1. Which of the following statements about multipart upload of object storage service are correct? (Multiple Choice)

2. Users of object storage service (compatible with OpenStack Swift APIs) are managed and authenticated by the Keystone server. Registering, creating, and deleting an account must also be performed on the Keystone server.

3. Which data protection levels can be configured for an OceanStor 9000 that consists of 10 nodes? (Multiple Choice)

4. The OceanStor 9000 allows the clients using different protocols to access the same directory or file simultaneously. For example, Windows clients (using the CIFS protocol), Linux clients (using the NFS protocol), and Mac OS X clients (using the CIFS protocol or NFS protocol).

5. Which network file sharing protocols are supported by a NAS storage system? (Multiple Choice)

6. In an OceanStor 9000, if the protection level is set to 4+2, three mirrors of metadata will be generated.

7. A NAS storage system supports file system sharing, and the underlying protocol transmits data based on iSCSI.

8. At which layers are the Active-Active DC Disaster Recovery Solution deployed? (Multiple Choice)

9. In the Huawei Active-Active DR Solution, an application's peak write bandwidth is 10 MB's, average write bandwidth is 200 KB/s, average write I/O size is 4 KB, and the bandwidth usage is 70%.
In this scenario, how large bandwidth is required for deploying asynchronous remote replication for the application?

10. In the Huawei Active-Active DC Solution, SQL Server can provide services concurrently at both sites.

11. Which types of deduplication are supported by the Huawei OceanStor All-In-One Backup Solution? (Multiple Choice)

12. During data backup, data may be deduplicated to save space. For example, if data blocks A and B are the same, only one data block is physically stored, and the index corresponding to block A or B is deleted.

13. Which of the following is not covered by the backup policy management?

14. In Huawei OceanStor active-active disaster recovery solution, which of the following links can be used between data centers? (Multiple Choice)

15. DASH Copy is an optimized auxiliary copy technique. In each copy session, DASH Copy copies all data blocks from a source disk library to the target disk library.

16. The disaster recovery feature of a storage system supports an RPO of 30 minutes and an RTO of 15 minutes.
Then, which of the following statements are true? (Multiple Choice)

17. Based on full interconnection of data channels and communication channels, a clustered NAS system employs cluster volume management to manage storage space globally. All nodes in the cluster can access the same storage space using the same volume device name, ensuring block device access consistency.

18. In Huawei OceanStor 9000, a file pool is a collection of files that have specific characteristics. A file pool policy defines rules for storing a file pool in a node pool.

19. When the communication between MDC and OSD is interrupted or the OSD is faulty, the OSD exits the storage pool. Then the OSD out-of-service alarm is reported.
Which of the following are the possible causes of this fault? (Multiple Choice)

20. SmartDedupe of the OceanStor 5300 V3 is supported only by the thin file system.

21. Which of the following statements is true.
A) An eDevLUN is always on a third party device?
B) A mirror copy should come from a different domain than the local LUN?

22. From a Windows client perspective, a NAS looks more like a network drive whereas a SAN looks more like a local drive.

23. Which protocol provides the fastest transfer speed?

24. Which of the following statements is correct?
Statement 1: Manually selecting disks for a disk domain is a risky, therefore unadvised, process.
Statement 2: All LUNs in a disk domain must share the same RAID level.

25. SmartMigration uses LUNS mapped from heterogeneous storage arrays to the local storage array as logical disks (LDs) that can provide storage space for the local storage array and create eDevLUNs that can be mapped to the host on LDs.

26. Because SmartDedupe and SmartCompression can reduce the total required storage spacer, they can also reduce the initial investment.

27. SmartQoS uses Traffic Controls, which in turn consists of: (Multiple Choice)

28. A file protected by WORM cannot be: (Multiple Choice)

29. Which is the basal protocol used by SANs for I/O processing?

30. Which of the following statements about LAN-free and Server-free backup networking is true?
