Huawei Certified Internetwork Expert-Transmission 認定 H12-931-ENU 試験問題：

問題 #1

The reason why the ODUk_PM_OCI alarm statement is correct (multiple choice)

A. This alarm will not cause interruption of the optical interface carrying service
B. The corresponding board of the opposite station is not configured with crossover and the non-intrusive monitoring function is enabled on the local end
C. Loopback is set for the corresponding board of the opposite station
D. The board corresponding to the upstream site has an ODUk_PM_OCI alarm

問題 #2

Which of the following statements about the ALC function and configuration principles of the OTN system is correct? () (multiple choice)

A. The ALC function can automatically adjust the output optical power of the amplifier in which the line attenuation changes. Except for the first site, other sites must be equipped with power detection units
B. If there are two cascaded OA boards in the node, the first node only configures the second OA board as the reference unit, and do not deploy the power detection unit
C. The detection and reference unit of the first node cannot use the same optical port of the same board
D. Each ALC link has a unique ID, and ALC nodes can belong to different DCN subnets
E. The "working mode" of the OA board and RAU1/RAU2 board must be configured as "gain lock", if it is configured in other modes and ALC is configured, the ALC will not be adjusted
F. It is recommended that the number of network elements in the ALC link is less than 20, otherwise the ALC adjustment may time out and cause failure

問題 #3

When the return loss is too low, it is strictly forbidden to turn on the RAMAN laser, but when the return loss is too high, it is possible to turn on the RAMAN laser.

A. TRUE
B. FALSE

問題 #4

When planning AM, you need to consider the priority planning of E1. Which of the following options are the planning principles of E1 priority (multiple choice)

A. When the E1 priority function is enabled, E1 service bandwidth under full capacity ≤ full capacity service bandwidth-guaranteed capacity service bandwidth + E1 service bandwidth under guaranteed capacity.
B. The E1 priority function is mainly used in the scenario of Hybrid microwave transmission IMA service. At this time, the guaranteed E1 capacity should be equal to the E1 capacity required by IMA to transmit high-priority services; the full-capacity E1 capacity should be equal to the E1 capacity used by IMA.
C. The priority set when an E1 service passes through a multi-hop microwave link can be different.
D. The priority of the E1 service has nothing to do with the time slot number of the IF board it occupies, but the priority is specified when the cross-connection of the E1 service is configured. There are two types of E1 priority: high and low.

問題 #5

The OAU105 single board of the OTN system has a maximum output power of 23dBm, and the maximum output power of a single wavelength in the 40-wavelength system can be calculated to be 4dBm

A. TRUE
B. FALSE
