CompTIA, which administers the Linux+ certification, is well-known for its slate of vendor-neutral foundation-level certifications. Linux+ is a basic, entry-level certification for Linux system administrators. Although initially created for technicians with six-months of experience installing, operating and maintaining Linux operating systems, the latest version of this certification suggests that 2 years or more experience is more appropriate. To achieve Linux+ certification, candidates must pass two exams consisting of 60 questions each. The exams cover system architecture; Linux installation and package management; GNU and Unix commands; devices; Linux filesystems; and the Filesystem Hierarchy Standard. This certification is not linked to any specific distribution of Linux.
In 2010, when an updated version of this certification was released that changed the number of required exams from one to two, the name was also changed to Linux+, Powered by LPI. LPI is the acronym for the Linux Professional Institute, which also offers a Linux certification program that is described below. CompTIA recommends Linux+ as a stepping stone to vendor-specific Linux certifications such as Oracle Certified Associate and Novell Linux certifications. It is also a good certification to use as a learning map if you are new to Linux and need to identify the skills that you need to grasp to be an effective Linux system administrator.
LPI: Linux Professional Institute Certified (LPIC) (launched January, 2000)
LPI is a non-profit organization that advocates and assists in the professional use of Linux, open source, and free software. The vendor-neutral LPIC program is three tiered, with each tier requiring passage of two exams. Level 1 (LPIC1) is for junior level administrators. Individuals must achieve level 1 (LPIC1) certification before attempting level 2 (LPIC2), the intermediate level designation. The top level is level 3 (LPIC3).
Novell: Certified Linux Administrator/Professional/Engineer (CLA/CLP/CLE) (Launched 2003)
Novell is best known for its Certified Novell Administrator and Certified Novell Engineer designations, but in 2003 it entered the Linux certification marketplace with a two-level certification program, which has since expanded to include additional options. This program focuses on the SUSE distribution of Linux.
The Novell Certified Linux Administrator (CLA) is for individuals who do the day-to-day administration of installed SUSE Linux Enterprise Server installations. The Certified Linux Professional (CLP) designation is the next step up for network administrators, and the Certified Linux Engineer (CLE) title is for Linux network architects and managers. Novell also offers a Certified Linux Desktop Administrator (CLDA) designation for individuals responsible for administering Linux in a desktop environment.
Red Hat: Red Hat Certified Technician/Engineer/Security Specialist/Architect (RHCSA/RHCE/RHCA)(Launched January, 1999)
Red Hat launched its certification program in January 1999 with the high-level Red Hat Certified Engineer (RHCE) designation. In November 2002, the entry-level level Red Hat Certified Technician (RHCT) title was added. Red Hat Certified Architect (RHCA) launched in 2005. With the release of the version RHEL6, the RHCT title was renamed RHCSA.
RHCE is for advanced system administrators who have quite a bit of experience to draw upon. To earn the RHCE certification you must pass a full day hands-on lab exam consisting of three elements: a written test, a server install and network services configuration lab, and a diagnostics and troubleshooting lab. The test is administered at a Red Hat facility. This is the most well-known advanced Linux certification currently available.
RHCA is the designation Red Hat calls its “capstone” certification, and it includes planning and designing and managing an open source infrastructure in large and complex environments.
RHCSA is intended as the “core” system administration certification offered by Red Hat. From the release of Red Hat Enterprise Linux (RHEL) 6, everyone who wishes to earn a system administration certification from Red Hat will begin by earning this credential. Red Hat Certified Engineer (RHCE) is intended as a senior system administration certification. In order to earn RHCE under Red Hat Enterprise Linux 6 and after, one must earn RHCSA and pass a separate RHCE exam on the same RHEL version.
Having a current RHCE certification remains an eligibility requirement for taking any Red Hat Certificate of Expertise Exam, and thus it remains a requirement for upper-level credentials such as Red Hat Certified Architect, Red Hat Certified Security Specialist, and Red Hat Certified Datacenter Specialist.

Photo IDs such as Passport, Driving License, Voter’s ID, Aadhar Card and PAN Card are some of the ID proofs accepted. Original ID proofs are required to be presented. Photo copies are not acceptable.
Red Hat certification programs validate people’s technical skills and knowledge. Organizations hiring employees, contractors, and consultants can look to Red Hat certifications as an input into hiring, assignment, promotion, and other management decisions. Similarly, individuals who earn these certifications benefit by having official, impartial validation of their skills and knowledge.
Performance-based testing is testing by doing — that is, by having examinees perform real-world tasks similar to those they must perform in a job role. Performance-based testing is also called hands-on or practical testing. All Red Hat certification exams are performance-based tests and Red Hat is the industry leader in IT performance-based testing.
