CompTIA Network+ Labs

Every lab is free and does real work on a real system — not a simulation inside a courseware player. Each one says up front what it needs, and ends with commands you run to check your own work.

Most labs want a disposable virtual machine or container, and many need root. Each lab states its own requirements before the first step.
