Linux+
Linux+ is a CompTIA certification of knowledge of Linux operating systems, from their installation and use to the basics of applicable free software and open source licenses.
The Linux+ exam is intended for Information technology professionals who have at six to twelve months of practical experience using Linux. The exam is broken down into several areas of Linux expertise: installation, management, configuration, security, documentation, and hardware.
The format of the test is multiple-choice, with a question followed by four possible answers, at least of one (but possibly more) of which must be correct.
The Linux+ exam has undergone some criticism since its inception, due to the excessive amount of hardware-related questions that were on the exam initially, many of which were covered on the A+ exam. The newest version of the exam, available as of February 2005, does away with this problem.
The Linux+ has not proven to be very popular among IT professionals, primarily because of the much greater level of difficulty of the RHCE exam and the higher skill level required to pass it, as well as the popularity of the Red_Hat Linux Distribution, whereas the Linux+ exam is designed to remain vendor-neutral. Although aimed at technicians rather than system administrators, the LPI exams, which go into much greater depth, also provide a lot of competition for this exam.
