Basic to intermediate Linux system administration
What you'll learn:- Students will be in a good position to pursue a career in Linux and also will be able to take the certification exam.
With a combination of lectures, hands-on exercises, quizzes and demos the students will get a very good grip of the Linux operating system and will be confident enough to take the test by the end of the course. The LFCS certification exam is performance based and hence needs a lot of practice, not memorization or brain dumps. You will be required to perform tasks on a live system and your score will be based on the correctness of the tasks performed. It is a 2 hour test and requires a 74% passing score.
LFCS is very high in-demand certification that is OS agnostic. Unlike some other certifications out there, you won't be required to stick to only one operating system. You will be given a choice to either pick up CentOS or Ubuntu as the operating system of your choice. Both of these operating systems are available for free and I will show you how to download and install them in a virtual environment in the first section of the course.
