What is the effect when the switchport priority extend cos 3 command is configured on the switch port interface connected to the IP phone？（）
A. The IP phone is enabled to override with aCoS value of 3 the existing CoS marking of the PC attached to the IP phone.
B. The switch will no longer tag incoming voice packets and will extend the trust boundary to the distribution layer switch.
C. RTP will be used to negotiate aCoS value based upon bandwidth utilization on the link.
D. Effectively， the trust boundary has been moved to the PC attached to the IP phone.
