NO.107 For ODUk ring network protection, the following statement is wrong:

For each business, it is bound by the segment ID to achieve the only difference in business

The node where the management point is located can have no business binding

Only one node needs to be configured as a management point in the entire ring

Only working channel services need to be manually configured, and all protection channels are automatically generated

NO.108 In the U2000 dual-system hot backup system, the active site fails and the standby site fails to start. Possible reasons () (multiple choice)

Communication between main and standby is interrupted

Database exception

There is an abnormality in the volume at the standby site

High disk space usage

NO.109 The common models of Qos mainly include Best Effort model, Integrated Service model, Differentiated Service model. Which one is the Differentiated Service model described below?

Forward all services as much as possible, regardless of service category

Classify and mark data streams

Reserve resources for each data stream

Maintain the forwarding status of each data stream

NO.110 The LPT (Link Pass Through) function is used in scenarios where WDM equipment accesses FE/GE/10GE LAN services. The correct statement about LPT is: (multiple choice)

It enables the user equipment to perceive the link status information by turning off and turning on the laser of the wavelength division device, thereby triggering the user equipment to activate the business protection function, and select the main or backup link for communication

From the network level, ALS is similar to the Link Pass Through (Link Pass Through) function. The difference is mainly reflected in the applicable services, fault transmission methods and laser restart mechanism.

The implementation of the LPT function can be divided into port-based LPT and service-based LPT.

By adding overhead bytes supporting the LPT protocol to the WDM side signal frame format, the operating status of the network access point or service network can be monitored.

NO.111 The ODU product label is shown in the picture. Which of the following statements is correct? (multiple choice).

The transmitting frequency of this ODU is located in sub-band A of 7GHz

The transceiver interval of this ODU is 154MHz

This ODU can be used as low station

The receiving frequency range is: 7582-7638MHz

NO.112 The OSN8800 device newly expanded a TN55ND2 board, and it was found that the board could not go online. The following reasons are impossible:

SWDL_AUTOMATCH_INH alarm exists in the main control

SWDL_PKG_ NOBDSOFT alarm exists in the main control

SWDL_CHGMNG_NOMATCH alarm exists in the main control

SWDL_BD_WEAKMATCH alarm exists in the main control

NO.113 What may be the reason why the RAU Raman board cannot gain normally? (multiple choice)

Raman pump is not turned on

The current value of the input optical power is -40dbm

Raman board failure

The return loss is too large

NO.114 If the location of the site is appropriate, ROADM sites and OTM sites composed of M40V/D40 back-to-back can all play the role of OEQ sites for pass-through wavelengths

TRUE

FALSE

NO.115 Swap antennas is to align the main lobes of the antennas at both ends to each other, and the signal strength of the opposite antenna is the largest.

TRUE

FALSE

NO.116 The following description of cluster management, the error is ()

The nodes in the cluster have the same cluster ID

A resource group needs to be online only if all the resource groups it depends on are activated before it can go online; when a resource group is offline, the resource groups it depends on are all offline before it can be offline

VVR must be started before the App, and then closed before the App

VVR group: includes basic resources for VCS operation; ClusterService group: used for data replication control

NO.117 The clock ID can solve the problem of timing loops that may occur. In the following networking, in order to completely solve the clock loop, how many clock IDs need to be set?

NO.118 Regarding the network element package loading package diffusion upgrade, which of the following statements is correct?

Configure activation grouping, gateway NEs and non-gateway NEs cannot be grouped into the same group

The number of network elements for the package diffusion upgrade task does not exceed 15.

The package diffusion software upgrade task may not include the gateway network element

The package diffusion software upgrade can only include at most one gateway network element, and the non-gateway network elements in the task must belong to the same gateway network element.

NO.119 Which of the following descriptions are correct in daily maintenance?

For the convenience of collecting data, if you don’t know the customer, you can directly create a network element user to collect data

Without the authorization of the customer, the network management performs configuration data operations

Unplug and plug the board with the customer’s consent

During the cutover process, it is found that other unrelated network elements report an alarm, but the customer does not know that it will be processed directly

NO.120 Regarding the description of OSS, what is wrong is

The network layer of OSS is above NMS, and NMS is generally used to realize the management function of network element equipment.

OSS system is mainly used to improve the work efficiency of equipment maintenance personnel.

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.

U2000 supports multiple northbound interfaces such as SNMP, TL1, XML, CORBA, etc., which can realize rapid integration with the operator’s OSS system.

NO.121 For WDM networks, the following descriptions are correct

For 10G and 100G mixed transmission networks, you can judge whether the dispersion compensation is consistent with the design according to the performance of 100G

For OAU boards, you can roughly judge the type of DCM module connected to the site according to the upper threshold of nominal gain (dB) on the network management system-the upper threshold of actual gain (dB)

For OAU boards, the type of DCM module connected on site can be roughly judged based on the difference between the output of POUT and the input of BAIN

For 10G and 100G mixed transmission networks, you can judge whether the dispersion compensation is consistent with the design according to the performance of 10G

NO.122 Use the integral method to measure the OSNR value of a 100G signal, read from the OSA, the integrated value of the signal power + noise power in the channel interval is 9.68uW, the integrated value of the noise power in the channel interval is 29.58nW, and the signal center frequency is within 0.1nm. The integrated power is 7.395nW, the OSNR value is ()?

10log [(9.68-0.02958)/0.007395]

10log [(9.68+0.02958)/0.007395]

10log [(9.68-0.007395)/0.02958]

10log [(9.68+0.007395)/0.02958]

NO.123 Regarding the configuration description of the U2000 northbound CORBA interface, what is wrong is

The U2000 northbound CORBA interface and the U2000 server run on the same machine, and the machine configuration is required to be able to install and run the U2000 server, and no additional hardware configuration is required

Set the host address, enter the host name or IP address according to the network management plan and design. The “host” mentioned here refers to the computer that provides CORBA services

The default port numbers of normal mode and SSL mode in the basic configuration of U2000 CORBA are different

In the U2000 CORBA configuration, configure at least one of the filtering virtual network element switch and virtual network element switch collar
