Red Hat EX457 exam

 August 31, 2025

Last week, I renewed my Red Hat Certified Specialist in Ansible Network Automation (EX457) certification. As I’m already a Red Hat Certified Architect and have passed this same exam a couple of years ago, I wasn’t too worried about it. Still, it is always interesting to see how exams evolve.

Since I did not remember the kind of content that was there last time, I read the objectives page and assumed it would have been more on the networking side. But, in reality, the exam leaned much more toward Ansible playbooks, modules, and automation patterns than network-specific plumbing.
