Huawei Certified Internetwork Expert-Transmission 認定 H12-931-ENU 試験問題:
1. 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) BDI
B) Ping
C) FDI
D) LB
2. Four network elements A, B, C, and D form an SNCP ring, and there are a large number of PDH services between A and B.
One day, the fiber between A and B was interrupted.
In order to eliminate the R-LOS alarm on the network management system, an engineer self-looped the optical ports at both ends of the interrupted fiber. After 10 minutes by default, what will happen?
A) The service between A and B is interrupted, and the switching alarm disappears
B) The services of A and B will not be affected, and the switching alarm will not disappear
C) The business between A and B is not affected, and the switching alarm disappears
D) The service between A and B is interrupted, and the switching alarm does not disappear
3. Which of the following statements about the configuration, testing and maintenance of IP functions are correct? () (multiple choice)
A) The purpose of testing the IPA function is to verify that if any fiber is broken in the fiber path included in the IPA, the amplifier included in the IPA can be turned off. After the fiber is restored, the amplifier can be turned on automatically, and Power change within 0.5dB
B) After the IPA function is successfully activated, when the amplifier board detects LOS, the optical power of its output port becomes safe optical power. Select "Configuration/IPA Management" in the function tree of the network element manager, and you can configure IPA to start Delay value
C) When the fiber interruption is repaired and the IPA cannot be terminated, it may be because the IPA protection group is not configured with a "detection board", only the auxiliary detection board is configured, and the auxiliary detection board reports an alarm that triggers IPA
D) IPA function is only applicable to Raman amplifiers, not to ordinary amplifiers
4. The ring network of the OSN6800 equipment group was newly opened, and ODU1-SNCP/N protection was enabled. The engineer reported that a switch occurred one day and has not been restored, but there is no problem with the optical cable. There is an ODU_SNCP_PS alarm on the corresponding ND2 optical port.
Possible reasons are: (multiple choices)
A) Related circuit board failure
B) "LCK Insert" is set to enable the PM overhead of the related circuit board
C) The related circuit board has a minor alarm ODU1_PM_LCK
D) The protection type is configured as SNC/I
5. The type of software to be loaded in the OSN product upgrade process includes the basic BIOS. Then, what are the main functions of the basic BIOS? (multiple choice)
A) Support FPGA upgrade and loading
B) Complete hardware initialization, operating system startup and initialization
C) Boot the host/single board software to start
D) Support the loading and upgrading of host/single board software
