DRAG DROP
Drag each of the QoS mechanism on the left to match the correct description on the right. (Not all options on the left are used.)
Answer: 
Explanation:
Can drop express traffic beyond the committed rate and remark non coming traffic before
transmitting it—traffic policing
Use to avoid the TCP global synchronization problems that occur when tail drop is used as the
congestion avoidance mechanism—WRED
Provide a strict priority queue to allow delay-sensitive data such as voice t be dequeued and sent
first–CBWFQ
Express traffic beyond the committed rate will be queue and scheduled for later transmission .Only
applied in the output directions.—traffic shaping
