Why is QoS important in a converged network?()
A

Because voice data packets must follow a single dedicated path through the network

B

Because voice data packets should arrive quickly and sequentially, and with no lost data

C

Because lost voice-data packets must be retransmitted

D

Because data does not need to arrive intact, so data transfer rates can be variable
