A systems administrator is tasked with creating an Ansible playbook to automate the installation of...

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.
