3. Huawei OceanStor 9000 can notify users of alarms by sending emails and short messages.

   • True
   • False

4. Which of the following statements about the intelligent load balancing feature of Huawei OceanStor 9000 is false?

   • Performance is balanced among all nodes. Capacity cannot be balanced among all nodes.
   • Nodes can be grouped into zones. An independent load balancing policy and an independent domain name can be configured for each zone.
   • Load balancing policies can be based on CPU usage, memory usage, bandwidth usage, node connection count, and/or node capability.
   • Huawei OceanStor 9000 provides load balancing service based on round robin, CPU usage, or node connection count.

5. Huawei OceanStor 9000 employs decentralization. Therefore, the Wushan distributed file does not have performance bottlenecks. As the number of nodes increases, the storage capacity at the computing capability increase linearly, which in turn provides linearly increasing bandwidth and concurrency capabilities for users.

   • True
   • False

6. Which of the following statements about quota and statistics is incorrect?

   • When the bucket capacity reaches its quota, data cannot be written to the bucket.
   • When the bucket capacity of an account reaches its quota, this account cannot write data to the bucket.
   • The available bucket resources include the bucket size, the number, and the number of objects in the bucket.
   • The available bucket resources include the account of quota, the number of buckets, the number of objects, and the total capacity.

7. Which feature of Huawei OceanStor 9000 can provide file system snapshots?

   • InfoLocker
   • InfoStamper
   • InfoProtector
   • InfoEqualizer

8. What key technologies are delivered by the OceanStor 9000 to improve the performance of object storage service? (Choose all that apply.)

   • Concurrent access
   • SMB3 Multichannel
   • High-speed interconnection
   • SSD acceleration

9. Which of the following are not functions of OMS? (Choose all that apply.)

   • Alarm reporting
   • Performance reporting
   • Tenant management
   • Device monitoring

10. After the Hadoop service is interconnected with the OceanStor 9000 through the HDFS API, what data redundancy and protection mechanism is adopted?

    • Duplicate mechanism
    • Erasure Code
    • RAID 2.0+
    • Cubic RAID

11. Which of the following statements about versioning for buckets are correct? (Choose all that apply.)

    • You can check whether the versioning is enabled by viewing its state.
    • You can use versioning to save, query, and restore objects of different versions
    • The versioning state can be configured and queried.
    • Versioning cannot be used to retain and archive data.

12. Which quota types are supported by the InfoAllocator feature of Huawei OceanStor 9000? (Choose all that apply.)

    • Capacity quota
    • File quantity quota
    • Calculation quota
    • Mandatory quota

13. What are the reasons for rapid development of the enterprise cloud storage? (Choose all that apply.)

    • Enterprises have strong demands or resource pooling, shorten product go-to-market time, and reduced cost.
    • Storing service data to the cloud can reduce the possibility of misoperation and malicious theft compared to storing the data on the local PC.
    • Enterprise cloud storage can help improve the performance and reliability of typical or new applications.
    • For typical scenarios such as VSI, VDI, and big data, enterprise cloud storage conserves more storage space, provides larger bandwidth, and enhances compatibility between virtual machines (VMs).

14. Which module or device cannot be replaced by using the OceanStor 9000 FRU replacement tool?

    • Power modules
    • Disks
    • Cables or optical modules
    • I/O modules

15. Before restriping, Huawei OceanStor 9000 determines whether the used space of the node pool in the target tier reaches the read-only watermark. Restriping is implemented only when the used space is lower than read-only watermark.

    • True
    • False

16. Which of the following storage nodes are equipped with one SSD by default as the read cache? (Choose all that apply.)

    • P12
    • P25
    • C36
    • C72

17. Which load balancing mode is not supported by the InfoEqualizer feature of Huawei OceanStor 9000?

    • CPU usage
    • User group
    • Node-connections
    • Node throughput

18. Through project management, role management, and user management, FusionStorage file sharing authentication grants user permissions to access and use storage resources.

    • True
    • False 

19. Which of the following statements about Huawei OceanStor 9000 is false?
