The RHCSA & RHCE animated track.
Every topic on the EX200 and EX294 exams, organized by Red Hat's official course breakdown (RH124, RH134, RH294). Lessons with animations link in as they ship — the rest are the map you'll fill in as you go.
RHCSA EX200 and RHCE EX294 exam preparation. Animated lessons covering the full RH124 (System Administration I), RH134 (System Administration II), and RH294 (Automation with Ansible) syllabus.Red Hat System Administration I
Foundations. Day-one skills any RHEL admin needs: shell, files, users, permissions, processes, networking, and software management.
Navigate the Bash shell, run commands, use redirection and pipes.
Locate files; understand /etc, /var, /usr, /home, /tmp layout.
Open, edit, and save text files in Vim.
Expand wildcards; quote properly for special characters.
Create, modify, lock, and delete local user/group accounts.
Read, change, and reason about file/directory permissions.
Explain and set the special permission bits.
Grant fine-grained access beyond standard ugo permissions.
Inspect, foreground, background, and signal processes.
List, start, stop, enable, and disable systemd services.
Understand units, Requires/Wants/After/Before, target nesting, isolate.
Query and filter journal logs by service, time, priority.
Configure interfaces with NetworkManager (nmcli).
Install, update, and remove packages; manage repos.
Connect, configure, and harden SSH access.
Red Hat System Administration II
Depth. Storage, boot, SELinux, firewalld, scheduling, containers, and the operational topics that show up heavily on the RHCSA exam.
Create and manage MBR/GPT partitions with parted.
Create, mount, and unmount XFS/ext4; configure /etc/fstab.
Build, extend, and snapshot LVM volumes.
Use Stratis for thinly provisioned, layered storage.
Add and configure swap partitions and files.
Read/set file contexts; troubleshoot denials with audit2why.
Toggle policy switches with setsebool.
Configure firewalld zones, services, and rules.
Generate, distribute, and harden SSH keys.
BIOS/UEFI → GRUB → kernel → initramfs → systemd target.
Edit GRUB params; recover root passwords.
Pass kernel args; switch tuned profiles.
Schedule one-shot and recurring jobs.
Run, manage, and persist Podman containers as systemd units.
Red Hat System Administration III (Ansible)
Automation. RHCE focuses on Ansible: playbooks, roles, variables, conditionals, loops, error handling, and managing scale across fleets.
Install Ansible, write inventories, run ad-hoc commands.
Write, run, and debug playbooks. Idempotency.
Use core modules to manage Linux resources.
Define, override, and gather variables/facts.
Iterate over lists; use when/changed_when/failed_when.
Render config files dynamically with Jinja2.
Trigger actions only when changes occur.
Structure reusable playbooks as roles; use galaxy/collections.
Encrypt sensitive data with ansible-vault.
block/rescue/always; ignore_errors and failed_when.
