An administrator wants to prevent user traffic from traversing the default virtual network on a Cisco switch to improve security. Which of the following is the best method to achieve this?
Change the identifier of the default virtual network to a different number
Assign all access interfaces to virtual networks other than the default
Remove the default virtual network from the switch configuration
To prevent user traffic from traversing the default VLAN (VLAN 1), the best practice is to assign all access ports to VLANs other than the default. The default VLAN cannot be deleted, renamed, or disabled, and changing its identifier is not possible. By moving all access ports to other VLANs, user traffic is kept off the default VLAN, enhancing network security.
