What type of VLAN supports untagged traffic?
- native VLAN
- voice VLAN
- security VLAN
- management VLAN
Answers Explanation & Hints: The type of VLAN that supports untagged traffic is the native VLAN. The native VLAN is a VLAN that carries untagged traffic, meaning it does not have an 802.1Q tag. By default, the native VLAN on a Cisco switch is VLAN 1, but it can be changed to any other VLAN. The native VLAN is used for communication between switches or between a switch and an end device that does not support VLAN tagging.
