HCIP-Transmission V2.0 - H31-341 Exam Practice Test

Question 1

The following description of the alarm, which is correct? (Multiple choice)

A. OTUk-LOM: Multi-frame alignment signal abnormal alarm, multi-frame positioning processing continues the multi-frame out-of-synchronization (o0M) state for 3ms, generating OTUelom alarm.

B. OTUKAIS: OTUK alarm indication signal, the AIS signal is transmitted downstream, indicating that the upstream detected signal is invalid.

C. OTUK-TIM: The OTUK trace identifier is the TTI (Trail Trace Identifier) mismatch. This alarm is generated if the trace identifiers of the peer end and the local end do not match and the TIM detection is enabled during the control process. Compare the API (Access Point Identifiers) in the input signal with the desired API.

D. OTUKBDI: OTUk backwards indication alarm. When the signal detected by the SM segment fails, the value of the BDI byte is 1, and the alarm is reported.

Correct Answer: A,B,C,D

Question 2

The following description of the Directioned scenario, which is correct? (Multiple choice)

A. The wavelength carrying the local service can be transmitted to fixed direction.

B. Directioned scenes are applied to networks that are not ASON.

C. If the current path needs to be adjusted, you must inbound to adjust the fiber connection of the network.

D. When the service needs to be adjusted, or the working path is faulty, the optical crossover can be manually configured to implement flexible scheduling of services.

Correct Answer: A,B,C

Question 3

In the Colored&Directioned scenario of the 4D ROADM, if you want to implement local service scheduling in four directions, how many sets of M40V+D40 are needed?

A. 2

B. 9

C. 1

D. 4

Correct Answer: D

Question 4

The main function of the transport layer in the Huawei ECC protocol stack is _____.

A. Establish and maintain a MAC connection between neighboring network elements.

B. Provide end-to-end communication services to the upper layer

C. Provide data communication services.

D. Establish and maintain an ECC routing table.

Correct Answer: B

Question 5

A. SC1

B. SC2

C. ST2

D. AST2

Correct Answer: A,B

Question 6

As with the STP device, the NG WDM device can practice the network element configuration on the network through pre-configured method.

A. TRUE

B. FALSE

Correct Answer: B

Question 7

The working mode provided by the line fiber quality monitoring function does not include _____.

A. Near-end mode

B. Manual mode

C. Automatic mode

D. Intra-office mode

Correct Answer: C

Question 8

Since the CWDM system does not use an optical amplifier, the focus of the commissioning is whether the light collection of the OTU board is reasonable.

A. TRUE

B. FALSE

Correct Answer: A

Question 9

Which of the following ROADM boards have WSS optical modules? (Multiple Choice)

A. WSM9

B. RDU9

C. WSD9

D. WSMD9

Correct Answer: A,C,D

Question 10

The overhead ratio is a factor that affects the error correction capability of FEC technology. Generally, under the same FEC encoding/decoding algorithm, the higher the overhead ratio, the greater the net coding benefit.

A. TRUE

B. FALSE

Correct Answer: A

Question 11

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

A. TRUE

B. FALSE

Correct Answer: A

Question 12

For the SSM protocol, which of the following statements are correct? (Multiple choice)

A. When the SSM protocol is not enabled, the clock network can only be configured as one-way and cannot be looped.

B. When the standard SSM protocol is started, the clock network can be configured in both directions but cannot be looped.

C. When the extended SSM protocol is started, the clock network can be configured in both directions and can be looped.

D. Whether to start the SSM protocol has little effect on the clock network.

Correct Answer: A,B,C
