Topic 1 Question 56
You want to use Cloud Interconnect to connect your on-premises network to a GCP VPC. You cannot meet Google at one of its point-of-presence (POP) locations, and your on-premises router cannot run a Border Gateway Protocol (BGP) configuration. Which connectivity model should you use?

The answer is D. https://cloud.google.com/network-connectivity/docs/interconnect/concepts/partner-overview For Layer 3 connections, your service provider establishes a BGP session between your Cloud Routers and their edge routers for each VLAN attachment. You don't need to configure BGP on your on-premises router. Google and your service provider automatically set the correct configurations.
👍 26porsak2021/02/13The answer is D: Partner interconnect is of two types layer 2 and layer 3 With Layer 2 Interconnect you MUST configure BGP on your on-prem router With Layer 3: router configuration and peers are fully automated. Hence the question "Your on-prem router cannot run a BGP protocol configuration"
👍 11ArizonaClassics2021/03/03D is the answer - For layer 2 connections, you must configure and establish a BGP session between your Cloud Routers and on-premises routers for each VLAN attachment that you create. The BGP configuration information is provided by the VLAN attachment after your service provider has configured it. For a Layer 3 connection BGP is configured from your partner to the Cloud Router in GCP, no need for BGP on-premise.
