Answer: Use Transfer Appliance to copy the data to Cloud Storage
The correct answer is A. Transfer Appliance is most suitable for transferring large volumes of data such as 2 PB, especially when network bandwidth is constrained. Using Transfer Appliance allows you to physically transfer the data much faster without being limited by the slow network speed. Other options like using gsutil cp or Storage Transfer Service would not be feasible within the given time frame, as they would take significantly longer due to the network limitations.

As a Google Professional Data Engineer, you are tasked with transferring 2 Petabytes (PB) of historical data from an on-premises storage system to Google Cloud Storage. This data migration must be completed within a six-month timeframe. However, your data transfer speed is limited by an outbound network capacity of 20 Megabits per second (Mb/sec). What strategy should you employ to efficiently migrate this data to Cloud Storage?
A
Use Transfer Appliance to copy the data to Cloud Storage
B
Use gsutil cp 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
