Red Hat JBoss Application Administration I (AD248) — Lesson 1: EAP Architecture, Installation, Standalone Servers, Domains, and Management

Learning Objectives

• Explain the structures, services, data, settings, roles, and dependencies governing EAP architecture and installation.
• Implement and validate standalone servers, managed domains, and CLI and console using reviewable evidence.
• Evaluate the condition where the observed result differs from the approved configuration because a prerequisite, permission, dependency, or sequence was missed and select a proportionate corrective response.

Detailed Topics

• EAP architecture applied to the course scenario, expected platform behavior, dependencies, controls, and evidence.
• installation applied to the course scenario, expected platform behavior, dependencies, controls, and evidence.
• standalone servers applied to the course scenario, expected platform behavior, dependencies, controls, and evidence.
• managed domains applied to the course scenario, expected platform behavior, dependencies, controls, and evidence.
• CLI and console applied to the course scenario, expected platform behavior, dependencies, controls, and evidence.

Instructor Demonstration

The instructor traces a middleware administration team preparing JBoss EAP services for secure, repeatable enterprise application delivery. The walkthrough connects navigation, commands, configuration logic, system messages, and evidence captured in the JBoss EAP administration baseline, deployment and resource records, monitoring checklist, and recovery runbook. It also tests the exception where the observed result differs from the approved configuration because a prerequisite, permission, dependency, or sequence was missed.

Hands-On Exercise

Complete a controlled Red Hat exercise covering EAP Architecture, Installation, Standalone Servers, Domains, and Management and preserve the verified result in the JBoss EAP administration baseline, deployment and resource records, monitoring checklist, and recovery runbook.

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 EAP architecture.
• Compare two defensible responses and explain technical, security, operational, and support trade-offs.
• Determine how the JBoss EAP administration baseline, deployment and resource records, monitoring checklist, and recovery runbook 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 “the observed result differs from the approved configuration because a prerequisite, permission, dependency, or sequence was missed” 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 JBoss EAP administration baseline, deployment and resource records, monitoring checklist, and recovery runbook 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 EAP Architecture, Installation, Standalone Servers, Domains, and Management, explain the resulting platform behavior, and defend the outcome through the JBoss EAP administration baseline, deployment and resource records, monitoring checklist, and recovery runbook.
