HCIP-Transmission V2.0 Questions and Answers

Question 1

If no bit error test is performed on a optical channel for 10 minutes, the local end uses the SDH analyzer to connect to the client-side port on the OTU board, the client-side port on the opposite OTU board need to be self-looped by a fiber. In the case of self-loop, a fixed attenuator must be added.

Options:

A.

True

B.

False

Question 2

In the scenario where the non-convergence OTU processes OTN standard signals, both A and B are WDM sites.The OTU at station A accesses four channels of R_LOS signals on the client side. After being processed in the middle part and on the WDM side of the OTU at station A, the alarm signals are then sent to station B. The ODUk_PM_AIS alarm of the corresponding channel is generated in the middle part of station B. The ODUk_PM_AIS alarm is detected in the client device.

Options:

A.

True

B.

False

Question 3

MPLS APS is a network protection mechanism. It implements service switching by using the MPLS OAM detection function.

Options:

A.

True

B.

False

Question 4

Which of the following is not a precaution after board replacement?

Options:

A.

Record the settings of jumpers and DIP switches on the board.

B.

/For functional units that have backups, check whether the switchover is normal.

C.

Check the indicator blinking status of the board and ensure that the board works properly.

D.

Ensure that no abnormal alarm.

Question 5

In the case of the OptiX OSN equipment, when the standby board is normal, which of the following operations does not cause the active/standby switching of the cross-connect board or clock board?

Options:

A.

Delete the active cross-connect board or clock board logically.

B.

Open the upper and lower ejector levers of the active board at the same time.

C.

Deliver the active/standby switchover command.

D.

Perform a cold reset on the cross-connect or clock board.

Question 6

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

Options:

A.

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.

B.

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.

C.

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.

D.

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.

Question 7

Which of the following standards must be met for the isolation test in the feature test of the multiplexer/demultiplexer?

Options:

A.

<20dB

B.

>25dB

C.

>20dB

D.

<25dB

Question 8

The OSN 1800V supports the following packet protection features:

Options:

A.

Tunnel APS

B.

LAG

C.

TPS

D.

PW APS

Question 9

Which of the following statements about MPLS is wrong?

Options:

A.

MPLS has two planes: control plane and forwarding plane. The control plane is connection-oriented, the forwarding plane is connectionless.

B.

MPLS is not a service or application. It is a standard routing and switching platform that supports various upper-layer protocols and services.

C.

In the packet transport field, the MPLS technology is mainly used to construct tunnels to carry various types of services (for example, TDM, ATM, and Ethernet) transmitted by PWE3 to implement end-to-end transmission of services on packet networks.

D.

MPLS packet forwarding is based on labels.
