Huawei Certified Internetwork Expert-Transmission Sample Questions:

1. When relocating the OLA site (10G system), which of the following descriptions are wrong

A) There is no need to adjust the optical power of upstream and downstream sites in the network management during the relocation process
B) The relocation distance has changed and the system signal-to-noise ratio needs to be reassessed
C) The relocation distance has changed, and the system dispersion needs to be re-evaluated
D) The relocation distance has changed, and the optical power of the line needs to be reassessed

2. The optical power of one wave is 3dBm, and the optical power of the other wave is 5dBm. The total optical power after the two waves are combined is 3+5 = 8dBm

A) FALSE
B) TRUE

3. The interface board N1SF64 of OSN 7500 and the A1SF64 of OptiX 10G (Metro 5000) support different protocols, so they cannot be connected.

A) FALSE
B) TRUE

4. A certain network is configured with SOM. When performing path performance analysis, the OSNR value of the downstream optical amplifier of the OCh path is higher than that of the upstream optical amplifier. What is the error of the following analysis ()?

A) After the initial configuration of the SOM route is issued, the performance analysis is started immediately. If the SOM route is configured first in the OMS section at this time, the OSNR calculation is started first, and there is no basis for the previous OSNR calculation value, this phenomenon will occur
B) Click "Analyze" on the "Path Performance Analysis" interface to restart the performance analysis to solve the problem
C) The calculation of the OSNR value of the first part of the OMS section where the OCH path is located is completed, and the calculation of the latter part has not been started. At this time, the performance analysis is started, and the new calculated value of the front part is reduced due to external reasons. This phenomenon will occur
D) The network management must issue the SOM routing configuration to the OMS segment on the path in order from the front to the back. It takes about a few seconds to issue the SOM routing configuration for each OMS segment, and it takes a few seconds to configure the SOM routing existence time between each OMS segment. difference

5. The scope of 1+1 protection in the OTU board is the optical fiber on the OCH path, that is, the optical fiber between the dual transmission of the source OTU single board and the selective receiving of the sink OTU single board. Cannot protect OTU board

A) FALSE
B) TRUE
