QUESTION 39
The path method failed to create OCh, which of the following are the possible reasons? (Multiple choice)

There are still unresolved alarms on the board involved in OCh

The wavelength settings at both ends of the source and sink are inconsistent

No service layer path

Some pigtails are not connected

QUESTION 40
Which of the following optical loss alarms will not cause service interruption? (Multiple choice)

CHAZ_LOS

R_LOS

MUT_LOS

OSC LOS

QUESTION 41
MPLS adopts a double-plane structure, which is divided into () and ()

Control plane | Forwarding plane

QUESTION 42
In an OA system, the lower threshold of the receive optical power of a line board (with an APD receiver laser) or the WDM side of an OTU board is the optical module’s receiver sensitivity plus 5 dB.

TRUE

FALSE

For an OA system, the lower threshold of receive optical power of a line board with an APD receiver or the WDM side of an OTU board is the optical module’s receiver sensitivity plus 3 dB, not 5 dB. The 5 dB margin applies mainly to PIN receivers. This distinction is critical because APDs have higher sensitivity and thus require a smaller margin to avoid false alarms or unnecessary protection switching. HCIP-Transmission clearly differentiates these thresholds to ensure proper optical power management and alarm settings in the network.

QUESTION 43
In the process of configuring E-LAN, the MAC address learning mode can be set to SVL and IVL. SVL is independent VLAN learning, and IVL is shared VLAN learning.

True

False

QUESTION 44
Regarding the warning AU-AIS, which one of the following statements is correct.

AU-PTR is composed of HI.H2.H3H3H3. When H1.H2 is all “1”, it will report AU-AIS alarm

AU-PTR is composed of H1.H2.H3H3H3, so when all three are all “1”, the AU-AIS alarm will be reported

When the AU-PTR value is 783, the AU-AIS alarm will be reported

The pointer part of the management unit of the positive structure is all “1”

QUESTION 45
Which of the following are the classification of Ethernet performance test? (Multiple choice)

Network Equipment Performance Verification Test

Network performance testing

Custom Tests

QUESTION 46
The use of QPSK modulation can reduce OSNR requirements and fiber nonlinear hazards, improve dispersion tolerance PMD tolerance, etc.

True

False

QUESTION 47
In the WDM system, if the TTI to be sent by the SM layer is inconsistent with the TTI to be received, an ( ) alarm will be reported.

OTUK_TIM

QUESTION 48
Which of the following are the basic principles of WDM system fault location? (Multiple choice)

Two-way first, then one-way

High level first, then low level

First single wave, then multiple waves

Locate external first, then transmit

QUESTION 49
In the WDM system, troubleshooting generally follows the principles of external first and then internal, first network and then network element, first () and then one-way, first advanced and then (), and first multi-wave and then single-wave.

Two-way | low-level

QUESTION 50
When configuring the basic properties of the Ethernet interface of the EM20 single board, the default value adopted for the “maximum frame length” is?

1522

1491

1490

9600

QUESTION 51
Which of the following options are commonly used instruments or tools in WDM network commissioning? (Multiple choice)

Screwdriver

Optical Spectrum Analyzer

Multimeter

Optical power meter

QUESTION 52
OLA sites can also use ESC.

True

False

QUESTION 53
Which of the following causes a single channel to report the BEFFEC_EXC alarm?

Signals are severely attenuated during line transmission.

The external environment is abnormal.

An optical amplifier board is faulty.

The input optical power of an OTU board is too high or too low.

A single channel reporting the BEFFEC_EXC (Bit Error Forward Error Correction Excess) alarm can be caused by (D) the input optical power of an OTU board being too high or too low. Both extremes can degrade signal quality, causing excessive bit errors. Other causes such as signal attenuation, external environment issues, or faulty optical amplifiers can also impact performance but are less directly linked to BEFFEC_EXC alarms. HCIP-Transmission stresses maintaining proper optical power levels and equipment health to avoid such errors and ensure service quality.

QUESTION 54
The CX plug in OSN550 includes a function board integrated system control and communication (SCC) unit cross-connect unit and clock unit. According to the functions and access functions provided by OSN550. There are many types of function boards.

True

False

QUESTION 55
The smaller the grounding resistance value of the equipment, the better. The smaller the value, the faster the current will be introduced into the ground.

True

False

QUESTION 56
Which of the following descriptions about the business boundary label is correct? (Multiple choice)

When the service demarcation label is User, Ethernet frames with VLAN are not allowed to be inserted.

When the service boundary label is User, it means that the user access mode is Ethernet. PE equipment does not recognize and process U-TAG.

When the industry boundary label is Service, it is not allowed to access the Ethernet frame with VLAN.

When the service demarcation label is Service, it means that the user access mode is VLAN. The PE device will identify and process the TAG according to the PW encapsulation mode.
