Question

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?

Options

  • AProvision a Partner Interconnect through your ISP.
  • BProvision a Dedicated Interconnect instead of a VPN.
  • CCreate multiple VPN tunnels to account for the packet losses, and increase bandwidth using
  • DUse network compression over your VPN to increase the amount of data you can send over your
