Question:
Which type of VLAN is used to designate which traffic is untagged when crossing a trunk port?

• data
• default
• native
• management

Explanation: A native VLAN is the VLAN that does not receive a VLAN tag in the IEEE 802.1Q frame header. Cisco best practices recommend the use of an unused VLAN (not a data VLAN, the default VLAN of VLAN 1, or the management VLAN) as the native VLAN whenever possible.
