TRUE

FALSE

NEW QUESTION 81
In the scenario where the non-convergence OTU processes OTN standard signals, both A and B are WDM sites. After receiving the OTUk_TIM alarm on the client side, the OTU board at station A sends the OTUk_BDI alarm to the upstream. When the TIM follow-up action is disabled, the alarm is no longer transmitted to the downstream. When the TIM follow-up action is enabled, an SF event is generated. The WDM side of the OTU board at station B reports the ODUk_PM_AIS alarm, and the ODUk_PM_AIS alarm is transmitted downstream. The client equipment reports this alarm. After the WDM side of the OTU board at station B receives the OTUk_TIM alarm and the TIM follow-up action is disabled, the alarm is no longer transmitted to the downstream. When the TIM follow-up action is enabled, an SF event is generated. After the client side of station B processes the SF event, the client equipment reports the ODUk_PM_AIS alarm.

False

True

NEW QUESTION 82

NEW QUESTION 83
When configuring the Ethernet Layer 2 attribute, set the Default VLAN ID and VLAN Priority of the untagged frame when the TAG ID is set to Accese or Hybrid. The “VLAN priority” is set according to the QoS of the unified plan.

TRUE

FALSE

NEW QUESTION 84
In the WDM system, after a certain distance of transmission, the optical signal-to-noise ratio of the receiving signal will be reduced to a certain extent. What is the main reason?

Fiber attenuation is too large

Use of the splitter combiner

Use of EDFA

No new fiber is used

NEW QUESTION 85
Which of the following statements about the line fiber quality monitoring performance parameters is wrong?

The pulse width of emitted optical pulses varies according to monitoring modes, and affects the detection distance and measurement precision. A greater pulse width provides a larger dynamic range, longer detection distance and better measurement precision.

When the pulse width increases, the light emitting time increases and consequently a larger energy is obtained. This means that a larger dynamic range can be acquired but also larger dead zones will result.

The total fiber loss will affect the detection distance and the dynamic range is fixed for the same detection mode. Therefore, a larger total fiber loss indicates a smaller detection distance.

Measurement is performed multiple times within the detection time. The average value is obtained based on the measurement results to improve the measurement precision. The actual duration from the time when a detection event starts to the time when the detection results are returned will be longer than the Detection time.

NEW QUESTION 86
Which of the following monitoring boards do not support the processing and transparent transmission of 1588V2 signals? (Multiple choice)

ST2

SC2

SC1

AST2

NEW QUESTION 87
Which of the following description is wrong about the content of the formula for calculating the maximum line rate (N=Ratc/((L+7+1+M)x8))?

L is in standard Ethernet frame length with a minimum value of 64Bytes

M is the frame gap, and the minimum IFG (minimum frame gap) is 8 bytes.

Rate indicates the line rate of the physical layer. If the device port is FE, then Rate=100Mbit/s.

“8” outside the brackets is 1 Byte containing 8 Bits

NEW QUESTION 88
Which of the following scenarios does the meter test apply to? (Multiple choice)

Exclude external issues with the transport device

Equipment docking problem

Locate the faulty board

Equipment performance indicator problem

NEW QUESTION 89
What should I pay attention to when commissioning a 100G and 10G hybrid transmission system? (Multiple Choice)

Pay attention to the mixed spectrum. The spectrum of the 100G signal is wider and looks lower than the 100G signal in the spectrum, but the actual optical power is equivalent.

For a hybrid transmission system with dispersion compensation, the dispersion compensation requirements are consistent with the requirements in a 10G non-coherent system.

In order to accurately measure the optical power of 100G wavelength, it must be debugged using a spectrum analyzer or a MAC card.

The optical power of the 100G signal is recommended to be higher than the optical power of the 10G signal, but not higher than the single-wave nominal value of the optical panel.
