F. RED is effective with UDP-based traffic.
Answers: A, D, E. Random Early Detection (RED) does drop packets before the queue is completely full - that's where the "early detection" part comes in! RED doesn't take IP Precedence or CoS into account - that's where the "random" part comes in! : )
Both RED and WRED (Weighted Random Early Detection) are valid only with TCP-based traffic.
