Red Hat Certified Technician (RHCT) and Red Hat Certified Engineer (RHCE) are performance-based tests that measure actual competency on live systems. RHCT is the first step in establishing Linux credentials and is an ideal certification for those transitioning from non-UNIX/Linux environments. RHCE, called the "crown jewel of Linux certifications," proves an individual's ability to configure networking services and security on servers running a Red Hat OS. RHCE was recently named the hottest certification in all of IT by CertCities.com.
