The document describes the tasks and solution for a lab on VLANs and trunking. The tasks are to: 1) Configure IP addresses as shown in the topology, 2) Create DHCP servers for VLANs 10 and 20, 3) Configure SW1 as the VTP server and the others as clients with the domain "netwaxlab.com", 4) Ensure PCs get IP addresses via DHCP, and 5) Allow communication between PCs 9 and 10 which have different IPs on the same VLAN. The solution describes the configurations needed on the switches to accomplish these tasks.
