Unit 3 — Connecting systems in a network¶
This unit follows the official MikroTik Certified Network Associate (MTCNA) syllabus: nine modules, each with its theory pages and hands-on labs on RouterOS v7. At the end of the unit you can sit the MTCNA exam.
How the labs work
In class every router is cabled to the class AP; WiFi is only the backup if the cable is not available. At home or on your own, each lab also runs as a virtual network in containerlab: download the zip from the guide, deploy topology.clab.yml, follow the steps, and run ./check.sh to see if you solved it. final.clab.yml shows the solution.
The MTCNA slides cover the whole course.
