Which port type is used to connect end-user devices and carries untagged frames?

• A. Trunk Port
• B. Edge Port
• C. Access Port
• D. Hybrid Port

Answer: (C)

End-user devices connect to a switch through a single VLAN and expect untagged frames. That’s exactly what an access port provides: it belongs to one VLAN and forwards frames without VLAN tags. This makes it the natural choice for connecting PCs, printers, and other user devices. If you used a trunk port, frames would be tagged to indicate multiple VLANs, which is meant for inter-switch links, not for typical device connections. A hybrid port can carry both tagged and untagged traffic, adding complexity that isn’t necessary for standard end-user devices. An edge port is a term used for ports connected to end devices with features like PortFast, but it doesn’t specifically define untagged frame handling the way an access port does.
