Refer to the exhibit. A technician is programming switch SW3 to manage voice and data traffic through port Fa0/20. What, if anything, is wrong with the configuration?
- There is nothing wrong with the configuration.
- Interface Fa0/20 can only have one VLAN assigned.
- The mls qos trust cos command should reference VLAN 35.
- The command used to assign the voice VLAN to the switch port is incorrect.
Answers Explanation & Hints:
The voice VLAN should be configured with the switchport voice vlan 150 command. A switch interface can be configured to support one data VLAN and one voice VLAN. The mls qos trust cos associates with the interface. Voice traffic must be trusted so that fields within the voice packet can be used to classify it for QoS.
