As you may aware, all redhat exams are hands on exams. It is all about performing exam tasks. There are no multiple-choice questions and answers, matching terms, or purely hypothetical scenarios; you get a machine, and you either make it work according to the exam’s objectives, or fail. The idea is to simulate real-world scenarios.

As an EX294 exam candidate or EX407 exam candidate, you should be able to handle all responsibilities expected of a redhat Certified System Administrator, including these tasks:
