3. In OceanStor V5, one LUN is enough for testing the ultimate performance.

4. The deduplication and compression ratio of each LUN can be viewed on the DeviceManager of Dorado V3 (same with Dorado VG)

5. The full-stripe write technology supported by Dorado can effectively improve SSDs' service life.

6. In OceanStor Dorado V6, one LUN is enough for testing close-to-maximum performance.

7. After the SSD is removed the dirk domain of the OceanStor Dorado V3 (same with Dorado V6) storage system reconstructs data immediately.

8. OceanStor 100D can be deployed on standard universal servers.

9. HyperMetro quorum servers can be deployed on VMs.

10. Which statement about the recommended deployment of the quorum device is true?

11. Which of the following statements about the relationship between HyperMetro and multipathing software is correct?

12. Huawei HyperMetro (active-active) solution supports non-disruptive capacity expansion.

13. Huawei is the only storage vendor that has passed the 9-intensity earthquake resistance certification in China.

14. The entire Dorado V6 series supports front-end and back-end interconnect shared t/0 modules.

15. To configure HyperMetro for LUNs that are carrying host services, you must first stop the host services.

16. Two quorum devices are deployed at the third-place site.

Both quorum devices can be used for arbitration at the same time.

17. A technology evenly distributes workloads to each disk, thereby preventing continuous hot data access from causing a premature failure of some disks. This technology is called

18. What is the purpose of using sequential I/Os to overwrite all LUNs before testing Dorado performance?

19. HyperCDP objects can be used to restore data but cannot be directly mapped to hosts for read and write operations.

20. Which is the technology used for end-to-end protection of data integrity in the industry?

21. The OceanStor Os’s data plane and management plane are isolated from each other. Faults on either plane will not affect the other plane

22. In the test case of front-end interface module redundancy, you must first power off the controller and then the front-end interface module.

23. Which technique is used to protect end-to-end data integrity?

24. In database application scenarios, which is the recommended latency of the active-active (HyperMetro) replication network?

25. The storage system monitors the responses to I/Os delivered to disks. If the responses exceed the upper limit, the RAID group experiences a read degrade to quickly respond to the hosts. This technology is called:

26. The active-active status will be interrupted if a quorum server is faulty.

27. QceanStor Dorado V6 supports SAS SSDs only.

28. Which statement about the ROW technology for OceanStor V5 is true?

29. The OceanStor OS has multiple innovative technologies to improve storage system reliability, including Huawei RAIG2.0+, SmartMatrix2.0, and HypenMetro.

30. Unity XT supports full configuration of NVMe SSDS.

31. Which method can be used to upgrade a Dorado active-active (HyperMetro) solution to a 3DC solution?

32. OceanStor 100D provides inline deduplication.

33. Enabling the Fast Write function of replication links between storage arrays can reduce the amount of data to be transmitted by 50%

34. In static-priority arbitration mode, if the active-active relationships are functional, but all replication links between storage arrays are down, what will happen?

35. Which is the scale-out networking protocol that OceanStor Dorado V6 supports?

36. The system availability is 99.999%, indicating that the annual interruption time of the storage array is about 5 minutes.

37. When performing a controller fault test on the Dorado V6 mission-critical product models, ensure that each controller has a link to the host.

38. Which is NOT a typical application of HyperMetro for SAN?

39. Does incremental EC directly aggregate large objects and affect performance?

40. Which technology does FusionStorage HyperSnap run on?

41. HIS refers to hospital management information system. It collects stores. tarsiers analyze queries and may share patient finance and material information, as well as genetates reports to provide comprehensive and accurate data for hospital leaders and management personnel of each departrnent.

42. Which of the following statements is incorrect about the Active-active architecture of Dorado V6?

43. RAID2.0+ is a block-based virtualization technology. Disks are divided into CKs and CKGs form RAID groups. Therefore, compared with traditional RAID, RAID2.0+ does not require hot spare disks or hot spare space.

44. Which statement about the replication network between storage arrays in an active-active (HyperMetro) network is NOT true?

45. Huawei active-active (HyperMetro) solution must use Huawei UltraPath.

46. 1.Fusion Storage supports the iSCSI protocol only in VMware scenarios.

47. Dorado V6 LUNs have controller ownership.

48. Oceanstor Dorado V6 series includes entry-level mid-range and high-end product models.

49. Huawei is the only storage supplier that has passed the 9 intensity earthquake resistance certification in China.

50. Controllers must be restarted during software NDU upgrade of Dorado V6.
