Correct answer: Enable parallel composite uploads using gsutil on the file transfer..
Why this is the answer
Enabling parallel composite uploads with gsutil is the most efficient method for transferring a large file (32 GB) over a high-bandwidth link (1 Gbps WAN). This feature splits the file into smaller chunks, uploads them concurrently, and then reassembles them in Cloud Storage, significantly improving transfer speed by maximizing bandwidth utilization. Using the GCP Console for large files is generally less efficient than gsutil and doesn't offer advanced optimization features like parallel composite uploads. Decreasing the TCP window size would hinder, not help, throughput on a high-bandwidth link. Changing the storage class from Nearline to Multi-Regional affects data availability and pricing, not the upload mechanism or speed.
