Google Cloud Professional Cloud Architect — Question 230

A financial services company is decommissioning one of its on-premises data centers. As part of this initiative, the company needs to perform a one-time migration of 500 ТВ of historical transaction archives to a Cloud Storage bucket for long-term retention. The data center’s internet egress is 1 Gbps, which is shared with critical business operations. You must complete the secure data transfer within a 60-day window to meet the decommissioning deadline. What should you do?

Answer options

• A. Provision a Partner Interconnect connection with a 10 Gbps capacity to accelerate the data transfer, and then use Storage Transfer Service.
• B. Write a script that uses the gcloud storage cp --parallel command to upload the data in chunks over the public internet during off-peak hours.
• C. Use Storage Transfer Service to create an agent-based transfer job that moves the data from the on-premises file servers directly to the Cloud Storage bucket.
• D. Order a Transfer Appliance, copy the data to the appliance using your high-speed local network, and ship it back to Google to upload the data into your Cloud Storage bucket.

Correct answer: D

Explanation

The correct answer is D because using a Transfer Appliance allows for a secure, efficient transfer of large volumes of data without relying on limited internet bandwidth. Options A and C do not provide a feasible solution given the egress limitations and the need for a quick transfer, while option B would be too slow and disruptive to critical operations due to the internet bandwidth constraints.
