Google Cloud Professional Data Engineer — Question 106

You need to move 2 PB of historical data from an on-premises storage appliance to Cloud Storage within six months, and your outbound network capacity is constrained to 20 Mb/sec. How should you migrate this data to Cloud Storage?

Answer options

• A. Use Transfer Appliance to copy the data to Cloud Storage
• B. Use gsutil cp ג€"J to compress the content being uploaded to Cloud Storage
• C. Create a private URL for the historical data, and then use Storage Transfer Service to copy the data to Cloud Storage
• D. Use trickle or ionice along with gsutil cp to limit the amount of bandwidth gsutil utilizes to less than 20 Mb/sec so it does not interfere with the production traffic

Correct answer: A

Explanation

The correct answer is A because Transfer Appliance is specifically designed for large data transfers and can handle 2 PB efficiently. Other options, while potentially helpful, do not effectively address the large volume of data within the given bandwidth constraints and time frame, making them less viable solutions.
