What describes an access port on a switch?

• A. A port that connects multiple VLANs
• B. A port that belongs to a single VLAN
• C. A port that routes between VLANs
• D. A port used for management purposes

Answer: (B)

An access port on a switch is specifically configured to belong to a single VLAN, which is a crucial aspect of how VLANs function in a network. This means that any device connected to that port will only be able to communicate with devices within the same VLAN. Access ports are typically used to connect end devices, such as computers or printers, where the data traffic does not require VLAN tagging. This single VLAN membership allows the switch to segregate traffic and manage bandwidth efficiently, ensuring that devices communicate with other devices in their VLAN without unnecessary exposure to traffic from other VLANs. In contrast, trunk ports, which are different from access ports, are used to carry traffic for multiple VLANs by allowing VLAN tagging on the data frames.
