This is part of the full CompTIA Network+ course covering all five exam domains, taught in plain English with exam-style questions throughout.

Free CompTIA Network+ N10-009 course, part 2: 27 plain-English lessons from DHCP and DNS to routing, VLANs, wireless, cloud and monitoring.

Part 2 picks up where part 1 ended and covers network services, topologies, routing and switching, wireless, cloud and virtualisation, and the tools used to monitor and document a network. You will hear how DHCP and DNS work, how static and dynamic routing choose a path, how NAT, VLANs, trunks and Spanning Tree behave, and what SD-WAN, VXLAN and infrastructure as code add. It is built for career changers, help desk staff and anyone preparing for the Network+ exam, and every lesson ends with a quick self-check, so pause and answer before you hear the answer. Part 3 finishes the course with high availability, security and troubleshooting.
