Explanation:
The correct answer is A. The gsutil rsync command allows you to synchronize files between on-premises servers and Google Cloud Storage. Since the security rules don't allow access from external IPs to the on-premises resources, using tools like Dataflow, which operate from the cloud, is not an option. By executing gsutil rsync from the on-premises servers, you can push the data from the on-premises network to Google Cloud Storage, which is allowed by the security rules. Option A is the simplest and most secure method under these constraints.

Your company is planning to move its historical data to Google Cloud Storage for long-term storage and analysis. However, the security policies in place do not permit access to the on-premises resources from external IP addresses. Once the initial upload is complete, the organization intends to update this storage daily with new data generated from on-premises applications. What steps should the company take to achieve this, considering the need to maintain compliance with security protocols?
A
Execute gsutil rsync from the on-premises servers.
B
Use Dataflow and write the data to Cloud Storage.
C
Write a job template in Dataproc to perform the data transfer.
D
Install an FTP server on a Compute Engine VM to receive the files and move them to Cloud Storage.
