QUESTION 59
What are the prerequisites for creating a bidirectional MPLS tunnel? (Multiple Choice)

Users have network administrator user rights of “Administrators” and above

The LSR ID of each NE is correctly configured.

Determine the bandwidth of the MPLS Tunnel

Port properties have been configured correctly

QUESTION 60
Which of the following description of the extended ECC is correct? (Multiple Choice)

Extended ECC recommends to use manual basis, which reduces mutual negotiation between network elements.

The scale of the extended ECC network (the sum of the server and the client) must not exceed 8.

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.

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.

QUESTION 61
When using the OSN8800 T32, if you want to set the ID number of the master and slave sub-racks, which board should be set?

EFI

EFI1

EFI2

SCC

QUESTION 62
The reasons for the discrete business are? (Multiple choice)

The network element side configuration data is not uploaded to the U2000.

The cross-connection configuration on the network element is wrong.

The logical fiber connection of the network element is inconsistent with the physical fiber connection.

There is an outbound subnet service whose source or sink port is not within the scope of network management.

QUESTION 63
The overhead ratio is a factor that affects the error correction capability of the FEC technology. Generally, when the same FEC encoding/decoding algorithm is used, the higher the overhead ratio is, the larger the net coding gain is.

False

True

QUESTION 64
The OTS path refers to the physical fiber connection between two adjacent OM/OD/OA on the main optical path.

TRUE

FALSE

QUESTION 65
In the scenario where the non-convergence OTU processes OTN standard signals, both A and B are WDM sites. After receiving the OTUk_TIM alarm on the client side, the OTU board at station A sends the OTUk_BDI alarm to the upstream. When the TIM follow-up action is disabled, the alarm is no longer transmitted to the downstream. When the TIM follow-up action is enabled, an SF event is generated. The WDM side of the OTU board at station B reports the ODUk_PM_AIS alarm, and the ODUk_PM_AIS alarm is transmitted downstream. The client equipment reports this alarm. After the WDM side of the OTU board at station B receives the OTUk_TIM alarm and the TIM follow-up action is disabled, the alarm is no longer transmitted to the downstream. When the TIM follow-up action is enabled, an SF event is generated. After the client side of station B processes the SF event, the client equipment reports the ODUk_PM_AIS alarm.

False

True

QUESTION 66
In the ROADM, which of the following layer of OTN paths do not need to be manually configured, it can be obtained directly by path search? (Multiple Choice)

OTS

OSC

OMS

OCh

QUESTION 67
In the WDM networking design, as long as there are enough EDFA cascades to compensate for the loss of optical power during transmission. Then the system can transmit a long distance without restriction.

TRUE

FALSE

QUESTION 68
Which of the following statements are wrong about TE links? (Multiple Choice)

The intelligent network element sends its own bandwidth and other information to other intelligent peers in the network through the LSA in the form of a trace. Provide teaching support for routing and planning.

The verification of the TE link occurs before the control channel is established between adjacent nodes.

The TE link path is a resource concept. It can be understood as an optical fiber with bandwidth information and protection attributes, but it does not correspond to the optical fiber. One fiber may correspond to multiple TE links.

The TE link is flooded to the entire network by the LMP protocol. Each intelligent network element saves the TE link information of the entire network.

QUESTION 69
For the whole network error test in the commissioning test, which of the following statement is correct? (Multiple choice)

To ensure the smooth passage of all channel services across the entire network, a 10-minute error prediction is required for each single channel.

The duration of the full channel error test is 20 hours. If the error occurs within 20 hours, it needs to be retested for 20 hours after troubleshooting.

When the single channel error test is performed, the remote end needs to perform hardware loopback on the tributary board client side.

The number of OTU boards or tributary boards connected in series for the whole channel error test is recommended to be no more than 13

QUESTION 70
Dispersion compensation is not required for 40 Gbit/s and 100 Gbit/s coherent systems because the dispersion tolerance of coherent boards is large. NG WDM products do not support hybrid transmission of non-coherent and coherent networks.

True

False

QUESTION 71
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)

Line attenuation is too large

Missing logical fiber between sites

Inconsistent wavelengths of the line boards at both ends of the source and sink

errors in source and sink ports in the site

QUESTION 72
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.

TRUE

FALSE

QUESTION 73
For emergency handling of business interruptions, fault location should be performed as soon as possible, and then the business should be resumed.

TRUE

FALSE
