What’S the problem with the man’s place now? 

A . #!/bin/ksh line is missing B . Variable name VAR is not properly initialized C . Loop variable is not incremented inside the loop D . Replace brackets with brace

A . The minimum data rate is not set to 11 Mbps. B . An address resolution protocol is enabled. C . Publicly Secure Packet forwarding is enabled. D . The access point is set to the least congested channel.

A . Variable queue delays B . Packet drops C . Transmitting too many small packets D . Compressio

A . Queuing introduces equal delays for packets of the same flow， resulting in jitter. B . When congestion occurs， dropping affects most of the TCP sessions， which simultaneously back off and then restart again. C . All buffers can temporarily be seized by aggressive flows， and normal TCP flows experience buffer starvation. D . There is no differentiated drop mechanism. Higher priority traffic is dropped in the same way as best-effort traffic. E . In TCP starvation， traffic exceeds the queue limit because of the bursty nature of packet networks. A router cannot handle multiple concurrent TCP sessions. F . Global synchronization occurs because multiple TCP hosts reduce their transmission rates at random intervals in response to packet dropping

A . The minimum data rate is not set to 11 Mbps. B . An address resolution protocol is enabled. C . Publicly Secure Packet forwarding is enabled. D . The access point is set to the least congested channel.
