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.
Layer-2 encryption device

B.
AES encryption directive

C.
Inline encryption device

D.
