Candidates who successfully gain the Linux+ credential will have demonstrated their ability to manage Linux systems from the command line, have good knowledge of user admin, file permissions and software configuration as well as good foundation skills in the management of Linux-based clients, server systems and, increasingly, security issues. Linux security concepts tested include implementing security options on client systems, configuring security-related files and other general security practices. Because the Linux+ certification is vendor-neutral, the concepts tested apply across various Linux distributions therefore candidates should be comfortable working on various Linux flavors.
To become Linux+ certified, candidates need only pass one exam (XK0-002) consisting of 98 questions and a time allocation of up to 90 minutes. The questions are presented in multiple-choice, linear format, meaning the Linux+ test is non-adaptive and there are no simulation-type questions. Candidates may navigate backward and forward through the exam and mark questions in order to answer them at a later stage throughout the test. The exam is available in both English and Japanese and can be taken at any Prometric or Pearson VUE testing station. You can find your nearest testing station here .
The passing score for the Linux+ exam is a minimum of 675 points from a scale of 100-900. Candidates who pass the exam will be awarded the Linux+ credential. Candidates who fail on their first attempt have the opportunity to retake the exam whenever they wish (with payment of the fee again), however subsequent failures mean that the candidate must wait at least 30 calendar days between attempts.
While topics such as planning, installation and configuring are covered, approx. 80% of the exam is weighted toward areas such as general troubleshooting, maintenance, administration and security. As with all Linux certifications, real world experience with troubleshooting and admin aspects of Linux can only increase your chances of passing this exam. A full list of the exam objectives can be downloaded from the CompTIA website and you should always double-check that you have the latest objectives prior to writing the exam.
