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) .
