When troubleshooting in a local area network, you notice that there are a large number of frame alignment False, FCSFalse and Lag of conflict.
what is the possible reason to cause this problem?
A. switch and terminal by 10/100/1000Base-T Ethernet link connected, and the working mode of the switch and terminal is half duplex
B. in most of the environment all have such False
C. working mode on 1000Base-LX/LH link don’t match
D. Working mode on 10/100/1000Base-T Ethernet link don’t match
Which of the following is only used for BGP to choose routing? (Multiple choice)
You’re troubleshooting frame relay interface serial 0 on HW router. When the interface is up and quickly enters the down state. You use the command display interface, see LMI status message of interface serial has been sent but not received.
So what causes the problem occur?
A. Receive too much error message on the link
B. Frame Relay Imi-type configuration error
C. Subinterface number exceeds the limits of the IDB
D. DCD configuration errors on the frame relay line
E. Ends of keepalive configuration error
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
Which of the following can be used for BGP routing? (Multiple choice)
Which of the following description about data traffic load sharing in Huawei equipment is true?
A. only LACP and LLDP protocol in Huawei devices can implement data traffic load sharing.
B. Huawei device supports PoS, Serial, Ethernet and other types of interface link aggregation and load sharing.
C. under the Huawei switches Eth-trunk interface, the default is based on source MAC address and destination IP address foreignlands for load sharing.
D. under Huawei switches Eth-trunk interface may be based on data frame CoS values do hash algorithm to achieve load sharing.
