A.The IP phone access port will override the priority of the frames received from the CK-PC
B.The IP phone access port would trust the priority of the frames received from the CK-PC
C.The switch port FaO/4 would neglect the priority of the frames received from the CK-PC
D.The switch port FaO/4 would trust the priority for the frames received from the CK-PC

A.A PC connected to a switch port via an IP phone is unaware of the presence of the phone
B.The traffic on the voice VLAN must be tagged with 802.1p encapsulation in order to coexist onthe same LAN segment with a PC
C.To improve the quality of the voice traffic， no other devices should be attached to the IP phone
D.The voice VLAN must be configured as a native VLAN on the switch
E.A PC connected to a switch port via an IP phone must support a trunking encapsulation
