Your software team is developing an on-premises web application that requires direct connectivity to Compute Engine Instances in GCP using the RFC 1918 address space. You want to choose a connectivity solution from your on-premises environment to GCP, given these specifications:
Your ISP is a Google Partner Interconnect provider.
Your on-premises VPN device’s internet uplink and downlink speeds are 10 Gbps.
A test VPN connection between your on-premises gateway and GCP is performing at a maximum speed of 500 Mbps due to packet losses. Most of the data transfer will be from GCP to the on-premises environment.
The application can burst up to 1.5 Gbps during peak transfers over the Interconnect. Cost and the complexity of the solution should be minimal.
How should you provision the connectivity solution?
A. Provision a Partner Interconnect through your ISP.
B. Provision a Dedicated Interconnect instead of a VPN.
C. Create multiple VPN tunnels to account for the packet losses, and increase bandwidth using ECMP.
D. Use network compression over your VPN to increase the amount of data you can send over your VPN.

“C” is not right.
Dedicated Interconnect, Partner Interconnect, Direct Peering, and Carrier Peering can all help you optimize egress traffic from your VPC network and reduce your egress costs. Cloud VPN by itself does not reduce egress costs.

“A” should be better.
A. pkt loss is due to internet quality, need private, and partner is much cheaper than dedicated as less than 10G.
C is right https://cloud.google.com/solutions/building-high-throughput-vpns
A. would be the right answer . ECMP VPN does not benefit for single session and Dedicated interconnect is reasonable for 10Gbps or more needs.
