A switch link that can carry multiple VLANs
A switchport that normally belongs to one VLAN for endpoint traffic
The VLAN associated with untagged traffic on an 802.1Q trunk
The setting that restricts which VLANs a trunk may carry
⚠ Common exam trap
Candidates often confuse terms like 'access port' and 'trunk port' or mistake protocols (802.1Q) and properties (native VLAN) for port types. Focus on the function: trunk ports carry multiple VLANs; access ports carry one; 802.1Q is the tagging method; native VLAN is the untagged VLAN on a trunk.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
Trunk port: Carries traffic for multiple VLANs using tagging
These terms define how switchports handle VLAN traffic in trunking environments.
Answer analysis
For each option: why learners choose it and why it is or isn't the right answer here.
Trunk port: Carries traffic for multiple VLANs using tagging
Why this is correct
A trunk port carries traffic for multiple VLANs simultaneously by tagging frames with 802.1Q VLAN identifiers.
Access port: Carries traffic for a single VLAN
Why this is correct
An access port forwards traffic for a single VLAN without tagging.
Native VLAN: Untagged traffic on a trunk port
Why this is correct
The native VLAN is the VLAN that carries untagged traffic on a trunk port. It must match on both ends of the trunk and is typically used for management or CDP/VTP traffic.
VLAN tagging: Adding 802.1Q header to identify VLAN membership
Why this is correct
VLAN tagging adds an 802.1Q header to Ethernet frames to identify VLAN membership, allowing multiple VLANs to traverse a trunk link.

Key term
Switchport
A switchport is a physical or virtual interface on a network switch that connects devices like computers, printers, or other switches to a local area network.
Key term
