RED HAT CERTIFIED TECHNICIAN

RHCT EXAM

The RHCT certification exam consists of two parts conducted in a half-day session. The exam is performance-based, meaning that candidates must perform tasks on a live system, rather than answering multiple choice questions. The two parts of the RHCT exam are:

• Section I: Troubleshooting and System Maintenance (1 hour)
• Section II: Installation and Configuration (2 hours)

In order to pass the Red Hat Certified Technician exam, you must meet all of the following requirements:

• Successful completion of all troubleshooting problems in Section I (all troubleshooting problems are compulsory);
• A score of 70 percent or higher on Section II, Installation and Configuration.

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