Google Cloud Professional Cloud Network Engineer — Question 77
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?
Answer options
- A. Direct Peering
- B. Dedicated Interconnect
- C. Partner Interconnect with a layer 2 partner
- D. Partner Interconnect with a layer 3 partner
Correct answer: D
Explanation
The correct answer is D, Partner Interconnect with a layer 3 partner, as it allows for connections without the need for BGP on your on-premises router while connecting through a partner. Option A, Direct Peering, requires meeting at a POP location, which is not feasible here. Option B, Dedicated Interconnect, also mandates a direct connection to a Google facility, which is not possible in this case. Option C, Partner Interconnect with a layer 2 partner, would still require BGP configuration, which your router cannot support.
