Which command do you use to determine what VLAN a port is a member of?

• A. Show Interfaces
• B. VLAN Status
• C. Show VLAN
• D. Display VLAN

Answer: (C)

To find which VLAN a port belongs to, you need to look at the switch’s VLAN membership information. The command that directly reveals this mapping lists each VLAN and the ports assigned to it, so you can see exactly which VLAN a given port is in. On Cisco devices this is typically shown by the command that displays VLANs and their member ports, often seen as show vlan or show vlan brief for a concise view. Other options don’t give a straightforward view of the port-to-VLAN mapping: show interfaces shows per-interface details but not the overall VLAN-to-port layout, and the other two commands aren’t standard for displaying VLAN membership.
