Question 7What does the interface subcommand “switchport voice vlan 222” indicate?

A. The port is configured for data and voice traffic.
B. The port is fully dedicated to forwarding voice traffic.
C. The port operates as an FXS telephony port.
D. Voice traffic is directed to VLAN 222.

Answer: A or D


Let’s see an example of configuring this command.


Switch(config)#interface fa0/0
Switch(config-if)#switchport voice vlan 30

The “switchport voice vlan 30” command directs the switch to send CDP packets that configure the IP phone to transmit voice traffic in 802.1Q frames, tagged with VLAN 30. The data traffic is sent to the native VLAN (untagged).

Therefore in this question both answer A and D are correct. I don’t know why we only have one choice in this question.
