Huawei H31-321 Online Questions & Answers

• Question 121:

  SDH equipment supports many protection types. Which of the following statements is false?

  A. It is recommended that the working board be removed for a TPS test two minutes after TPS protection is configured, because it takes a period of time for the protocol to obtain the physical type of the processing board.
  B. When 1+1 protection is configured for the power supply, each PIU board provides 50% of the required DC power. When one PIU board fails, the other also stops providing power.
  C. The 1+1 protection switching between GSCC boards is non-revertive. Services can be switched back only by removing the working board or issuing a switching command on the U2000.
  D. After you insert a GSCC board back, the working GSCC board needs to synchronize data to the newly inserted GSCC board. Wait 5 to 10 minutes until the synchronization is completed. Then restore board active/standby status.
  B. When 1+1 protection is configured for the power supply, each PIU board provides 50% of the required DC power. When one PIU board fails, the other also stops providing power.

• Question 122:

  Which of the following statements are true about fiber-shared virtual path protection?

  A. The VC-4 timeslots of an optical path allocated to an MSP ring and those allocated for an SNCP ring must be different.
  B. When the VC-4 timeslots of an optical path allocated to both an MSP ring and an SNCP ring are the same, services on the VC-4 timeslots have double protection.
  C. The VC-4 timeslots of an optical path allocated to two MSP rings must be different.
  D. When the VC-4 timeslots of an optical path allocated to two MSP rings are the same, services on the VC-4 timeslots have double protection.
  E. The VC-4 timeslots of an optical path allocated to two SNCP rings must be different.
  F. When the VC-4 timeslots of an optical path allocated to two SNCP rings are the same, services on the VC-4 timeslots have double protection.
  A. The VC-4 timeslots of an optical path allocated to an MSP ring and those allocated for an SNCP ring must be different.
  B. When the VC-4 timeslots of an optical path allocated to both an MSP ring and an SNCP ring are the same, services on the VC-4 timeslots have double protection.
