RHCSA
RHCSA Training Institute in Surat
RHCSA is an entry-level certification that focuses on competencies at system administration, including installation and configuration of a Red Hat Enterprise Linux system and attach it to a live network running network services.
To achieve the RHCSA certification the student must pass EX200, a 3-hour hands-on lab exam. The minimum passing score for the exam is 210 out of 300 possible points (70%). There is no prerequisite for the exam, but Red Hat recommends preparing for the exam by taking courses in Red Hat System Administration (RH124 and RH134) if one does not have previous experience.
RHCSA was launched in 2002 as Red Hat Certified Technician (RHCT). As of July 2009 there were 30,000 RHCTs.In November 2010 it was renamed to RHCSA.
