FreeBSD, NetBSD and OpenBSD share an ancestry, but an exam question can turn on the command or configuration file they do not share. Package tools, rc service control, persistent network configuration and kernel handling are exactly where Linux muscle memory becomes unhelpful. I condensed those differences into a printable one-page BSD Specialist Cheat Sheet.
The guide covers the five weighted objective areas, common administration workflows, cross-BSD command differences and the Unix tools expected by the exam. It follows version 1.0 of the official LPI BSD Specialist objectives for exam 702-100 and is intended for a final pass after hands-on preparation, not as a replacement for the objectives or the BSD manuals, which can change.
