The correct answer is 'Snowball', a physical data transport solution that helps transfer massive amounts of data into and out of the cloud platform without depending on the internet, reducing data transfer time and costs. 'Direct Connect' establishes a dedicated network connection but does not address the issue of physically transferring large data sets. The 'Management Console' is an interface for managing cloud services rather than a data transfer tool. 'EC2' instances run workloads in the cloud rather than facilitating data transfer, and while 'S3' is used for data storage, it doesn't represent a physical transfer device. 'CloudFormation' is used for infrastructure as code, not for data transfer.
