Redhat Certified System Administrator RHCSA exam

By
John Faith

Red Hat Certified System Administrator (RHCSA) was launched in November 2010. It replaces the old Red Hat Certified Technician (RHCT) qualification.

The RHCSA exam (EX200) is 100% performance-based, coming after a review of the knowledge and skills required daily by today’s system administrators.

Since 2010, the RHCSA has been made a prerequisite for those taking the Red Hat Certified Engineer (RHCE) qualification.

This exam and the exam objectives provided here are based on the Red
 Hat®Enterprise Linux® 7 version of the exam.

The performance-based RHCSA exam (EX200) tests your knowledge and skill in areas of system administration common across a wide range of environments and deployment scenarios. You must be an RHCSA to earn a Red Hat Certified Engineer (RHCE®) certification. The skills tested in this exam are the foundation for system administration across all Red Hat products.

An RHCSA certification is earned when an IT professional demonstrates the core system-administration skills required in Red Hat Enterprise Linux environments.

 

 To pass the redhat exam you must be able to accomplish many points :
