1. Download JBoss EAP 7.x from the Red Hat Customer Portal, install it to /opt/jboss-eap, set proper permissions for the jboss user, and verify the installation by starting the standalone server and accessing the CLI.

2. Create a systemd service for JBoss EAP standalone server so it starts automatically on boot.

3. Secure the JBoss management interface by creating a user with the ManagementRealm. Verify by logging into the web admin console.

4. Bind the JBoss server to all IP addresses and secure it using management interface access restrictions in standalone.xml.

5. Install a JBoss EAP domain mode setup on two hosts (host1 and host2), where host1 is the Domain Controller and host2 is a Host Controller.

6. Add a new server group in domain mode named web-servers with the full-ha profile and assign two servers to it.

7. Configure JBoss EAP to run under a dedicated service account jboss, ensure this user owns all files, and test that it starts and manages the server properly.

8. Secure the management interfaces using a custom user role with reduced privileges that only allows monitoring.

9. Access the JBoss CLI remotely from your admin workstation and connect to a running domain controller.

10. Configure the standalone.sh to run as a background daemon with log redirection to /var/log/jboss/standalone.log.

11. Create a CLI script to configure a new management user and deploy a .war file to a new server group api-servers.

12. Set up SSL for the management console using a self-signed certificate stored in a Java keystore.

13. Configure audit logging to track all management operations and save to /var/log/jboss/audit.log.

14. Deploy an application to a specific server (not server group) using CLI in domain mode.

15. Configure a backup Domain Controller in the domain and test failover between two hosts.

16. Add a custom system property (ENV=production) and access it from a deployed app.

17. Configure logging so that all error-level logs from a deployed app are written to /var/log/jboss/app-errors.log.

18. Perform a rolling deployment of an updated WAR file across two servers in the same server group.

19. Enable HTTP access logging and set it to rotate logs daily with a max history of 7 days.

20. Deploy a datasource using CLI, configure it to connect to a MySQL database, and test connection.

21. Configure a multi-server domain on a single host where two servers (server-one and server-two) belong to different server groups and profiles.

22. Set up a two-host domain (dc-host and hc-host). Configure dc-host as the Domain Controller and hc-host as the Host Controller. Configure authentication using secret-value and test connectivity.

23. Configure a clustered application in domain mode with mod_cluster and load balancing using Apache HTTPD and mod_cluster.

24. Configure HA singleton deployment so only one instance runs in a cluster at any time.

25. Create and execute a CLI batch script that adds a data source, enables it, and tests the connection in a domain server group.

26. Enable JMX monitoring over remote connections secured with SSL and restricted to admin users.

27. Implement centralized logging for multiple JBoss EAP nodes using rsyslog to a remote log server.

28. Set up graceful shutdown for all servers in a domain using CLI to avoid interrupting live requests.

29. Tune JVM heap settings for a specific server in the domain to allocate 4GB min and 6GB max.

30. Configure Elytron subsystem to replace legacy security realms and enforce strong password rules.
