Correct answer: Request Transfer Appliances, export the data to the appliances, and return the appliances to Google for upload..
Why this is the answer
Transfer Appliance is the most suitable solution for transferring 1 PB of data over a 1 Gbps link within a month. A 1 Gbps link would take approximately 93 days to transfer 1 PB, exceeding the one-month deadline. Transfer Appliance physically ships your data to Google, bypassing network limitations. Storage Transfer Service is for online transfers and would be too slow given the data volume and link speed. While multi-threaded transfers can optimize network usage, they cannot overcome the fundamental bandwidth limitation for such a large dataset within the given timeframe. Exporting to a USB device is impractical for 1 PB of data due to capacity limitations and the manual effort involved.
