Red Hat Certified System Administration Certification (RHCSA)
The RHCSA audience is not limited to professional Red Hat Enterprise Linux System administrators who are in search of validation for their skills. In addition to this, students who have attended classes for Red Hat System Administration 1 (RH 124) and classes for Red Hat System Administration 2 (RH134), and are trying to achieve RHCSA certification can also be the audience. Professional Linux system administrators that require the certification either by their respective organization or based on an authorization (DOD 8570 directive) can also earn the certification. Moreover IT professions who are aiming to achieve Red Hat Certified Engineer (RHCE) certification, and RHCEs who are non-current or will become one in the future and want to re-certify as RHCEs are all potential audiences.
Red Hat Certified System Administrator certification is basically an entry-level certification that was introduced in 2002 as Red Hat Certified Technician (RHCT). It was not until 2010, that it was renamed to RHCSA. Moreover, by July 2009, there were a total of 30,000 RHCTs.
Red Hat offers various levels of certification programs and Red Hat Certified System Administrator Certification is one of them. Among others are Red Hat Certified Engineer (RHCE), Red Hat Certified Architect (RHCA), Red Hat Certified Virtualization Administrator (RHCVA), and JBoss Certified Application Administrator (JBCAA).
Any IT professional who has earned (RHCSA®) can perform the required system administration skills needed in Red Hat Enterprise Linux environments. In order to earn this credential, one has to pass the Red Hat Certified System Administrator (RHCSA) Exam (EX200), a 2.5-hour hands-on lab exam. The minimum requirement is to have a score of 70% or in other words, the candidate must have at least 210 out of 300. In particular, there is no requirement for the exam but Red Hat suggests taking courses in Red Hat System Administration (RH124 or RH134) if one has no prior experience.
There are two paths to RHCSA, namely standard path, and boot camp. In the standard path, the first step is to take a class of Red Hat System Administration 1 (RH 124), followed by a class of Red Hat System Administration 2 (RH134). The exam can be taken on the 5th day of the class with the RH135 class. The third and the final step is to pass the EX200 Exam. As far as the Boot camp path is concerned, the first step is Rapid Track Course (RH199). The exam can be taken on the 5th day of class with the RH200 Class. The next and the final step is to pass the EX200 exam.
Once an individual passes the exam, he is able to perform various tasks. They include,
- Comprehend and use important tools for handling files, directories, command-line environments, and documentation
- Manage running systems, including booting into various run levels, recognizing processes, starting and stopping of virtual machines, and at the same time controlling services
- Build up storage with the help of partitions and logical volumes
- Create and arrange file systems along with file system attributes, such as permissions, encryption, access control lists and network file systems
- Organize, build up and maintain systems that include software installation, update, and other interior services
- Administer users and groups, including making use of a centralized directory to ensure authentication
- Handle security, including basic firewall and SELinux configuration
