In a network, all routers deploy FIFO queuing. The primary application running on the network is data backup by use of FTP. At certain times, users experience cyclical performance degradation. Which two items can mitigate this problem and help ensure bandwidth is used effectively in the network? (Choose two.)
A) traffic policing
B) CB-WFQ
C) MDRR
D) WRED

CB-WFQ (Class-Based Weighted Fair Queuing) can help by providing bandwidth guarantees to different traffic classes, ensuring that critical applications like FTP have enough resources. WRED (Weighted Random Early Detection) can prevent congestion by dropping packets early, thus avoiding buffer overflow and ensuring smoother traffic flow.
