LPIC 3 - Exam 301: Core
timofte andrei
Linux, originally created by Linus Torvalds, is an operating system that is freely distributed under the terms of the GNU Public License. The Linux Professional Institute (LPI) is a non-profit organization that provides vendor-independent professional certification for Linux system administrators and programmers. Linux Professional Institute has a fundamental interest in championing workforce development initiatives for Linux and Open Source professionals. It also work on wider industry initiatives to promote the creation of Linux jobs and the recognition of the value of IT certification. The Linux Professional Institute Certifications (LPIC) provides a qualification that can be used to indicate that someone is competent at a certain level. The exams cover a range of different Linux based topics. The exams are available in almost every country in the world, and are translated into a number of different languages. The exams are primarily multiple choice questions, with some written answers. These are either taken using a computer based system, or using a paper based exam. The organisation encourages active community participation in creating and updating exams. Anyone can use the exam Objectives Development wiki, or the Exam Development Mailing List to participate in the creation of new exams and the update of the existing ones. The exams are distribution-neutral, requiring a general knowledge of Linux rather than specifics about a certain distribution. This is shown in the way that the exams deal with the differing package management formats .deb and .rpm. In earlier versions of the test one of these was chosen by the candidate. In the current version the candidate is expected to know both formats. The examinations can be taken at any Pearson VUE testing center worldwide. LPIC-3 is designed for the enterprise-level Linux professional. The program has been developed with the advice of hundreds of Linux professionals and some of the world's leading technology companies. It also represents the highest level of professional, distribution-neutral Linux certification within the industry. Exam 301 is the sole exam for LPIC-3 designation. It tests skills in authentication, troubleshooting, network integration and capacity planning.
