Red Hat Certified Architect (RHCA) — Lesson 2: Automation, Ansible Automation Platform, Security, Reliability, and Operations

Learning Objectives

• Explain the structures, services, data, settings, roles, and dependencies governing automation architecture and Ansible Automation Platform.
• Implement and validate security, reliability, and operational governance using reviewable evidence.
• Evaluate the condition where a change succeeds in one environment but fails elsewhere because inventory, policy, version, or runtime assumptions differ and select a proportionate corrective response.

Detailed Topics

• automation architecture applied to the course scenario, expected platform behavior, dependencies, controls, and evidence.
• Ansible Automation Platform applied to the course scenario, expected platform behavior, dependencies, controls, and evidence.
• security applied to the course scenario, expected platform behavior, dependencies, controls, and evidence.
• reliability applied to the course scenario, expected platform behavior, dependencies, controls, and evidence.
• operational governance applied to the course scenario, expected platform behavior, dependencies, controls, and evidence.

Instructor Demonstration

The instructor traces a senior engineer assembling a coherent Red Hat architecture pathway and demonstrating cross-domain solution leadership. The walkthrough connects navigation, commands, configuration logic, system messages, and evidence captured in the RHCA capability portfolio, specialization roadmap, architecture case study, and continuing development plan. It also tests the exception where a change succeeds in one environment but fails elsewhere because inventory, policy, version, or runtime assumptions differ.

Hands-On Exercise

Complete a controlled Red Hat exercise covering Automation, Ansible Automation Platform, Security, Reliability, and Operations and preserve the verified result in the RHCA capability portfolio, specialization roadmap, architecture case study, and continuing development plan.

1. Confirm scope, prerequisites, versions, identities, dependencies, and acceptance criteria.
2. Execute the workflow while recording commands, settings, outputs, events, and system messages.
3. Test normal behavior, one boundary condition, and the stated exception.
4. Document corrections, evidence, ownership, retest criteria, rollback, and handover actions.

Scenario Analysis

• Identify which object, service, policy, setting, or sequence most strongly influences automation architecture.
• Compare two defensible responses and explain technical, security, operational, and support trade-offs.
• Determine how the RHCA capability portfolio, specialization roadmap, architecture case study, and continuing development plan should be approved, retained, retested, and updated.

Troubleshooting Guidance

Start where expected behavior first differs from the observed result. Check prerequisites, identity, configuration order, version compatibility, connectivity, status, resource limits, and evidence separately. Treat “a change succeeds in one environment but fails elsewhere because inventory, policy, version, or runtime assumptions differ” as a hypothesis until commands, logs, settings, and retest outcomes confirm the cause.

Validation Checklist

• Required platform components, identities, permissions, settings, and dependencies are present.
• The RHCA capability portfolio, specialization roadmap, architecture case study, and continuing development plan connects each conclusion to objective, reviewable evidence.
• Normal processing, a boundary condition, dependency behavior, and the stated exception were tested.
• Corrections, ownership, retest criteria, rollback, documentation, and operational handover are complete.

Lesson Outcome

Learners can apply Automation, Ansible Automation Platform, Security, Reliability, and Operations, explain the resulting platform behavior, and defend the outcome through the RHCA capability portfolio, specialization roadmap, architecture case study, and continuing development plan.
