최신Huawei Certified Internetwork Expert-Transmission - H12-931-ENU무료샘플문제

A. Switching conditions: MUT_LOS/POWER-DIFF-OVER;

B. APS protocol; no need for the whole network protocol;

C. Protection principle: dual-transmit and selective-receive, single-ended switching, non-recovery by default;

D. When configuring protection, the transceiver of the first port (TO1/RI1) can be configured to work or protection;

A. FALSE

B. TRUE

A. When the status of the PW APS slave protection pair changes, it will not cause the status of the PW APS protection group to change.

B. When the PW APS protection group is switched, its subsidiary protection pair also undergoes the same switching.

C. When the status of the PW APS slave protection pair changes, it will cause the status of the PW APS protection group to change.

D. When the PW APS protection group is switched, its subsidiary protection pairs will not undergo the same switching.

A. CESoPSN protocol

B. GFP protocol

C. SAToP protocol

D. ML-PPP protocol

A. The U2000 northbound CORBA interface and the U2000 server run on the same machine, and the machine configuration is required to be able to install and run the U2000 server, and no additional hardware configuration is required

B. The default port numbers of normal mode and SSL mode in the basic configuration of U2000 CORBA are different

C. Set the host address, enter the host name or IP address according to the network management plan and design. The "host" mentioned here refers to the computer that provides CORBA services

D. In the U2000 CORBA configuration, at least one of the filtering virtual network element switch and virtual network element switch must be configured

A. Convergence layer

B. Core layer

C. Edge access layer

A. Delete delay time

B. Change the rate of STM-1 to STM-4

C. Remove NE4

D. Set HP_UNEQ alarm as SNCP switching trigger condition

A. The power difference between the main and backup channels of the OLP protection group is more than 3dB by default, and the alarm is reported up, and the maximum can be set to 8dB

B. OLP main and standby optical power abnormal threshold exceeds 5dB by default to perform switching, and the threshold range can be set -5~5

C. The ODUk-SNCP protection is superimposed on the OLP protection. In order to avoid secondary switching of the SNCP protection, the delay time can be set in the SNCP protection group

D. In the OTN bearer SDH multiplex section ring networking scenario, in order to avoid simultaneous switching of OLP protection and MSP protection, the delay time can be set in the MSP protection group

A. The purpose of testing the IPA function is to verify that if any fiber is broken in the fiber path included in the IPA, the amplifier included in the IPA can be turned off. After the fiber is restored, the amplifier can be automatically turned on, and The power change is within 0.5dB.

B. After the IPA function is successfully activated, when the amplifier board detects LOS, the optical power of its output port becomes safe optical power

C. IPA function is only applicable to Raman amplifiers, not to ordinary amplifiers

D. Select "Configuration/IPA Management" in the function tree of the NE Manager to configure the IPA start delay value

E. When the fiber interruption is repaired and the IPA cannot be terminated, it may be because the IPA protection group is not configured with the "detection board", only the auxiliary detection board is configured, and the auxiliary detection board reports an alarm that triggers IPA
