What are the linux certifications?

Linux certification refers to the qualification obtained by passing the exam after obtaining professional Linux training.

Currently the internationally recognized Linux certifications include Linux Professional Institute (LPI for short), SairLinux and GNU, Linux and RedHatCertifiedEngineer. (Recommended study: linux operation and maintenance)

Linux Professional Institute (LPI)

Judging from the degree of concern of the Linux community , the LPI certification program has the widest support. LPI has already launched the Linux Profession Institute Certified-Level 1 (referred to as LPIC-1) certification program in advance, and will launch Level 2 and Level 3 certifications as planned in the near future.

In order to obtain the LPIC-1 certificate, you must pass two 90-minute exams each—101 (LPI General Linux, Part 1) and 102 (LPI General Linux, Part 2). LPI's LPIC-1 test candidates are mainly system administrators with at least 1 year of Linux work experience.

Sair Linux and GNU

Like LPI, Sair provides three levels of certification programs;

Level 1——Sair Linux & GNU Certified Administrator (LCA)

Level 2 ---- Sair Linux & GNU Certified Engineer (LCE)

Level 3 ---- Master Sair Linux & GNU Certified Engineer (MLCE)

Level 1 is the fully developed Sair certification program, which is the same as LPI.

Linux

The Linux certification program sponsored by CompTIA is the latest entry into the Linux certification market. The plan was officially launched on September 21, 2001, and has attracted widespread attention among Linux practitioners and the industry. Almost all major certification publishers have written exam reference books for Linux certification, and many IT training centers are preparing Linux certification programs.

Like other certifications with " " numbers launched by CompTIA, the Linux qualification certificate only needs to pass one exam (VUE and Prometric exam centers hold such exams). Once you obtain the Linux qualification certificate , the certificate will be valid for life. The price of the Linux exam is US$190. The exam uses multiple-choice questions and lasts 120 minutes. Many of the contents covered are exactly the same as the Sair and LPI certifications, but the difficulty is slightly lower.

LPI and Sair certification programs are aimed at Linux network and system administrators with considerable experience, while Linux certification is mainly for individuals who have only about half a year of Linux experience and want to obtain basic Linux technical qualifications.

Red Hat Certified Engineer

Linux represents the low-level Linux certification program, while the high-level Linux certification has long been almost exclusively the Red Hat Certified Engineer (RHCE) certification program the world. RHCE is the most challenging certification exam in the field, so it is also the most valuable Linux certification. But it is also the most expensive. The full course costs US$2,498. You can also take the certification test separately for US$749.
