  11. Users use storage foundation HA cluster software and two Huawei blade servers to build a highly available environment for enterprises to provide important business 7 * 24 hour service. One day due to an abnormal power failure one of the servers can not start normally. When the cluster server is in a wait state what command should be issued?

    • hacf -verify
    • hastart -all
    • net start vcscomms

    You determine that the heartbeat members of the node is not started, you can use /etc/init.d/llt start to try to start it.

    • True
    • False

  13. The water level refers to the percentage of total space used in the node pool, including the high water mark and read-only water level. When the Huawei OceanStor 9000 passes the water level threshold to limit the file storage and migration, which of the following description is wrong:

    • When the used space of the node pool reaches a high water level, the system reports an insufficient capacity alarm. By default, the alarm recovery threshold is 5% lower than the water level. That is, when the used space recovers below 80%, the alarm of insufficient capacity alarm recovery, the alarm threshold and the alarm recovery threshold can be manually modified
    • When the node pool’s used space reaches high water level and spill over is selected, the pool of nodes forbids writing data to any other node pool or specified node pool to write data
    • When the node pool’s used space reaches high water level and no spill over is selected, the pool of nodes forbids writing data, and does not write data like other node pools
    • When the used space of the node pool reaches the read-only watermark, the system reports an alarm. The alarm recovery threshold defaults to 0% lower than the low watermark, read-only report
      Police recovery.

  14. In the N8500 (V200R001) clustered NAS system, when the created file system is used for applications accessing large files sequentially, which of the following is correct?

    • In order to allow clients to access a single file system, N8000 can provide higher bandwidth and capacity, it is recommended to create a striped file system
    • Large file access business is a large IO sequential read and write, choose a smaller size of the strip and block size to provide higher bandwidth
    • From a performance perspective, it is recommended that the total number of files in a single file system be less than 80 million
    • For reliability, the recommended number of file systems is less than 40

  17. Which of the following statement regarding the Huawei disaster recovery solution on the implementation of disaster recovery exercise is wrong?

    • The disaster recovery walkthrough automatically stops the production application and unproduces the production to production host mapping on the deviceManager
    • The application of disaster recovery drill is mainly about the production system to switch to disaster recovery operation, exercise disaster recovery environment is correct
    • After the disaster recovery drills are executed, the replication relationship will be split, and the disaster recovery end will take over the production system running service
    • The Drill process can be normal in the production side to stop the business, a quick move to a disaster recovery operation

  18. In a Huawei OceanStor 9000 V100R001C30, in order to experiment with the video surveillance functions of multiple Huawei OceanStor 9000 product you need to install UniformView software. Which of the following statements is wrong?

    • UniformView software installed by the user can specify a directory, create a UniformView directory in this directory as a mounted root table of Contents
    • The administrator performs a mount command on the UniformView client to mount a different storage domain with the cluster ID and the static IP address
    • UniformView Resolve mount command, in the mount root directory, followed by the creation of a cluster ID name of the directory

  19. Customers purchased 3 RH228H v2 hosts (with LPE12002-AP_8G HBA with 2 FC ports), 2 Oceanstor VIS6600T (a total of eight four-port 8G FC interface card, two 4-port 1GE interface card, two 8-port 1GE switch module), two Huawei OCeanStor S6800T, and 2 Brocade 300 switches to build VIS6600T 4-node cluster and pass two S6800Ts.

    The VIS600T cluster is mirrored. Each of the three hosts needs a standard dual-switch redundancy network connected to the VIS6600T4 node. Each Brocade 300 Fiber Channel switches need to use which number of FC ports?

Based on this, what kind of networking can meet the backup business needs and investment least?

    • GE LAN-free
    • 10GE LAN-free
