Which statement about a switch port configured as an access port is true?

• A. A trunk port carries traffic for multiple VLANs using tagging.
• B. An access port carries traffic for multiple VLANs using 802.1Q tagging.
• C. An access port is primarily used for uplink connections between switches.
• D. An access port is assigned to a single VLAN and typically connects to end devices with untagged frames.

Answer: (D)

Access ports are designed to connect end devices to a single VLAN. They do not tag frames; frames leaving an access port are untagged, and the switch associates each frame with that one VLAN. This is different from trunk ports, which carry traffic for multiple VLANs by tagging frames with VLAN IDs (802.1Q). Therefore, the true statement is that an access port is assigned to a single VLAN and typically connects to end devices with untagged frames. Uplink connections between switches are usually trunk ports, and an access port does not handle multiple VLANs.
