Which two characteristics describe the native VLAN? (Choose two.)

  • Designed to carry traffic that is generated by users, this type of VLAN is also known as the default VLAN.
  • The native VLAN traffic will be untagged across the trunk link.
  • This VLAN is necessary for remote management of a switch.
  • High priority traffic, such as voice traffic, uses the native VLAN.
  • The native VLAN provides a common identifier to both ends of a trunk.
    Answers Explanation & Hints:

    The native VLAN is assigned to 802.1Q trunks to provide a common identifier to both ends of the trunk link. Whatever VLAN native number is assigned to a port, or if the port is the default VLAN of 1, the port does not tag any frame in that VLAN as the traffic travels across the trunk. At the other end of the link, the receiving device that sees no tag knows the specific VLAN number because the receiving device must have the exact native VLAN number. The native VLAN should be an unused VLAN that is distinct from VLAN1, the default VLAN, as well as other VLANs. Data VLANs, also known as user VLANs, are configured to carry user-generated traffic, with the exception of high priority traffic, such as VoIP. Voice VLANs are configured for VoIP traffic. The management VLAN is configured to provide access to the management capabilities of a switch.
