You need to migrate the dataset to Azure

A company has a very large dataset that includes sensitive information. The dataset is over 30 TB in size.
You have a standard business-class ISP internet connection that is rated at 100 megabits/second.
You have 10 4-TB hard drives that are approved to work with the Azure Import/Export Service.
You need to migrate the dataset to Azure. The solution must meet the following requirements:
The dataset must be transmitted securely to Azure.
Network bandwidth must not increase.
Hardware costs must be minimized.What should you do?

A.
Prepare the drives with the Azure Import/Export tool and then create the import job. Ship the drives to
Microsoft via a supported carrier service.

B.
Create an export job and then encrypt the data on the drives by using the Advanced Encryption Standard
(AES). Create a destination Blob to store the export data.

C.
Create an import job and then encrypt the data on the drives by using the Advanced Encryption Standard
(AES). Create a destination Blob to store the import data.

D.
Prepare the drives by using Sysprep.exe and then create the import job. Ship the drives to Microsoft via a
supported carrier service.

Explanation:
You can use the Microsoft Azure Import/Export service to transfer large amounts of file data to Azure Blob
storage in situations where uploading over the network is prohibitively expensive or not feasible.
