NO.111 Which of the following descriptions of the 100G hybrid transmission system is wrong ()?

Coherent and non-coherent signals (10G, 40G ODB) will affect each other, resulting in a sharp drop in performance, and isolation bands are necessary

40G DQPSK and coherent signals will not affect each other, no isolation band is required

In mixed transmission, the coherent signal starts from the long wavelength, 10G starts from the short wavelength, and the isolation band can be filled with 40G DQPSK wavelength

The mixed transmission cost is related to the number of transmission spans and the width of the isolation band, and has nothing to do with the FEC encoding method

NO.112 The reason why the ODUk_PM_OCI alarm statement is correct (multiple choice)

The board corresponding to the upstream site has an ODUk_PM_OCI alarm

Loopback is set for the corresponding board of the opposite station

The corresponding board of the opposite station is not configured with crossover and the non-intrusive monitoring function is enabled on the local end

This alarm will not cause interruption of the optical interface carrying service

NO.113 The following features can adjust the bandwidth on demand in the application of Ethernet networking, dynamically increase and decrease the members in the VCTRUNK without affecting the business. When a virtual concatenation group member fails, the bandwidth can be quickly adjusted to ensure normal data transmission; when the failed member is restored, the original bandwidth of the virtual concatenation group is automatically restored.

NO.114 NG-SDH equipment allocates ECC channel numbers according to certain principles. For example, by default, first insert a four optical port board in slot 4, the board will be assigned channel numbers 0, 1, 2, 3, and then insert an SL16 board in slot 2, then the board will be The assigned channel number is 4. If the SL16 board in slot 2 is unplugged at this time and a four optical port board is inserted in slot 8, what is the assigned channel number?

5, 6, 7, 8

4, 5, 6, 7

4, 6, 7, 8

Random allocation

NO.115 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

TRUE

FALSE

NO.116 There are two types of E1 signals: Unframed E1 and Framed E1, among which Unframed E1 refers to all time slots as a whole to transmit user data.

TRUE

FALSE

NO.117 In which of the following ways can the network-side transport tunnel of the PTN equipment achieve service isolation? (multiple choice)

MPLS

VLAN

S-VLAN

NO.118 Among the following methods, which is the most effective way to avoid discrete business?

Paths with protected routes need to be tested for fiber breakage or switching to ensure that the configuration is complete and standardized

For services that use command line or network management to configure single-site SDH services, route search must be performed on the network management to ensure that the service configuration is complete and standardized

Circuit scheduling is created and configured using network management end-to-end path management

For cross-network management services, landing through virtual network elements

NO.119 Regarding the interconnection of different circuit boards of OTN equipment, which of the following statements is correct (multiple choice)

TN12ND2 and TN12NS2 can be connected in AFEC mode

TN12ND2 and TN11ND2 can be connected in AFEC mode

TN12ND2 and TN52ND2 can be connected in AFEC mode

TN12ND2 and TN52/53/54/57NQ2 can be connected in AFEC mode

NO.120 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.121 In the Linux system, the directory tree structure and the file system are two different concepts. The file system is the logical way of managing files in the operating system, and the directory tree structure is the physical storage method of files on the disk or partition.

TRUE

FALSE

NO.122 In the U2000 dual-machine installation and commissioning, the operations that can be performed by the ossuser user are ()

When the password is forgotten or the password expires and the dbuser cannot be logged in, the ossuser user can log in to the operating system and use “#passwd dbuser” in the terminal to change the password

When the U2000 License file is modified to DOS format, you can log in as the ossuser user and execute the dos2unix command to convert the U2000 License file format from DOS format to UNIX format

Modify the password of the admin user to log in to the VCS client

On the Solaris or SUSE Unux platform, if you cannot log in to the graphical desktop, you can log in as the ossuser user and use the command line to restore the binary mode database

NO.123 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.

TRUE

FALSE

NO.124 Which of the following statements about OTN reuse and overhead is wrong? ()

Client signals (such as IP/MPLS, Ethernet, SDH signals) are mapped to ODUk as ODU payload plus ODU overhead

ODUk combines OTU overhead and FEC overhead and maps to a standardized optical channel transmission unit to form OTUk

OTN optical layer overhead is non-path-associated overhead, and an independent optical supervisory channel OSC is responsible for transmission.

The overhead of the OTN electrical layer unit is the associated overhead, which is transmitted together with the payload

NO.125 The 1588V2 clock enters the non-tracking working mode, and the alarm CLOCK_NO_TRACE_MODE is reported. What is the possible reason?

Some nodes in the network have activated the SSM protocol, and some of the SSM protocols have not been activated

The original priority table of the system clock is not configured, and the network element uses its own default priority table

In the clock source priority table, all other clock sources except the internal source are missing or the frequency deviation is too large

PTP clock configuration error

NO.126 When planning AM, you need to consider the priority planning of E1. Which of the following options are the planning principles of E1 priority (multiple choice)

The E1 priority function is mainly used in the scenario of Hybrid microwave transmission IMA service. At this time, the guaranteed E1 capacity should be equal to the E1 capacity required by IMA to transmit high-priority services; the full-capacity E1 capacity should be equal to the E1 capacity used by IMA.

When the E1 priority function is enabled, E1 service bandwidth under full capacity ≤ full capacity service bandwidth-guaranteed capacity service bandwidth + E1 service bandwidth under guaranteed capacity.

The priority of the E1 service has nothing to do with the time slot number of the IF board it occupies, but the priority is specified when the cross-connection of the E1 service is configured. There are two types of E1 priority: high and low.

The priority set when an E1 service passes through a multi-hop microwave link can be different.

NO.127 Corresponding to the ISO seven-layer model, Ethernet corresponds to the physical and network layers of the seven-layer model. The Ethernet-defined specifications include the MAC sublayer and physical layer of the data link layer.

TRUE

FALSE

NO.128 When configuring the Ethernet EPLAN service, VB will be created on all the sites above and below the service to realize the function of Layer 2 switching.

TRUE

FALSE

NO.129 The function of PW OAM is basically the same as that of Tunnel. The PW OAM mechanism can effectively detect, confirm and locate defects and faults originating from the PW layer network.
Which of the following functions are not available in PW OAM?
