NO.116 A path is a transmission entity, which is connected by a pair of “one-way paths” that can simultaneously transmit information in opposite directions between their respective outputs and inputs.

NO.117 After the OTN device to the storage device is opened, the actual service rate is less than 20% of the interface rate. Possible reasons (multiple choice)

NO.118 When the OTN equipment is connected to the Cisco equipment, the amount of CRC error packets on the Cisco equipment interface is relatively large. The impossible reasons are:

NO.119 The TN13FIU board does not support optical power detection, but supports reporting MUT_LOS alarms through alarm synthesis

NO.120 MSTP equipment TDM plane can support 1588V2

NO.121 In the Solaris dual-system hot backup system, using “ls -l” to query the file1 file information is “-rwxr-xr– 2wjm newservice 321 Oct 17 09: 33 file1” The following statement is wrong ()

NO.122 Because the Ethernet port OAM acts on the last kilometer and is used for the Ethernet link between two devices, the protocol stipulates that the message cannot be forwarded by the bridge.

NO.123 An ETH_LOS or LINK_ERR alarm occurs on a single Ethernet port of a multi-interface Ethernet board, and the service is interrupted.The possible reasons are: the working mode of the Ethernet port is not matched or the interface rate is inconsistent, the optical module hardware is faulty, and the possible reasons are?

NO.124 The following about DCN network planning, the error is

NO.125 SOM is an intelligent optical layer management solution, which is only used for single-wave optical power and OSNR detection of coherent 40G and 100G systems

NO.126 Which of the following descriptions of the networking requirements for configuring SOM is wrong ()?

NO.127 #1 and #2 are OTM network elements, point-to-point chain services, 1 channel, OAU light emission +4dbm at station A, -35dbm light at the SC2 board at station #2, -30dbm for the OBU board, and -30dbm for the OTU single board. There is no light on the board, what is the most likely cause of the failure?

NO.128 What’s wrong with the description of the 1+1 protection on the client side?

NO.129 After the 10G system wavelength division commissioning is completed, it is found that the OSNR value of the single wave scanned by the receiving MCA is very good, but the bit error rate before error correction is very poor. The possible reasons are (multiple choices)

NO.130 What are the technologies used in the network of the PTN equipment ad hoc network? (multiple choice)

NO.131 The ring network of the OSN6800 equipment group was newly opened, and ODU1-SNCP/N protection was enabled. The engineer reported that a switch occurred one day and has not been restored, but there is no problem with the optical cable. There is an ODU_SNCP_PS alarm on the corresponding ND2 optical port.
Possible reasons are: (multiple choices)
