Huawei HCIP-Transmission V2.0 H31-341-ENU Prüfungsfragen mit Lösungen:
1. The wave division system complement to chromatic dispersion mainly adopts the DCM compensation method. The following statements about DCM dispersion compensation, which is wrong?
A) Improper configuration of the DCM will result in degradation of the receiving end performance.
B) Improper configuration of the DCM will result in degradation of the system signal-to-noise ratio.
C) The DCM module is more likely to cause nonlinearity than the line transmission fiber, so it is necessary to strictly control its fiber-optic power.
D) 10G system with line fiber length less than 400km, G.652 DCI can be used to compensate G.655LEAF).
2. The main light path monitoring is based on the OMS segment and it mainly monitors which of the following items? (Multiple choice)
A) The origin of the optical discharge power is abnormal
B) Line attenuation exceeds the design EOL value.
C) Line attenuation compensation is abnormal
D) The main light path is broken?
3. TEM28 is the Ethernet convergence tributary board. Which of the following descriptions about the TEM28 board are correct? (Multiple Choice)
A) TEM28 can simultaneously access FE, GE, 10GE LAN and 10GE WAN services through different ports.
B) The TEM28 board supports the L2 switch module and needs to configure the port to VCTRUNK service.
C) The electrical signal can be output ODU0, ODU1flex, 00U1 or ODU2 signals to the backplane for cross scheduling through operations such as encapsulation mapping and OTN framing.
D) RX1/TX1~RX4/TX4 ports are 10GE optical ports, which can handle 10GE LAN/10GE WAN services. Other interfaces are GE optical ports, GE electrical interfaces or FE electrical ports which can handle GE or FE services.
4. The optical monitoring channel wavelength used by the ST2 board is: (Multiple choice)
A) 1471nm
B) 1491nm
C) 1511nm
D) 1510nm
5. Which of the following description of the PWE3 technology are correct? (Multiple choice)
A) For PE3 emulation of Ethernet services, PW control words can be manually configured on the PE.
B) The internal data services carried by PWE3 are visible to the core network.
C) PRE3 technology provides ATM, Ethernet, and TDM services with end-to-end virtual link emulation at the PS network boundary.
D) PWE3 technology belongs to the second layer VLL solution
