EX200: Red Hat® Certified System Administrator Exam

The Red Hat Certified System Administrator exam is a performance-based evaluation of Red Hat Enterprise Linux system administration skills and knowledge. You will perform a number of routine system administration tasks and be evaluated on whether you have met specific objective criteria. Performance-based testing means that you must perform tasks similar to what you would perform on the job.

Note: Red Hat does not guarantee that anyone who takes one or all of the courses in the Red Hat certification program will pass a Red Hat exam. On-the-job experience, in combination with high-quality training, is the best way to build skills and prepare for a Red Hat exam. The exam itself is a hands-on learning experience, and many of those who do not pass on the first try come away with knowledge of what they need to work on to pass the exam on a re-take.
