Huawei Certified Internetwork Expert-Transmission Sample Questions:

1. The OSN 8800 equipment enhances the relationship between the front and back of the PIU slots of the subrack as the primary and backup slots. Which of the following is the correct relationship between the primary and backup slots? () (multiple choice)

A) 69 and 78
B) 78 and 81
C) 79 and 80
D) 69 and 89
E) 70 and 79
F) 70 and 88

2. The test frame is a data message used to test the network connection status of the Ethernet service. Regarding the application of the OTN equipment test frame, which of the following statements is correct? () (multiple choice)

A) For GE/FE/10GE LAN services, the GFP management frame is used to send test frame messages. The test frame has two counters, which are used to count the sent and received test frames.
B) For 40GE/100GE services, test frame messages are sent directly at the MAC layer. There are three counters for test frames, which are used to count sending test frames, answering test frames, and receiving test frames.
C) For the optical wavelength conversion board with the transceiver integrated, the test frame has nothing to do with whether the board is configured with electrical crossover.
D) When the client side accesses 10GE LAN services, "Port Service Mapping Path" needs to be set to "MAC Transparent Mapping (10.7G)" to support the test frame function
E) When the tributary board is configured to be electrically crossed to the wavelength division side of the optical wavelength conversion board that supports the test frame, the GFP management frame is processed by the optical wavelength conversion board. Therefore, in this case, the tributary board cannot send and receive test frames

3. The function of PW OAM is basically the same as that of Tunnel. The PW OAM mechanism can effectively detect, confirm and locate defects and faults originating from the PW layer network.
Which of the following functions are not available in PW OAM?

A) Ping
B) BDI
C) LB
D) FDI

4. OptiX OSN 1800 is a compact multi-service optical transport platform. What is wrong in the following description? ()

A) The maximum rate of a single channel is 10 Gbit/s (OTU2)
B) 1588v2 transmission is not supported, and external time signal access is not supported
C) The OptiX OSN 1800I chassis provides a total of 4 service single board slots
D) OptiX OSN 1800II chassis provides a total of 8 service single board slots

5. Is the following statement about the delay test wrong? ()

A) In the time delay test, the frame rate can be greater than the throughput
B) Delay is divided into the delay of storage and forwarding equipment and the delay of bit forwarding equipment. Huawei equipment is all storage and forwarding equipment.
C) The last bit of the data frame enters the device to start timing, and the first bit of the data frame appears at the end of the output port. The time difference between the two is the delay of the store and forward device.
D) The time from the first bit of the data frame to the beginning of the time until the first bit of the data frame appears on the output port, the time difference between the two is the delay of the bit forwarding device
