Thanks to Linuxacademy and Stosh Oldham for Red Hat Certified Specialist in Ansible Automation (EX407) Preparation Course. This has helped me enormously to pass this exam on the first attempt. The course seems very complete, easy to follow and at the same time entertaining. I encourage anyone who wants to be certified in Ansible to do it.
The most important thing is what has been learned.
The exam did not seem too difficult. This course covers everything necessary for its approval.
