What is a VLAN interface and how do you assign VLAN ID 10 to the bridge1 interface?

• A. A physical interface that carries multiple VLANs using sub-interfaces
• B. A VLAN interface is a firewall rule for VLANs
• C. A VLAN interface is a virtual interface tagged with a VLAN ID; /interface vlan add name=vlan10 vlan-id=10 interface=bridge1
• D. A VLAN interface is a wireless profile

Answer: (C)

A VLAN interface is a virtual interface that carries traffic for a specific VLAN by tagging frames with a VLAN ID. By creating such an interface and tying it to a bridge, you isolate and route traffic for that VLAN separately from others. To assign VLAN ID 10 to the bridge1, you create a VLAN interface named vlan10 with the VLAN ID set to 10 and attach it to bridge1 using the command: /interface vlan add name=vlan10 vlan-id=10 interface=bridge1. This creates the logical interface that handles VLAN 10 traffic on the bridge. Other options either describe something entirely different (firewall rule, wireless profile) or imply a different physical/sub-interface concept that isn’t how MikroTik’s VLAN interface is defined.
