Huawei HCIP-Transmission V2.0 - H31-341-ENU FREE EXAM DUMPS QUESTIONS & ANSWERS]

Question 1

The following description of the use of synchronous methods to create fiber optics, which is wrong?

A. Collision fiber refers to the fiber that is configured on the network element side and is inconsistent with the configuration on the network management side. B. If there is a fiber that is not created on the U2000 or a fiber that is not created on the network element, you need to synchronize or create it. C. The fiber exists on the network management side and the network element side, and the fiber with the same information is not required to be created. D. The existence of a conflicting fiber does not affect the configuration of the path, so it can be ignored.

Question 2

During the process of maintaining the OSN device, it is often seen that the fan runs at full speed, and the device reports the TEMP_OVER alarm. What are the common causes and treatment methods?

A. The dust filter is heavily dusty and affects ventilation. The dust filter needs to be cleaned. B. The optical module has an abnormal cooling function and needs to be replaced with a light board. C. The power module of the board is heavily dusty, affecting heat dissipation, and needs to be removed. D. The dust inside the fan is serious, which affects the speed. You need to remove the fan to remove it.

Question 12

Which of the following description of the principle of automatic protection switching of the standard SSM protocol are correct? (Multiple choice)

A. The network element broadcasts the clock quality information and the clock source ID of the synchronization source through the downstream station between the S1 bytes, and notifies the upstream station that the clock quality from the local network element is "not available for synchronization" by the S1 byte in the direction of the synchronization source. B. According to the clock source priority table, the network element first selects the clock with the highest quality level from the available clock sources as the homologous source. C. The network element broadcasts the clock quality information of the synchronization source to the downstream site through the S1 byte, and notifies the upstream station that the clock quality from the local network element is "not available for synchronization" by the S1 byte in the direction of the synchronization source. D. If there are multiple clock sources with the highest quality level, the network element selects the clock with the highest clock priority as the synchronization source.
