Question:
An administrator issues the show vlan brief command on a Cisco switch and the output shows that all ports are currently assigned to the default VLAN. What conclusion can be drawn?

• Layer 2 control traffic is not associated with any VLAN.
• The switch cannot be remotely managed using Telnet or SSH until a management VLAN has been created.
• All user data traffic will be separated and secured from other users.
• There is a security risk because the management VLAN and the native VLAN are the same.
