Huawei Certified Internetwork Expert-Transmission Sample Questions:

1. Regarding the OTN system network-level protection switching test, which of the following statements is correct? ()

A) The power difference between the main and backup channels of the OLP protection group is more than 3dB by default, and the alarm is reported up, and the maximum can be set to 8dB
B) OLP main and standby optical power abnormal threshold exceeds 5dB by default to perform switching, and the threshold range can be set -5~5
C) In the OTN bearer SDH multiplex section ring networking scenario, in order to avoid simultaneous switching of OLP protection and MSP protection, the delay time can be set in the MSP protection group
D) The ODUk-SNCP protection is superimposed on the OLP protection. In order to avoid secondary switching of the SNCP protection, the delay time can be set in the SNCP protection group

2. The EDFA in the OAU board has a gain lock function. When the optical signal of one or several channels or some channels fluctuates, it does not affect the signal gain of other channels.

A) TRUE
B) FALSE

3. Regarding the reporting of the OTUk_BDI alarm, the following statement is wrong.

A) The corresponding OTU board of the downstream station receives OTUk_SSF
B) The downstream station's corresponding OTU board receives OTUk_AIS
C) The downstream station's corresponding OTU board receives OTUk_TIM
D) Only the WDM side port will report OTUk_BDI

4. In the network management planning, which of the following descriptions is correct (multiple choice)

A) Equivalence factor = resources occupied by physical network elements or ports / system resources occupied by equivalent network elements; virtual network elements do not calculate management capabilities; pre-configured network elements are equivalent to virtual network elements.
B) Centralized deployment scheme is recommended for network management deployment planning. Only consider the use of a distributed deployment solution when the customer strongly requires it.
C) Among other requirements, if the client is running on the server side at the same time, the management ability will be reduced by 60%, so it is recommended that the client and server be run separately.
