Production web servers should use certificates issued by trusted Certificate Authorities (CAs).

B is correct: This describes the proper process—generate a private key, create a CSR (Certificate Signing Request), send it to a CA, and use the returned signed certificate for HTTPS.

Incorrect Options:

A: SSH keys are for SSH, not HTTPS/TLS.

C: Self-signed certs are insecure in production.

D: Irrelevant to HTTPS; /dev/random is used for entropy generation.

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:

The configuration file shown in the image is written in YAML format, so the syntax formatter should support YAML to correct any issues with the file. YAML stands for YAML Ain’t Markup Language, and it is a human-readable data serialization language that uses indentation and colons to define key-value pairs. YAML supports various data types, such as scalars, sequences, mappings, anchors, aliases, and tags. The configuration file follows the rules and syntax of YAML, while the other options do not. Markdown is a lightweight markup language that uses plain text formatting to create rich text documents. XML is a markup language that uses tags to enclose elements and attributes. JSON is a data interchange format that uses curly braces to enclose objects and square brackets to enclose arrays. References: CompTIA Linux+ (XK0-005) Certification Study Guide, Chapter 21: Automating Tasks with Ansible, page 591.
