What is an access port?

• A. Port assigned to a single VLAN, typically to a host/server NIC.
• B. Port that carries multiple VLANs tagged.
• C. Port used for management only.
• D. Port used for uplink to another switch.

Answer: (A)

An access port is a switch port configured to belong to a single VLAN and to send/receive untagged frames. It’s the connection you use for end devices like a host or server NIC, so every frame on that port is treated as part of that one VLAN. This is different from a trunk port, which carries multiple VLANs by tagging frames (802.1Q) as they traverse the link. A port used for management is a separate idea, not about assigning a host to a VLAN, and an uplink to another switch is typically a trunk to carry several VLANs between switches.
