A customer has an existing EMC NetWorker backup group consisting of one file server. The file
server has dual quad-core 2.9-GHz CPUs, 16 GB of RAM, and a single file system with a total of 6
TB of data. Due to a recent loss of backup tapes during shipment, the customer needs to encrypt
the backups.
The customer wants to prevent any possibility of backup data being intercepted during the
transmission of backup data from the client to the NetWorker storage node. In addition, they want
to minimize the change to their file server hardware and minimize operational changes.

Which method meets the customer’s requirements?

A.
AES encryption directive

B.
Inline encryption device

C.
Tape drive hardware encryption

D.
Layer-2 encryption device
