Answer: ABC

auto-negotiation mode is to obtain maximum interface rate and the operating mode, the network administrator will set all Ethernet interface rate of a workgroup switch to 100Mbps, operating mode configured to full-duplex. When a NIC is configured to auto-negotiation of the workstation is connected to the switch, the outcome of consultations is that the interface rate is 100Mbps, the operating mode is half-duplex.
For this phenomenon, which of the following explanation is the most reasonable?
A. At higher port speed and operating mode, the workstation's network interface card can¡¯t be configured to auto-negotiation
B. port rate negotiation consultations through the initial port to send FLP to negotiate, work mode does not negotiated by FLP
C. when STP in initialization will make the port enter the blocking state, leading to auto-negotiation fails, so the port should be configured to portfast
D. does not configure auto-negotiation on the switch, leading to the swtich can't send the FLP information to the workstation, thereby causing the work station set its own oerating mode to haIf-duplex
E.problem lies in the workstation's network card, most due to the workstation NIC drivers too old, leading to the interface on the workstation NIC learning rate and the operating mode switch configuration
Answer: D

C. IP Experimental ECN
D. DSCP is set as decimal 5
E. Bit Stream 101110
Answer: E
