Free Huawei H31-341-ENU Exam Dumps Questions & Answers

The following description of the Directioned scenario, which is correct? (Multiple choice)

• A.When the service needs to be adjusted, or the working path is faulty, the optical crossover can be manually configured to implement flexible scheduling of services.
• B.Directioned scenes are applied to networks that are not ASON.
• C.If the current path needs to be adjusted, you must inbound to adjust the fiber connection of the network.
• D.The wavelength carrying the local service can be transmitted to fixed direction.

The NG WDM two-dimensional ROADM site can use the WSMD9 single board, and its signal flow is an optical signal that is connected to the main optical channel from the "IN" optical port. The RDU (ROADM Demix Unit) optical module broadcasts nine identical optical signals, which are output from the "DM1~DM8" and "ECPO" optical ports respectively. One of the signals is localized by the splitter board, and the other eight signals are dispatched to the other eight directions. Each wave of the main optical channel is connected from the "EXPI" optical port. The multiplexed or single-wave optical signal that needs to be inserted locally is input through the "AM1"~"AM8" optical port.

• A.TRUE
• B.FALSE

Which of the following are not part of the 400G originating modulation technology?

• A.FDDM/Nyquist spectrum compression technology
• B.Advanced oDSP algorithm
• C.Multi-carrier generation and multiplexing
• D.High-order modulation (xQAM)

The following limitations of alarm and performance analysis methods are: (Multiple Choice)

• A.In the case of complex networking, service, and fault information, many alarms and performance events may occur along with the occurrence of faults. Due to too many reports and performance events, maintenance personnel are unable to analyze.
• B.The network administrator cannot obtain any alarms, time, and historical alarms of the device.
• C.When some faults occur, there may be no obvious alarms or performance events reported, and sometimes no alarms or performance events are found.
• D.Field maintenance personnel cannot understand the current health of the equipment.

FOADM includes parallel FOAD and serial FOADM, both supporting 40 waves or 80 waves of arbitrary wavelengths.

• A.TRUE
• B.FALSE
