The RHCSA exam objectives provides authoritative guidance on the knowledge and skills candidates will need to demonstrate in the RHCSA exam. It also provides more specific information on the exam format and coverage. All candidates are urged to use this information to evaluate their readiness for the exam.

Candidates will be emailed exam results within three business days following the exam.
