質問 1：
Two PIU/APIU boards use the hot backup mode to supply power to the system on the OSN 1800 device, when a PIU/APIU board fails, the system can still work normally.
A. TRUE
B. FALSE
正解：A
質問 2：
The basic principles of STP device fault location are? (Multiple choice)
A. First low speed, then high speed
B. First network, then network element
C. First advanced, then low level
D. First external, then transfer
正解：B,C,D
質問 3：
The E-Line service types supported by the MS-OTN packet device are: (Multiple Choice)
A. Point-to-point transparent transmission of E-Line services
B. E-Line carried by PW
C. E-Line service based on QinQ
D. E-Line service based on VL.AN
正解：A,B,C,D
質問 4：
Which of the following is the data that needs to be collected and saved in the event of a failure? (Multiple Choice)
A. Equipment alarms and performance events
B. Operation log of the network management
C. Configuration data for network elements and boards
D. Running status data of the NE and the board
正解：A,B,C,D
質問 5：
Path method creates OCh failure, what are the possible reasons? (Multiple Choice)
A. Inconsistent wavelength setting at both ends of source and sink
B. No service layer path
C. Some pigtails are not connected
D. There are still unremoved alarms in the boards involved in OCh.
正解：A,B,C
質問 6：
Which of the following description of the extended ECC is correct? (Multiple Choice)
A. Extended ECC recommends to use manual basis, which reduces mutual negotiation between network elements.
B. 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.
C. 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.
D. The scale of the extended ECC network (the sum of the server and the client) must not exceed 8.
