Which of the following are common VLAN link types of Ethernet switches?

VLAN link types define how VLAN traffic is handled on switch ports. The three common VLAN link types are:

Access Ports :

Used to connect end devices (e.g., PCs, printers) to the switch.

An access port belongs to only one VLAN and carries untagged traffic for that VLAN.

Example: A PC connected to an access port in VLAN 10 sends and receives untagged traffic.

Trunk Ports :

Used to connect switches or routers to carry traffic for multiple VLANs.

Trunk ports tag traffic with VLAN IDs using IEEE 802.1Q encapsulation.

Example: A trunk port connecting two switches carries tagged traffic for VLANs 10, 20, and 30.

Hybrid Ports :

A hybrid port can carry both tagged and untagged traffic.

It is flexible and can be used for scenarios where a mix of tagged and untagged traffic is required.

Example: A hybrid port might send untagged traffic for VLAN 10 and tagged traffic for VLAN 20.

Mix :

This is not a standard VLAN link type and does not exist in Ethernet switch configurations.

Thus, the correct answers are A (Trunk) , B (Access) , and C (Hybrid) .
