Google Cloud Professional Cloud Network Engineer — Question 238

You are setting up a Dedicated Interconnect connection from your organization’s on-premises data center in Frankfurt, Germany, towards the europe-west3 region, which is also in the Frankfurt metropolitan area. The AI team lead expressed their concern regarding connectivity to the europe-west4 region because their team wants to use Google Cloud TPUs for their workloads. You need to ensure that low latency network connectivity is established for this team’s workloads. You want to minimize costs and operational overhead. What should you do?

Answer options

• A. Set up the Dedicated Interconnect connection towards the europe-west4 region instead of the europe-west3 region.
• B. Set up an additional Partner Interconnect connection between your data center and the europe-west4 region.
• C. Set up a remote VLAN attachment to the europe-west4 region on the Dedicated Interconnect connection.
• D. Use Cloud VPN instead of Dedicated Interconnect to send traffic over the internet.

Correct answer: C

Explanation

The correct answer is C because setting up a remote VLAN attachment on the Dedicated Interconnect connection allows for direct low-latency access to the europe-west4 region, ensuring optimal performance for the AI team's TPU workloads. Option A is incorrect as it doesn't address the need for connectivity to europe-west4 specifically. Option B involves additional costs and complexity with a Partner Interconnect, which is not necessary. Option D, using Cloud VPN, would introduce higher latency due to internet traffic, which is not ideal for TPU workloads.
