Google Professional Cloud Network Engineer Question 126
Single answerGoogle Cloud PlatformYour organization needs to establish a private connection between your on-premises network and Google Cloud to meet low-latency requirements for data transfer. The organization is located in a region where Google does not provide a dedicated edge location, but there are several third-party ISPs that are Google-approved Verified Peering Providers. Which connectivity option should you choose?
- A
Use Direct Peering to establish a private connection with Google Cloud.
- B
Use a Verified Peering Provider to establish a private connection through a third-party ISP.
- C
Use Cloud Interconnect to directly connect your on-premises network to Google.
- D
Use a VPN connection as it provides similar capabilities to Direct Peering.
Show answer and explanation
Correct answer: B
Explanation
When choosing between Direct Peering and a Verified Peering Provider, the availability of a Google edge location is a key factor. Direct Peering requires a Google edge location, while Verified Peering Providers allow connectivity through third-party ISPs in areas where Google does not have a direct presence. In this scenario, using a Verified Peering Provider is the best option as it meets the organization's low-latency requirements and addresses the lack of a Google edge location.
- A. Incorrect.
Direct Peering requires a Google edge location to be available in your region. Since the scenario specifies that no Google edge location is available, this is not a feasible option.
- B. Correct.
Verified Peering Providers are third-party ISPs approved by Google, and they allow you to establish connectivity in regions where Google does not have a direct presence. This makes it the correct choice in this scenario.
- C. Incorrect.
Cloud Interconnect is not relevant here because the scenario specifically discusses Direct Peering or Verified Peering Provider as options. Cloud Interconnect requires a partner or dedicated connection, which is unrelated to the peering options described.
- D. Incorrect.
While VPN connections can provide connectivity, they are not equivalent to Direct Peering in terms of low latency and private connectivity. This option does not meet the stated requirement for low latency.
