However, the disaster recovery end of the LUNd database can not be started normally. What is the possible reason? (Multiple choice.)

    • After a snapshot of the LUN of the redundancy site is created, the snapshot is not activated at the same time.
    • Disaster recovery storage side of the database resides in the cache has not been written to the hard disk.
    • When creating a snapshot on the disaster recovery end LUN, the production end is copying data to the disaster recovery end.
    • The production end and disaster recovery end adopt the disaster recovery solution of incremental LUN copy. The incremental data is abnormally interrupted during the synchronization process and has not been repaired.

  12. RAID2.0 has the natural advantage of supporting a smart tier, to accelerate the performance of hot data. Which of the following descriptions about the smart tier performance is correct?

    • During the running of the business, the extent size can be adjusted by the size of the hotspot area to obtain better performance.
    • Literacy ratio in the 1:9 scenario, enabling the smart tier has greatly improved the performance of the business.
    • Smart tier has no effect on host performance during hot data migration.

    • Business performance is not affected.
    • Upper business IO read and write will not have any impact.

  15. The client environment is the HP-UX11i v2 operating system, the HBA is the AD193A, and the operating system comes with the driver. The storage array is Huawei OceanStor V3.

  19. A TV station plans to adopt Huawei OceanStor 9000 as a back-end storage system, with 10 OceanStor 9000 C nodes, planned to be deployed in 4 standard cabinets, with all backends connected to a pair of stacked back-end CE6850 switches. There is no single customer in the existing networking standalone management network. Which of the network IP address planning described below is incorrect?

    • You can plan back-end storage network for 9000 internal communications, without planning gateway address, and front-end network with the same network segment IP address.
    • Oceanstor 9000 front-end network and management network can be considered together, planning for the same network segment.
    • Back-end CE6850 switches need to use four stacked cables for stacking connection to ensure bandwidth requirements
    • The external NTP server address and the OceanStor 9000 front-end network need to communicate to ensure that the OceanStor 9000 system and client applications maintain time synchronization.

  20. Which of the following is not a disaster recovery manual restart configuration necessary to restore the production system (Multiple choice.)

    • Stop the current production business
