RHCT and RHCE Exam Preparation Guide   Overview This guide provides information candidates may use in preparing to take the RHCT or RHCE exam. The Red Hat Certified wangle (RHCE) and Red Hat Certified Technician (RHCT) exams are performance-based evaluations of Red Hat Enterprise Linux and Red Hat 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. Exam results Official scores for the RHCE and RHCT exams come exclusively from Red Hat Certification Central. Scores on the exam are usually reported within three (3) US business days.   Components of the RHCE and RHCT Exams The RHCT exam is a subset of the RHCE exam, and is organized as follows: Troubleshooting and System Maintenance — 1 hour Installation and Configuration — 2 hours In order to earn RHCT, one must successfully complete all the requirements in Troubleshooting and System Maintenance, and must achieve a score of 70 or higher on Installation and Configuration. For RHCE exams given on Red Hat Enterprise Linux 3 and higher, the exam is organized as follows:  ·  Troubleshooting and System Maintenance — 2.5 hours  ·  Installation and Configuration — 3.0 hours In order to earn RHCE, one must successfully complete all the RHCT-level Troubleshooting and System Maintenance requirements, and successfully complete enough additional RHCE items to earn a score of 80 or higher overall on the section.
