At the beginning of this month, I took the EX294 exam, which allowed me to obtain the Red Hat Certified Engineer (RHCE) certification. It was the first time I attempted the RHCE exam, but I prepared myself in the past for the EX300 exam, the exam that allowed you to obtain the RHCE certification in the RHEL7 time, but never got around to do the exam.
Compared to what I had to study for the EX300, I found the EX294 program way more sensible. An aspect I’ve never liked about the EX300 was that you needed to learn many implementation details, such as the in-scope applications’ configuration format. EX294 changed this aspect since it is based on Ansible, and Ansible abstracts the majority of implementation details of the various applications.
The EX294 is about the concepts more than the details. Consider that you have the Ansible documentation available during the exam! Though it does help to know the details since it speeds you up a lot, and there are some corner cases that you either know or do not know.
Overall, the EX294 is a far more appropriate exam than the old EX300 to certify if a person is at an Engineer level.
