質問578、 Which layer is the TCP/UDP protocol located in the TCP/IP protocol?

Application layer

Network layer

Data Link Layer

Transport layer

質問579、 Which of the following costs is not included in the OOS cost?

Optical transmission segment overhead

Optical channel overhead

Optical multiplex section overhead

Optical channel transport unit overhead

質問580、 For nonlinear effect FWM, which of the following processing methods is correct?

Control the input optical power

Controlling Optical Power at Individual Wavelengths

Do not use G, 653 fiber in DWDM system

Using a fiber with a large effective area

質問581、 Pay attention to which of the following when configuring extended ECC? (Multiple choice)

The ECC extension mode of the remote NE must be modified first, and the ECC extension mode of the gateway NE must be modified last.

Avoid communication between the gateway NEs of each subnet through extended ECC.

When setting the ECC extended mode remotely, you must ensure that the settings are correct in order. Otherwise, the disconnected network element will not be able to automatically restore the communication with the network management system, and must be reset on site.

It is not recommended to set the gateway NE as the server. It is recommended to set the NE closest to the gateway NE as the server NE.

質問582、 Which of the following statements about the definition of SDH is correct?

Hierarchies available for asynchronous digital transmission

Hierarchy of standardized digital signals that can be multiplexed asynchronously

Hierarchy of standardized digital signals that can be cross-connected asynchronously

Complete standard digital signal hierarchy provides simultaneous digital transport multiplexing and cross-connection

質問583、 The LER in the MPLS network is a kind of LSR located at the edge of the network.

True

False

質問584、 Which of the following are the limitations of the alarm and performance analysis methods? (Multiple choice)

On-site maintenance personnel cannot know the current operating status of the equipment.

The network management personnel cannot obtain the current alarms of the device, the alarm occurrence time, and the historical alarms of the device.

When some faults occur, there may be no obvious alarms or performance events to report, and sometimes no alarms or performance events can even be found.

In the case of complex networking, services, and fault information, a large number of alarms and performance events may be generated with the occurrence of faults. Due to too many alarms and performance events, maintenance personnel cannot start analysis.

質問585、 () that is, the wavelength carrying local services can be transmitted to a fixed direction. Directionless: The wavelength carrying local services can be transmitted in any direction.

Directed

質問586、 The core device of ROADM is the wavelength selective switch (WSS)

True

False

質問587、 The network element automatically backs up the network element database to the FLASH library every 30 minutes by default.

True

False

質問588、 Which of the following descriptions about the board configuration requirements in the OTN network is correct? (Multiple choice)

The logo on the panel handle should be correct and clear

There are no defects such as insertion marks, holes, and damage at the female end of the board connector

All boards should be inserted to the bottom and the board handles should be fastened properly

The mounting screws on the board must be screwed in place

質問589、 There are three multi-level connection monitoring modes (TCM) of OTN, which ones are correct? (Multiple choice)

Layer mode

Overlap mode

Nested patterns

Through mode

質問590、 A communication network is a system that interconnects geographically dispersed user terminal equipment to realize communication and information exchange. It is mainly composed of user equipment and transmission equipment.

True

False

質問591、 Which of the following modulation mode light sources has the best dispersion tolerance and stability?

Directly modulated light source

PDM-QPSK modulated light source

NZ (Mach-Zehnder) modulated light source

EA electroabsorption modulation light source

質問592、 In daily maintenance scenarios, reset is one of the common operations. Which of the following descriptions about resetting a board is wrong?

Hard reset is similar to plugging and unplugging a single board

Hard reset can be realized through network management

Long press the RST button on the main control board to realize soft reset

Soft reset can only be realized through network management

質問593、 Which of the following descriptions about the MPLS architecture is correct? (Multiple choice)

The control plane is connection-oriented and is responsible for label allocation, establishment of label forwarding tables, establishment and removal of label switching paths, etc.

MPLS uses short and fixed-length labels to encapsulate packet messages, and realizes fast forwarding on the forwarding plane

The forwarding plane is also called the data plane. It is connectionless-oriented and adds and deletes labels to packets. At the same time, the received packet data is forwarded according to the label forwarding table

The main application of MPLS technology is to build a tunnel to carry various types of services (such as TDW, Ethernet) transmitted by PWE3, and realize end-to-end transmission of services in the packet network

質問594、 ODUk SNCP protection subtypes include (), () and ().

SNC/I | SNC/S | SNC/N

質問595、 The optical monitoring channel is set up for the monitoring of WDM optical transmission systems. ITU-T recommends that 1510nm wavelength be used first. Which of the following is the recommended rate?

576Kbit/s

192 Kbit/s

2Mbit/s

64Kbit/s

質問596、 The protection channel of the 1+1 linear multiplex section can be configured with additional services.

True

False
