Which method does a connected trunk port use to tag VLAN traffic?

  • A. IEEE 802.1w
  • B. IEEE 802.1D
  • C. IEEE 802.1Q
  • D. IEEE 802.1p
Answer: Option C.

IEEE 802.1Q is the networking standard that supports virtual LANs (VLANs) on an Ethernet network. When a frame enters the VLAN-aware portion of the network
(a trunk link, for example), a VLAN ID tag is added to represent the VLAN membership of that frame. The picture below shows how VLAN tag is added and removed while going through the network.
