LFCA · Question #26

A supervisor instructs an IT associate to encrypt all data on a particular partition on a Linux database host. What open source technology would be used to encrypt the data?

The correct answer is B. LUKS. To encrypt an entire partition on a Linux system, LUKS (Linux Unified Key Setup) is the standard open-source technology. It provides a disk encryption specification that is widely supported across Linux distributions for full disk or partition encryption.

Why each option

To encrypt an entire partition on a Linux system, LUKS (Linux Unified Key Setup) is the standard open-source technology. It provides a disk encryption specification that is widely supported across Linux distributions for full disk or partition encryption.

AMD5

MD5 is a cryptographic hash function used for verifying data integrity, not for encrypting data or entire partitions.

BLUKSCorrect

LUKS (Linux Unified Key Setup) is the standard open-source specification for disk encryption on Linux. It provides a platform-independent standard for on-disk format and management of encrypted volumes, making it suitable for encrypting entire partitions or disks on a Linux database host.

CBitLocker

BitLocker is a proprietary full-disk encryption feature developed by Microsoft, primarily for Windows operating systems, and is not an open-source technology for Linux.

Dext4

ext4 is a journaling file system for Linux, which manages how data is stored and retrieved on a disk; it does not inherently provide encryption capabilities for the data stored on the partition.
