Your company is building a new architecture to support its data-centric business focus. You are responsible for setting up the network. Your company's mobile and web-facing applications will be deployed on-premises, and all data analysis will be conducted in GCP. The plan is to process and load 7 years of archived .csv files totaling 900 TB of data and then continue loading 10 TB of data daily. You currently have an existing 100-MB internet connection. What actions will meet your company's needs?

Correct answer: Lease a Transfer Appliance, upload archived files to it, and send it to Google to transfer archived data to Cloud Storage. Establish a connection with Google using a Dedicated Interconnect or Direct Peering connection and use it to upload files daily..
Why this is the answer
The correct option addresses both the large initial data transfer and the ongoing daily transfers efficiently and securely. Transfer Appliance is ideal for the initial 900 TB archive, as it bypasses the limitations of the existing 100-MB internet connection for bulk data. For the ongoing 10 TB daily transfers, a Dedicated Interconnect or Direct Peering connection provides a high-bandwidth, low-latency, and secure private connection to GCP, which is crucial for data-centric operations and significantly more reliable and performant than public internet options. Compressing and uploading all data via the existing 100-MB internet connection (first incorrect option) would be prohibitively slow for 900 TB of archived data and potentially too slow for daily 10 TB transfers, even with compression. Using a Cloud VPN Tunnel over the public internet (third and fourth incorrect options) for daily 10 TB transfers would introduce latency, potential bandwidth bottlenecks, and reliance on the public internet, which is less secure and reliable than a private interconnect for critical data operations. The third option also incorrectly suggests compressing and uploading daily files with gsutil -m over a VPN tunnel, which is inefficient for 10 TB daily.
