A company is migrating from a Windows Server to Linux-based servers.

The correct snippet is Option A, which shows an Ansible YAML playbook designed to deploy and maintain security software on Linux servers. Ansible is a configuration management tool widely used in enterprise environments, and the ansible.builtin.apt module specifically manages package installation on Debian/Ubuntu-based Linux distributions. This ensures consistent security software deployment across multiple servers.

Option B is XML-based and does not represent a valid configuration management script. Option C incorrectly uses JSON format and references Microsoft’s store (com.microsoft.store.latest), which is irrelevant for Linux. Option D also uses JSON syntax with “AppX,” which applies to Windows applications, not Linux.

CAS-005 emphasizes infrastructure as code (IaC) and automation as best practices for secure system configuration. YAML-based playbooks in Ansible provide repeatability, auditability, and scalability, making Option A the most secure and appropriate solution.
