Which AWS service will meet these requirements?

Explanations:

AWS DataSync is used for data transfer over the internet or AWS Direct Connect, making it unsuitable for this requirement since the company does not want to use an internet connection.

Amazon Connect is a cloud-based contact center service and is not related to data migration. It does not facilitate the transfer of large datasets.

AWS Snowmobile is a petabyte-scale data transfer service that uses a secure, physical truck to transfer large amounts of data directly to AWS without relying on an internet connection.

AWS Direct Connect provides a dedicated network connection from on-premises to AWS but does not facilitate the physical transfer of petabytes of data without an internet connection.
