Huawei H12-931-ENU FAQs: What Every Candidate Asks
The H12-931-ENU exam, officially titled Huawei Certified Internetwork Expert-Transmission, is the qualifying test for the HCIE-Transmission certification from Huawei, a credential at the Expert level. Passing it proves you have the skills employers look for in certified professionals, and it can also support progress toward related credentials such as HCIP-Transmission (H31-341), HCNA-Transmission (H31-311).
The Huawei Certified Internetwork Expert-Transmission exam gives you 90 minutes to work through 60 questions. That is a steady pace with little room for second-guessing, so train yourself to read each question once, flag the difficult ones, and keep moving. Before exam day, sit at least two full timed sessions in the GuideTorrent test engine — when the clock feels familiar, it stops being a threat.
You need 600/1000 to pass, and the official registration fee is USD $300. Fall short and you pay that fee in full again for every retake, which makes solid preparation the cheaper option by far. Work through the GuideTorrent practice questions until you score comfortably above the passing mark, then book your seat.
Recommended hands-on transmission network experience and prior HCIP/HCNA certifications. Eligibility rules can change over time, so before you register, confirm the latest requirements on the official exam page: Huawei H12-931-ENU exam overview.

Correct Answer: A,B,C,E 🗳️
After which of the following steps, the rollback operation can no longer be performed
- A. Activate
- B. Load
- C. Distribution
- D. Submit
Correct Answer: D 🗳️
When the MR1 board is used as an OSN1800 single fiber bidirectional in the following scenarios, you can use the MR2 or MR4 board instead
- A. TRUE
- B. FALSE
Correct Answer: B 🗳️
Which of the following statements about the ALC function and configuration principles of the OTN system is correct? () (multiple choice)
- A. 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
- B. The detection and reference unit of the first node cannot use the same optical port of the same board
- C. 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
- D. 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
- E. 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
- F. Each ALC link has a unique ID, and ALC nodes can belong to different DCN subnets
Correct Answer: B,C,D,E,F 🗳️
What should be paid attention to when planning a 1588V2 network?
- A. 1PPS + TOD interface is more suitable for internal transmission of the network
- B. It is recommended to adopt BC mode for the whole network in the networking mode
- C. In practical applications, there may be a distance difference between the two directions of the fiber optic transceiver, but there is no need to compensate for this. 1588V2 will automatically calculate it according to the algorithm
- D. BMC algorithm must be activated to prevent looping
