The Tag Control Information (TCl) field comprises the following elements:

• Priority

• CFI

• VLAN ID

Which of the following statements are TRUE about the PVID

• The PVID of an access port is the VLAN that it belongs to, and is not configurable.

• Atrunk or hybrid port allows multiple VLANs, and you can set the PVID of a trunk or hybrid port.

• After you use the undo vian command to delete the VLAN that an access port is in, the PVID of the access port changes to VLAN 1.

• After you use the undo vlan command to delete a VLAN which is the default VLAN of a hybrid or trunk port, the default VLAN of the port does not change.

Which of the following statements are TRUE about a trunk port?

• The trunk ports of a switch can connect only to switches.

• A trunk port does not change the VLAN tag of any incoming VLAN tagged frame.

• A trunk port always sends a frame out with its VLAN tag unchanged, regardless of whether the VLAN ID of the frame is the same as the PVID of the trunk port or not.

• To change a trunk port into a hybrid port, you must configure the port as an access port first.
