Red Hat / Advanced / EX294
Ansible Advanced Administration — RHCE Path
Turn Linux administration into repeatable, tested Ansible automation with persistent results.
Red Hat’s current page names EX294 Advanced System Administrator in Ansible, although its URL retains the older RHCE wording. The Engineer credential has additional pathway requirements. Product versions can differ by booking: the public objectives target the newest offered version, so verify your selected RHEL/AAP environment before practicing. Notes are not permitted exam reference material.
THE REVISION PATH
Your topics, in order.
Read. Recall. Explain the alternative.
Inventory, Configuration and Execution Environments
Know the targets, settings and runtime before the first task.
Connectivity, Privilege and Safe Execution
Connection proves access; become proves authority; state proves success.
Plays, Variables, Facts and Loops
Describe the state once, parameterize the differences.
Handlers, Failure Paths and Idempotence
A change should trigger only the work it requires.
Roles, Collections and Documentation
A role organizes intent; a collection distributes content.
Automating Packages, Services, Storage and Networking
Configure the dependency chain, then verify the service.
Templates, Accounts, SELinux and Vault
Render the right file, enforce the right access, protect the secret.
Git, VS Code and Practical Exam Verification
Save the automation, prove the result, then prove repeatability.
Shell Tools and Scripts
Quote paths; check status; know where output goes.
Users, Permissions and SELinux
Identity, mode bits and labels must all agree.
Software, Services and Logs
Installed is not running; running is not enabled.
Storage, Filesystems and Persistent Mounts
Disk to PV to VG to LV to filesystem to mount.
Networking, SSH and Firewalls
Address, route, name, socket, policy.
Boot, Scheduled Work and Recovery
Make it work now, at boot and after failure.
How this guide is organised
Original Ansible revision chapters followed by six explicitly shared RHCSA foundation chapters. The current Red Hat objectives define scope; Ansible documentation supports technical explanations. Rehearse on disposable systems and verify the booked product versions.
