The RH302 exam encompasses multiple domains that professionals must master to achieve certification. Candidates are evaluated on their understanding of automation controller architecture, workflow design, and execution management. The examination tests practical skills rather than theoretical knowledge, requiring candidates to perform real-world tasks in a hands-on environment. This approach ensures that certified professionals can immediately apply their skills in production environments. The exam objectives align closely with actual job requirements that automation engineers encounter in enterprise settings. Understanding these core objectives helps candidates focus their preparation efforts on the most critical areas.
The architecture of Red Hat Ansible Automation Platform forms a foundational component of the RH302 exam content. Candidates must understand how the automation controller functions as the central hub for managing automation workflows across the enterprise. The platform consists of multiple integrated components including the automation controller, automation hub, and execution environments. Each component plays a specific role in the overall automation ecosystem. The automation controller provides a web-based interface and REST API for managing automation resources, while the automation hub serves as the repository for certified content collections. Execution environments ensure consistency across different deployment scenarios by packaging dependencies and runtime requirements together.
The automation controller represents the heart of the Ansible Automation Platform and receives substantial attention in the RH302 exam. This component provides centralized management capabilities for automation workflows, inventories, and credentials. The controller implements role-based access control to ensure appropriate security boundaries within organizations. It maintains detailed logs of all automation activities, providing audit trails and troubleshooting information. The scheduling functionality allows organizations to automate routine tasks without manual intervention.
