QUESTION 45
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.
