Q129. Which of the following is the basic requirement of the DWDM system on the light source?

The output wavelength is stable

Using the direct modulation method

Low dispersion tolerance

High transmit power

Q130. Both the SC2 and ST2 boards support the processing and transparent transmission of 1588V2 signals.

True

False

Q131. Which of the following is the overall structure of the WDM system with N-channel wavelength multiplexing? (Multiple choice)

Optical wavelength conversion unit

WDM unit

Optical amplification unit

Monitoring unit

Intersection unit

Q132. What are the source functions of the OTUk layer? (Multiple choice)

Perform BIP-8 calculations

Write SM, GCC, FAS, MFAS and other bytes

Finally generate a complete OTUk frame structure

Overhead bytes written to the OTUk layer

Q133. For Huawei equipment, the NODE ID is the unique identifier of the intelligent network element on the control plane. After the network is configured with intelligent services, the NODE ID will not be modified during construction.

True

False

Q134. For the hybrid transmission system with dispersion compensation, the requirements for the optical power entering the fiber should be consistent with the requirements of the original non-coherent system.

True

False

Q135. In any scenario, hard reset of the main control board will cause service interruption.

True

False

Q136. Which of the following descriptions about MPLS and PWE3 are correct? (Multiple choice)

LSP contains different nodes, divided into Ingress, Transit and Egress, each LSP must contain the above three nodes.

A tag stack is a sorted collection of tags. Theoretically, MPLS labels can be nested infinitely.

Multiple PW channels can be carried on one or more PSN Tunnels.

MS-PW is carried by one PSN tunnel, while SS-PW is carried by multiple PSN tunnel segments.

Q137. Which of the following are the service board types of MSTP equipment? (Multiple choice)

Interface board

Service Processing Board

Service processing board with interface

Auxiliary board

Q138. Which of the following is the common point between the two-fiber bidirectional multiplex section shared protection ring and the four-fiber bidirectional multiplex section protection ring?

Section switching

Agreement required

The multiplex section protocol travels on the protection channel

The network capacity is KSTM-N

Q139. Which of the following descriptions about the requirements for fiber optic deployment is wrong?

Labels at both ends of the fiber are filled in correctly and clearly, in neat positions, and in the same direction

Connection points should be clean

There should be no forced pulling and unnatural bending of the optical fiber layout, and no other cables and objects are pressed on it after deployment

The optical fiber is not free to twitch in the buckle

The connecting parts such as bare boards and flanges must be connected reliably

Q140. The path at the GE level is essentially a path at the Client level.

True

False

Q141. The dispersion caused by the two orthogonal polarization states of signal light having different propagation speeds in the optical fiber is called polarization mode dispersion.

True

False

Q142. For a 9-dimensional site, to realize the Colored&Directionless scene, how many boards do you need to configure at least if all WSMD9 boards are used?

10

8

9

11

Q143. When the main control board is single-configured, which step is required to replace the single board compared to when the main control board is dual-configured?

Download the original configuration data

Make sure that the host software version is consistent before and after the replacement, if not, please upgrade and replace the single board software first.

Consistency check of network management and network element data.

Query the alarms of the board and confirm that the original alarms have been cleared.
