A. MUT_LOS
B. OSC_LOS
C. R_LOS
D. OSC_RDI

質問 4：
Which of the following is not a part of the ASON Control Protocol?
A. IS-IS
B. OSPF-TE
C. LMP

正解：A
質問 5：
When configuring the layer 2 attribute of the large network, when the "TAC ID" is set to "Access" or "Hybrid", you need to set the "default VLAN ID" and "VLAN priority" of the untagged frame.
A. TRUE
B. FALSE
正解：A
質問 6：
The main function of the transport layer in the Huawei ECC protocol stack is _____.
A. Provide data communication services.
B. Establish and maintain an ECC routing table.
C. Establish and maintain a MAC connection between neighboring network elements.
D. Provide end-to-end communication services to the upper layer
正解：D
質問 7：
Which of the following description of the performance parameters of line fiber quality monitoring is wrong?
A. The total loss of the fiber will affect the actual detection distance. The dynamic range of the same detection mode is fixed. The larger the total loss of the fiber, the smaller the distance that can be detected.
B. Line fiber quality monitoring function increases the monitoring accuracy by adding the averaged results to the average. The actual time required from the start detection to the software returning the test result will be greater than the "detection time" is set.
C. Increasing the pulse width increases the duration of the laser emission, which increases the energy injected, allowing for a larger dynamic range, but an increase in pulse width results in a larger dead zone.
D. Different modes of light pulse width are different in detection, pulse width affects distance accuracy and monitoring distance. The larger the pulse width, the larger the dynamic range, the longer the test distance and the higher the range measurement accuracy.
