최신 HCIP Transmission H31-341_V2.5 무료샘플문제:
1. Which of the following description about the TNG2WSMD9 single board are correct? (Multiple choice)
A) The board supports optical power adjustment and online optical power detection
B) The WSMD9 single board belongs to the dynamic optical add-drop multiplexing unit
C) Realize the optical layer level signal service scheduling of multiple wavelengths
D) 9-port wavelength selective multiplexing board (ultra-wide C-band)
2. In daily maintenance scenarios, reset is one of the common operations. Which of the following descriptions about resetting a board is wrong?
A) Long press the RST button on the main control board to realize soft reset
B) Soft reset can only be realized through network management
C) Hard reset can be realized through network management
D) Hard reset is similar to plugging and unplugging a single board
3. For OSN series equipment, what alarm will be reported when one of the PIUs is not connected to the power supply?
A) POWER_DIFF_OVER
B) OWER_ABNORMAL
C) POWER_FAIL
D) BD_STATUS
4. Which of the following description about QPSK modulation technology is wrong? (Multiple choice)
A) EPDM-QPSK is the best solution for 100G WDM transmission.
B) The essence of QPSX is to reduce the baud rate of the optical signal by half without reducing the line rate by selecting two possible values for the phase of the optical field.
C) Through QPSK, one phase represents 2 digital bits, which is equivalent to the processing of "1 is divided into 2" for the data, and the rate is reduced by half.
D) QPSK modulation can increase the spectral bandwidth, reduce the OSNR requirements of the system and the damage of fiber nonlinearity, and improve the dispersion tolerance and PMD tolerance.
5. The scope of management of OMSn is the path from the input optical port on the multiplexer unit at the sending site to the output optical port on the demultiplexer unit at the receiving site. It is called the optical multiplex section (OMS) path.
A) True
B) False
