B . pvcreate /dev/sdc
C . mkfs . ext4 /dev/mapper/LUKSCJ001 – L ENCRYPTED
D . umount / dev/ sdc
E . fdisk /dev/sdc
F . mkfs . vfat /dev/mapper/LUKS0001 ― L ENCRYPTED
G . wipefs ―a/dev/sdbl
H . cryptsetup IuksFormat /dev/ sdcl

Answer: C D H

Explanation:

To enable LUKS on a USB storage device with an ext4 filesystem format, the administrator needs to perform the following steps:

Unmount the device if it is mounted using umount /dev/sdc (D)

Create a partition table on the device using fdisk /dev/sdc (E)

Format the partition with LUKS encryption using cryptsetup luksFormat /dev/sdc1 (H)

Open the encrypted partition using cryptsetup luksOpen /dev/sdc1 LUKS0001

Create an ext4 filesystem on the encrypted partition using mkfs.ext4 /dev/mapper/LUKS0001 ©

Mount the encrypted partition using mount /dev/mapper/LUKS0001 /mnt References:
