Explanation:
In this scenario, a Cisco Catalyst switch has been added to support the use of multiple virtual local area networks (VLANs) as part of an enterprise network. The network technician finds it necessary to clear all virtual local area network (VLAN) information from the switch in order to incorporate a new network design. To accomplish this task successfully, the technician should delete the startup configuration and the "vlan.dat" file residing in the flash memory of the newly added switch and lastly, he should reboot the switch. The VLAN informations are stored in a file with the name "vlan.dat" residing in the flash memory of the switch.
