Your company is moving 75 TB of data into Google Cloud. You want to use Cloud Storage and follow Google-recommended practices. What should you do?

For transferring 75 TB of data, a Transfer Appliance is the most efficient and recommended method. It's designed for petabyte-scale data transfers, overcoming network bandwidth limitations. The data is encrypted on the appliance, and a Transfer Appliance Rehydrator is specifically used in Google Cloud to decrypt and ingest this data into Cloud Storage, ensuring data integrity and security. Using Cloud Dataprep for decryption is incorrect as it's a data preparation service, not a decryption tool for Transfer Appliance data. While gsutil can transfer data, it's not practical for 75 TB due to potential network bottlenecks and transfer times, making it less suitable than a Transfer Appliance. Streaming transfers with gsutil are generally for smaller, real-time data, not bulk historical transfers of this magnitude.
