them into the Finance department's VPC. Additionally, using Cloud Router’s custom route advertisements to announce the peered VPC network ranges to the on-premises locations ensures that all routes between the Finance department and on-premises locations are propagated correctly without allowing internet access from on-premises locations to flow through Google Cloud. This is accurately described in option D.

Your company has two separate VPC networks (Sales and Finance) in a single region. The Sales VPC is already connected to on-premises via HA VPN, with non-overlapping subnet ranges. You want to peer both VPCs to share the same HA VPN tunnels for on-premises connectivity while using Cloud NAT for internet access from Google Cloud workloads. On-premises internet traffic should not route through Google Cloud. All routes between Finance and on-premises must be propagated. What steps should you take?
A
Peer the two VPCs, and use the default configuration for the Cloud Routers.
B
Peer the two VPCs, and use Cloud Router’s custom route advertisements to announce the peered VPC network ranges to the on-premises locations.
C
Peer the two VPCs. Configure VPC Network Peering to export custom routes from Sales and import custom routes on Finance's VPC network. Use Cloud Router’s custom route advertisements to announce a default route to the on-premises locations.
D
Peer the two VPCs. Configure VPC Network Peering to export custom routes from Sales and import custom routes on Finance's VPC network. Use Cloud Router’s custom route advertisements to announce the peered VPC network ranges to the on-premises locations.
