Getting ready for LPIC-1 exam 102-500? These four practice tests let you check what you know before exam day - and, more importantly, show you why.

Every question has four options, and every option is explained: why the right answer is right, and why each wrong one is wrong. So a missed question turns into a short lesson rather than a mystery.

What's inside

• Test 1 - Shells, Desktops and Administrative Tasks (topics 105-107, 50 questions): environment files, Bash functions and scripts, X11 and remote displays, accessibility, users and groups, cron, at and systemd timers, locales and time zones.
• Test 2 - Essential System Services and Networking (topics 108-109, 50 questions): time and NTP, rsyslog and the systemd journal, logrotate, mail aliases and forwarding, CUPS printing, subnets and ports, NetworkManager, iproute2 troubleshooting and client-side DNS.
• Test 3 - Security, plus a Second Pass (topic 110 and harder questions from 105-109, 50 questions): SUID audits, sudo, limits, TCP wrappers, OpenSSH keys and tunnels, GnuPG encryption and signatures.
• Test 4 - Full Mock Exam (50 questions, timed): mixed questions weighted like the published exam objectives.

Every question names the public LPI exam objective it practises (for example, "107.2 Automate system administration tasks by scheduling jobs"), so you can see at a glance which objectives need more work.

The questions are written from the public LPI objectives for exam 102-500 (objectives version 5.0). They are original practice questions, not copies of exam questions. The real exam (60 questions, 90 minutes) also has fill-in-the-blank questions, which these multiple-choice tests can't reproduce; where it helps, the explanations name the exact command or file you'd type.

Before you start: take the topic tests first, read the explanations for anything you missed, and save Test 4 for when you feel ready. Aim for a steady 70% or more before you book the exam.
