Red Hat Certified Engineer (RHCE)

Red Hat Certified Engineer (RHCE)

A Red Hat Certified Engineer (RHCE) is a Red Hat Certified System Administrator (RHCSA) who possesses the additional skills, knowledge, and abilities required of a senior system administrator responsible for Red Hat Enterprise Linux systems.

The following audiences may be interested in earning RHCE:

  • RHCSAs who wish to earn a more senior-level credential.
  • Experienced senior system administrators who have not yet certified.
  • Course participants in Red Hat Training who have completed System Administration I, II, and II, or who have completed the RHCE Rapid Track Course.
  • Experienced system administrators who require certification for their job or by mandate (e.g., US Department of Defense Directive 8570).

Prerequisites for exam EX300

  • RHCE Rapid Track Course, System Administration I, II, or III or equivalent experience
  • Real-world system administration experience

The RHCE exam is a performance-based evaluation of Red Hat Enterprise Linux system administration skills and knowledge. Candidates perform a number of routine system administration tasks and are evaluated on whether they have met specific objective criteria. Performance-based testing means that candidates must perform tasks similar to what they must perform on the job.

The RHCE exam is a hands-on, practical exam that lasts 3.5 hours. Internet access is not provided during the exam. Outside materials are not permitted. Documentation that ships with Red Hat Enterprise Linux is available during the exam. Red Hat reserves the right to make changes to the format, including timing and the policies above. Such changes will be made public in advance through revisions to this document.
