Switch-1 is an AOS-switch that is operating at factory default settings for QoS and has type of service disabled. It receives a frame with 802.1p value 5 trk1, on VLAN 2. How does the switch treat the frame when it forwards it on trk2?

• A.It forwards it with normal priority and 802 1p 0.
• B.It forwards it normal priority and 802.1p 5.
• C.It forwards it with higher than normal priority and 802. 1p 5.
• D.It forwards it with higher than normal priority and 802 1p 0.
