You volunteer as the network steward for the Meridian Robotics Club. The club just racked a new switch for the Fabrication Lab on VLAN 40, subnet 10.40.12.0/24. The gateway 10.40.12.1 and the internal DNS resolver 10.40.12.10 are already wired up as static infrastructure. Your job: configure server dhcp-core-01 to lease addresses to the lab workstations automatically — then verify and activate the scope from the console.
