Labs
Hands-on labs designed to mirror real IT and sysadmin work — not certification trivia or toy examples.
20 Cisco Switch Commands Every IT Tech Should Know
Get comfortable on Cisco switches by learning the commands that help IT techs inspect ports, VLANs, trunks, MAC tables, neighbors, logs, and safe basic configuration. Built around real troubleshooting flows like finding an offline printer, verifying a wrong VLAN, and checking whether the issue is local or upstream.
Active Directory Basics
Build a real Active Directory environment from scratch in Azure. You'll create a domain controller, join a client, and work with users, groups, OUs, and authentication. This lab focuses on how AD actually behaves in production — not just what buttons to click.
DHCP Configuration
Deploy and manage DHCP servers in Windows Server. Configure scopes, reservations, failover, and troubleshoot common DHCP issues in enterprise environments. Learn DHCP configuration and troubleshooting that applies directly to production network administration.
Linux Basics — Part 1
Connect to a real Linux server and learn the commands you'll actually use on the job — navigating the file system, managing files, reading logs, searching with grep and pipes, and fixing permissions. You'll work through a real scenario like you just got SSH access to a server at work.
Azure VNet Peering
Connect two Azure virtual networks with peering and prove private connectivity across them. Follow detailed Azure Portal menus to build two non-overlapping VNets, private test VMs, bidirectional peering, break/fix exercises, and safe resource-group cleanup.
