質問 # 44
Regarding the description of OSS, which is wrong?

A. The U2000 supports multiple northbound interfaces such as SNMP, TL1, XML, and DCORBA, which can realize rapid integration with the operator's OSS system.
B. The network layer of the OSS is above the NMS, and the management of network element devices is generally implemented through the NMS.
C. The OSS system is mainly used to improve the work efficiency of equipment maintenance personnel
D. OSS system (Operation Support System) refers to a software system that provides operators with functions such as communication equipment performance management, inventory management, business management, and fault management.

正解：B

質問 # 45
The unprotected chain consists of four network elements: NE1.NE2.NE3 and NE4. Create an end-to-end VC4 path NE1-NE4. Add NE5 between NE2 and NE3 for capacity expansion. The original configuration remains unchanged. No service is configured on NE5.
In this case, the unprotected chain becomes NE1-NE2-NE5-NE3-NE4, how many VC4 paths can be searched out?

A. 0
B. 1
C. 2
D. 3

正解：D

質問 # 46

質問 # 50
Which of the following descriptions about the DWSS20 board is correct? (Multiple choice)

A. DWSS20 only supports single-wavelength optical power commissioning for the upwave, but not for the downwave
B. The wave adding part realizes that any combination of wavelengths scheduled in any direction is added through any port of AM1~AM20, and output from the OUT port
C. The downwave part implements the signal of the main optical channel received from the IN port, and outputs it through the DM1~DM20 port in any wavelength combination, realizing the scheduling of any wavelength to any port
D. DWSS20 supports optical layer level signal service scheduling with up to 20 dimensional wavelengths

正解：B、C、D
