The transition from RHCE 9 (based on RHEL 9) to RHCE 10 (based on RHEL 10) for the EX294 exam is not merely an incremental update; it is a significant shift that reflects the maturation of Red Hat Ansible Automation Platform (AAP) as an enterprise standard. Candidates who approach the v10 exam with a v9 mindset risk overlooking critical nuances. While the primary objective remains automating system tasks using Ansible, the way those tasks are structured has changed.
The first major shift is the complete elimination of deprecated systems. RHEL 10 has removed older packages and legacy configuration methods that were still optional in RHEL 9. Consequently, Playbooks that relied on older Modules or implicit behaviors will fail in the new environment. RHCE 10 demands a standard-first approach, moving away from simple one-off scripts toward robust, scalable automation. Candidates must master Ansible Collections and ensure they are utilizing fully qualified collection names (FQCNs) instead of short, legacy module names, signalling a deeper integration with the modern AAP ecosystem.
Secondly, the complexity of mandatory tasks has increased. Simple installation loops are being replaced by tasks requiring advanced logic. Error Handling is now a high-stakes component of the scoring matrix. A successful Playbook in RHCE 10 isn't just one that runs; it's one that can gracefully handle failures using advanced constructs like block, rescue, and always, demonstrating idempotent behavior and predictable outcomes under all scenarios. Furthermore, security automation, particularly fine-grained SELinux management via Ansible, is no longer optional but a central requirement. The exam environment is designed to test your ability to enforce security policies globally across the entire infrastructure.
