問題9

When 10-minute error-free test is performed on a certain wavelength division channel, the local end uses the SDH analyzer to interconnect with the client-side interface of the OTU board. The peer OTU client-side interface needs to perform fiber self-loop. When you are self-looping, you must add solid decay.

A. FALSE

B. TRUE

正確答案: B

問題10

In the non-aggregated OTU processing SDH standard signal scenario, both A and B are WDM stations, and the R_Los alarm is detected on the client side of the OTU of the A station. After the alarm is processed on the WDM side of the OTU, the client side of the downstream B station detects and reports the REM_SF alarm, and the B station transmits the signal to the downstream client device and reports the R_LOS alarm to the client device.

A. FALSE

B. TRUE

正確答案: B

問題11

Which of the following is the incorrect description of the internal port properties of the Ethernet board?

A. For the ingress port of the Access attribute, if the input data does not carry the VLAN ID, it is directly transparent.

B. For the inbound port of the Tag Aware attribute, if the input data carries the VLAN ID, transparently receive the data.

C. For the ingress port of the Tag Aware attribute, if the input data does not carry the VLAN ID, discard.

D. For the ingress port for the Access attribute, if the input data carries the VLAN ID, discard.

正確答案: A

問題12

What should be paid attention to when configuring extended ECC? (Multiple Choice)

A. It is not recommended to set the gateway NE as the server. It is recommended to set the NE closest to the gateway NE as the server NE.

B. The ECC extension mode of the remote NE must be modified first, and then the ECC extension mode of the gateway NE is modified.

C. When setting the ECC extended mode remotely, you must ensure that the settings are correct in order. Otherwise, the unmanaged network element will not automatically resume communication with the network management system and must be reset to the site.

D. Avoid communication by extended ECC mode between each subnet gateway network element.

正確答案: A,B,C,D

問題13

Which of the following description of discrete services is correct? (Multiple Choice)

A. Discrete service management requires the U2000 license to have path management functions.

B. A service is searched for a discrete service, indicating that the service is not working properly on the NE side.

C. For the cross-connections, after a path search, either a discrete service or forming a path with other cross-connections, which is impossible to be a discrete service, and forming a path with other cross-connections.

D. Perform path search on the U2000 network management. Cross-connections that do not form a path are called high-bandwidth services.
