Your network has two Distribution layer switches, Switch and Switch, connected through trunk ports on each of their respective Gi 0/1 interfaces. In addition, you recently connected an Access layer switch to the network, SwitchC. SwitchC has several workstations and a server belonging to VLAN 20. Because the resources on VLAN 20 are exclusive to the local workstations, you need to restrict VLAN 20's traffic from passing though the network on the trunk ports of SwitchC. In this lab, your task is to complete the following: Remove only VLAN 20 from the allowed VLANs on SwitchEs GigabitEthernet 0/1 and GigabitEthernet 0/2 interfaces. Save your changes to the startup-config file.
