Unlike the "trifecta" certifications, L+ is not an entry-level accreditation. Linux+ is a certification in which candidates are led to present competence in configuring, administering and troubleshooting Linux clients and servers. To that end, it is theoretically possible to "memorize" facts and pass the exam. That's hard. There are a lot of domains and objectives to memorize. The certification is best achieved by candidates with regular, hands-on experience running Linux boxes. The repetition leads to understanding and the understanding leads to understanding related topics. This continues until the entire system is understood and expertise is developed in certain areas. This makes the exam relatively easy. Hands on practice is the best way to ingrain the information. Fire up a VM, install distro(s) on a spare machine, use a Raspberry Pi running Raspberry Pi OS or Ubuntu or something else. I recommend running 3 distros and practicing every concept on all of them: VM running Ubuntu VM or Ras Pi running an enterprise distro such as Rocky Linux Ras Pi running Raspberry Pi OS. Best in your studies. Answer from drushtx on reddit.com
