Red Hat Certified System Administrator

Course Details

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.
