The following commands can help you confirm that the new RAID adapter has been recognized by the Linux system:

dmesg: This command displays the kernel messages, which can show the information about the newly detected hardware device. You can use dmesg | grep -i raid to filter the output for RAID-related messages.

lshw -class disk: This command lists the disk devices on the system, including the RAID controller and its model name. You can use lshw -class disk | grep -i raid to filter the output for RAID-related information1.

The other commands are not relevant for this purpose. For example:

rmmod: This command removes a module from the Linux kernel, which is not useful for detecting a new device.

ls -l /etc: This command lists the files and directories in the /etc directory, which is not related to hardware devices.

pvdisplay: This command displays the attributes of physical volumes, which are part of the logical volume management (LVM) system, not the RAID system.

rmdir /dev: This command removes an empty directory, which is not helpful for detecting a new device. Moreover, /dev is a special directory that contains device files, and should not be removed.

The language that the playbook should be written in is YAML. YAML stands for YAML Ain’t Markup Language, which is a human-readable data serialization language. YAML is commonly used for configuration files and data exchange. YAML uses indentation, colons, dashes, and brackets to represent the structure and values of the data. YAML also supports comments, variables, expressions, and functions. Ansible is an open-source tool for automating tasks and managing configuration on Linux systems. Ansible uses YAML to write playbooks, which are files that define the desired state and actions for the systems. Playbooks can be used to automate the installation of patches on several Linux systems by specifying the hosts, tasks, modules, and parameters. The language that the playbook should be written in is YAML. This is the correct answer to the question. The other options are incorrect because they are not the languages that Ansible uses for playbooks (SQL, HTML, or JSON). References: CompTIA Linux+ (XK0-005) Certification Study Guide, Chapter 18: Securing Linux Systems, page 549.

Using AD Query, the security gateway connects to the Active Directory Domain Controllers using Lightweight Directory Access Protocol (LDAP). LDAP is a protocol that provides access to directory services over a network. AD Query uses LDAP queries to retrieve information about users and groups from Active Directory Domain Controllers without installing any software on them. AD Query does not use Windows Management Instrumentation (WMI), Hypertext Transfer Protocol Secure (HTTPS), or Remote Desktop Protocol (RDP) to connect to Active Directory Domain Controllers. References: Check Point Certified Security Administrator (CCSA) R80.x Study Guide, Chapter 5: User Management and Authentication, page 69.
