CompTIA Linux+ Certification Training

CompTIA Linux+ is the most popular Linux certification in the world. It’s a must-have for anyone who wants to work in this area of IT. It’s now in its 20th year and has recently been updated, marking a shift from the LIPC1 syllabus (which it now shares around 60% content with).

All US government jobs and contracts require IT staff to possess a CompTIA certification for the technology they support. Linux is also tested in Cisco exams.

This course has been completely revised and updated for the brand-new Linux+ exam:

CompTIA Linux+ Certification

Linux runs the Internet and is used by over 90% of companies. There is currently a huge demand for Linux engineers to configure and maintain the IT infrastructure for companies large and small worldwide.

Linux is used on many devices every day, from smartphones to cars, supercomputers, home appliances, desktops, and enterprise servers. The Linux operating system is ubiquitous, in fact.

Linux has been growing since the late 1990s and has a user base that spans the globe. You can find Linux running the software on your phones and IoT devices, including your thermostats, cars, refrigerators, Roku devices, and televisions. It also runs most of the Internet, the world’s top 500 supercomputers, and the world’s stock exchanges.

We take you by the hand and guide you through the entire Linux+ syllabus from start to finish. Included are more than $400 worth of CompTIA Linux+ practice tests, advanced multi-technology labs, real-world and exam tricks, and tips to guarantee your success come exam day.

Your course is taught by a Linux industry expert who designs, configures, and supports Linux for international companies. He shares his decades of experience with you as you learn the insider tips and secrets you can use as a Linux engineer.

Linux is tested in most IT exams from Cisco, CompTIA, Ethical Hacking, WiFi Engineer, Software Engineer, and more. You must learn it to work in the modern IT industry. If you need to know the theory, please check out our sister website, howtonetwork.com, for CompTIA Linux+ training.

Please allow around two months of study to prepare for the Linux+ exam. Since the Linux LPIC-1 exam is almost identical, you should also take it around the same time.
