Answer: Leverage Transfer Appliance to physically transport the data to Google Cloud Storage
**Correct Answer: C. Leverage Transfer Appliance to physically transport the data to Google Cloud Storage.** Transfer Appliance is the optimal solution for migrating 2 PB of data within six months under a 20 Mb/sec network constraint. It's a physical device provided by Google Cloud for secure, large-scale data transfers. You load your data onto the appliance, then ship it to a Google data center for fast and secure uploading to Cloud Storage. **Why other options are less suitable:** - **A.** While compressing data can reduce transfer size, it doesn't overcome the network limitation and may introduce additional processing time. - **B.** This method still relies on the constrained network bandwidth, making it impractical for the given data volume and timeframe. - **D.** Although these tools can manage bandwidth usage, they're not as efficient or reliable for transferring such a large volume of data within the specified period.

You have 2 petabytes of historical data stored on-premises that needs to be migrated to Google Cloud Storage within six months. Given your outbound network capacity is limited to 20 Mb/sec, what is the most efficient method to achieve this migration?
A
Utilize gsutil cp with compression to reduce the data size before uploading to Cloud Storage
B
Generate a private URL for the data and employ Storage Transfer Service for the migration
C
Leverage Transfer Appliance to physically transport the data to Google Cloud Storage
D
Apply trickle or ionice alongside gsutil cp to restrict bandwidth usage below 20 Mb/sec, avoiding impact on production traffic
