Answer: Use the Storage Transfer Service after establishing a Cloud Interconnect connection between the on-premises data center and Google Cloud
To efficiently transfer a large volume of data (1 PB) within a short timeframe, it's advisable to utilize a dedicated network connection such as Cloud Interconnect. This method offers higher bandwidth and lower latency than public internet connections. The Storage Transfer Service, compatible with Cloud Interconnect, facilitates secure and reliable data transfers between on-premises and cloud storage. Alternatives like using a Transfer Appliance (Option D) involve manual data handling, potentially extending the transfer duration. Similarly, employing gcloud compute scp jobs (Option A) might not be as reliable or swift. Breaking down the data into smaller batches (Option C) complicates the migration process and may not satisfy the rapid transfer requirement.
