What type of port is also known as a 'tagged' port in VLAN configurations?

• A. Access port
• B. Trunk port
• C. Management port
• D. Uplink port

Answer: (B)

In VLAN configurations, a trunk port is known as a 'tagged' port because it carries traffic from multiple VLANs simultaneously and uses VLAN tagging to identify the source of the traffic. The trunk port adds a VLAN identifier to each Ethernet frame transmitted over the link, which allows switches and routers to recognize and segregate traffic belonging to different VLANs. This is crucial in environments where multiple VLANs operate on the same physical network infrastructure. In contrast, an access port is configured to carry traffic for a single VLAN and does not utilize tagging; consequently, Ethernet frames moving through it do not contain VLAN information. Management and uplink ports are not specific types of ports defined by VLAN tagging; rather, they serve other purposes in network architecture. The functionality of a trunk port allows for efficient and organized management of VLAN traffic across network devices.
