Huawei H31-341 Online Questions & Answers

• Question 31:

  For the MSTP equipment, the pass-through mode is used for VC-4 services by default, and the termination mode is used for VC12/VC3 services by default.

  A. True
  B. False
  A. True

• Question 32:

  Which of the following is not included in an ASON network?

  A. ASON Domain
  B. ASON NE
  C. SC
  D. TE Link
  D. TE Link

• Question 33:

  In a WDM system, after a distance of transmission, the OSNR of the signals at the receive end decreases to a certain extent. Which of the following is the main cause?

  A. Use of EDFA
  B. The fiber attenuation is too large.
  C. New optical fiber is not used.
  D. Use of Demultiplexer Multiplexer
  B. The fiber attenuation is too large.

• Question 34:

  Which of the following statements about the line fiber quality monitoring performance parameters is wrong?

  A. The pulse width of emitted optical pulses varies according to monitoring modes, and affects the detection distance and measurement precision. A greater pulse width provides a larger dynamic range, longer detection distance and better measurement precision.
  B. When the pulse width increases, the light emitting time increases and consequently a larger energy is obtained. This means that a larger dynamic range can be acquired but also larger dead zones will result.
  C. Measurement is performed multiple times within the detection time. The average value is obtained based on the measurement results to improve the measurement precision. The actual duration from the time when a detection event starts to the time when the detection results are returned will be longer than the Detection time.
  D. The total fiber loss will affect the detection distance and the dynamic range is fixed for the same detection mode. Therefore, a larger total fiber loss indicates a smaller detection distance.
  D. The total fiber loss will affect the detection distance and the dynamic range is fixed for the same detection mode. Therefore, a larger total fiber loss indicates a smaller detection distance.

• Question 35:

  Which of the following is the client-side logical port of a board in standard mode?

  A. ODUkLP-n
  B. RX/TX-n
  C. ClientLP-n
  D. n(Nn/OUTn)-OCH:l-ODUk:m-ODUp:q
  A. ODUkLP-n

• Question 36:

  The overhead ratio is a factor that affects the error correction capability of the FEC technology. Generally, when the same FEC encoding/decoding algorithm is used, the higher the overhead ratio is, the larger the net coding gain is.

  A. True
  B. False
  B. False

• Question 37:

  Which of the following statements about AU pointers are correct?

  A. The root cause of the AU pointer justification is that the clocks of the upstream and downstream stations are not synchronized.
  B. AU-PTR indicates the position of the JO byte.
  C. If the receive end detects that the H1H2 bytes are "1", the local end generates the AU-AIS alarm.
  D. The value of the AU-PTR pointer is placed in the last 10 bits of the HI and H2 bytes. Therefore, the valid value of the AU-PTR pointer is 0-1023.
  D. The value of the AU-PTR pointer is placed in the last 10 bits of the HI and H2 bytes. Therefore, the valid value of the AU-PTR pointer is 0-1023.

• Question 38:

  When the standard Ethernet frame whose length is 64 Bytes is accessed to the Ethernet board, if the QinQ function is enabled, what is the actual frame length of the signal in the board? ( )

  A. 80 Bytes
  B. 84 Bytes
  C. 64 Bytes
  D. 68 Bytes
  D. 68 Bytes

• Question 39:

  If the LED indicator value on the SCC board of the OSN 8800 T32 board is 11, which of the following is the subrack ID?

  A. Slave subrack 2
  B. Slave subrack 1
  C. Slave subrack 17
  D. Slave subrack 11
  D. Slave subrack 11

• Question 40:

  Dispersion compensation is not required for 40 Gbit/s and 100 Gbit/s coherent systems because the dispersion tolerance of coherent boards is large. NG WDM products do not support hybrid transmission of non-coherent and coherent networks.

  A. True
  B. False
  B. False
