Huawei Certified Internetwork Expert-Transmission Sample Questions:

1. OAU gain is continuously adjustable, and the noise figure (NF) is different under different gain conditions, generally the larger the gain, the smaller the noise figure

A) TRUE
B) FALSE

2. Network elements A, B, and C are OSN 3500 forming a chain network. The two stations A and C are connected to routers. The IP routers are connected to the OptiX SDH equipment through the POS port of STM-1. The PAS port connects J1 and C2 bytes. It is also used as a payload to transfer bytes (used to carry services). The network element A to the network element C creates a VC4 service, and the network element B uses VC4 to pass through.
In this case, is there an alarm report inside the SDH network?

A) No warning
B) There is a C2 mismatch alarm
C) There is a J1 mismatch alarm
D) There is a C2 not loaded alarm

3. Which of the following are performance related to SM segment errors

A) OTUk_BBE
B) OTUk_SM_FEBBE
C) OTUk_PM_BBE
D) OTUk_SM_FEES

4. Suppose there are subnets A1, A2, and A3 under subnet A.
When configuring monitoring settings, if subnets A1, A2, and A3 are not all selected for monitoring, subnet A will not be monitored.
If a new subnet A4 is added under subnet A, the newly added subnet A4 will be monitored only when subnet A is monitored, and the monitoring strategy can be different from the monitoring strategy of subnet A.

A) TRUE
B) FALSE

5. The following about system OSNR commissioning errors are

A) One of the principles of the OSNR flatness commissioning of the MPI-R point system: After the pump power is determined, the OSNR flatness of the MPI-R point is detected by a spectrometer, if the OSNR flatness is not up to standard (OSNR flatness index ≤ 2dB) , You need to adjust M40V
B) Adjust the single-wave flatness first, and then adjust the optical power of the main line
C) APE automatically adjusts the optical power of each channel to ensure that the optical power of the receiving end is flat, thereby ensuring a flat OSNR
D) The multiplexer is an M40V single board, "watching the receiving end, modulating the end", while ensuring that the optical power flatness meets the index requirements, the optical power flatness can be sacrificed to ensure the flatness of the OSNR (or BER)
