Huawei H31-341-ENU 問題集

質問 1：
Which of the following are limitations of the alarm and performance analysis methods? (Multiple Choice)
A. The network administrator cannot obtain the current notifications of the device, the alarm occurrence time, and the historical alarm of the device.
B. Field maintenance personnel cannot understand the current operating condition of the equipment.
C. 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.
D. When some faults occur, there may be no obvious alarms or performance events reported, and sometimes no alarms or performance events are found.
正解：C,D

質問 2：
The length range of the DATA field in the Ethernet frame structure is ().
A. 46-1500 bytes
B. 46-1518 bytes
C. 64-1500 bytes
D. 64-1518 bytes
正解：A

質問 3：
Customer Example 1+1 protect when using different routes, the same wavelength cannot be used for the working wavelength and the guard wavelength.
A. FALSE
B. TRUE
正解：A

質問 4：
The OCh path is created using the single station method. After the creation is completed, the 0ch path is not searched. Which are the possible reasons? (Multiple choice)
A. Inconsistent wavelengths of the line boards at both ends of the source and sink
B. Line attenuation is too large
C. errors in source and sink ports in the site
D. Missing logical fiber between sites
正解：A,D

質問 5：
Which of the following description of the extended ECC is correct? (Multiple Choice)
A. In the automatic extended ECC mode, you need to connect the Ethernet ports of the two NEs with a direct-connected network cable (or a standard network cable through B), extend the ECC, and specify the server and client.
B. Extended ECC is divided into automatic extended ECC and manual extended ECC. One network element can only support one mode at the same time. These two methods cannot be directly docked.
C. The scale of the extended ECC network (the sum of the server and the client) must not exceed 8.
D. Extended ECC recommends to use manual basis, which reduces mutual negotiation between network elements.
正解：B,C,D

質問 6：
As with the STP device, the NG WDM device can practice the network element configuration on the network through pre-configured method.
A. FALSE
B. TRUE
正解：A

質問 7：
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 9 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. FALSE
B. TRUE
正解：B
