Answer: f

5. Which of the following descriptions of the PQ queue strategy are true? ( )
A.PQ can provide different priorities to different service data packets, and can provide absolute priority to the high priority packet.
B.PQ is used to guarantee the delay of the real-time application sensitive to the time like VOIP.
C.As CQ, PQ needs to be configured, but its processing speed is faster.
D.Because PQ cannot restrict the bandwidth of the high priority packet, the low priority packet may get no bandwidth.
Answer: abd
