1. Dorado V3 supports NVMe SSDs

2. Which is the function of BBU?

3. Which of the following functions is NOT supported by the OceanStor F V5?

4. Which of the following has the best random read/write performance for small files?

5. 2200 V3 does not support scale-out.

6. Which of the following NL-SAS disk specifications does OceanStor V5 NOT support?

7. Which of the following is the maximum performance ([email protected]) that OceanStor V5 can achieve?

8. You can migrate data from Dorado V3 to traditional storage.

9. HyperSnap requires a full copy of data.

10. Dorado V3 supports post-process compression. Data can be compressed after being written into SSDs.

11. Each LUN on Dorado V6 is owned by a specific controller.

12. SmartQoS allows preferential response to high-priority services. (True or False?)

13. To reduce costs, general-purpose servers are commonly used for object storage.

14. During the interaction between the server and SAN storage, the server encapsulates data in SCSI commands and implements data interaction through various network transmission protocols.

15. A storage pool is a logical combination of multiple storage tiers. A storage tier is a collection of storage media with the same performance in a storage pool.

16. In NAS cross-protocol access, the Windows permission is the same as the Linux permission.

17. Incremental backup requires the full backup and incremental backup of the last time to fully restore data.

Data reconstruction is slower than that of full backup, resulting in a long restoration period.

19. What is the maximum number of disks supported by the OceanStor 2200 V3?

20. What is the maximum redundancy ratio supported by high-ratio EC?

21. How many cabinets does Huawei OceanStor distributed storage allow to fail?

22. What is the specification of the OceanStor Dorado V6 high-end controller?

23. How many controllers can be used when only one LUN is configured on Dorado V6?

24. SmartTier is a tiering feature of file systems.

What is the granularity of tiered migration?

25. Which protocol is used for interconnection between controllers of OceanStor V5 Kunpeng?

26. Which of the following technologies is not used by Huawei OceanStor SmartQoS?

5 is used. If no requested data is hit in the cache (COW mode), what is the IOPS required by the disk arr….

28. A bank needs to store a large number of images of checks every day due to increasing service volume. The existing storage system cannot meet the capacity requirements, so it now takes much longer to retrieve data.

Which is the most suitable storage system type?

30. Which protocol is not a front-end protocol of SAN?

31. Which statement about storage software is incorrect?

32. Which ascending order of disaster recovery levels is correct?

33. In the medical PACS system, X-ray, MRI, CT, and ultrasound tests generate a large number of image files every day. The file size ranges from 100 KB to 1 MB.

Which Huawei NAS product is recommended?

34. Which indicator indicates the time required for system recovery after a disaster occurs?

35. What is the name of the multi-pathing software of Huawei storage?

37. What advantages does the Huawei 2000 V3 offer to get the most out of fixed investments lower prices motivate customers to buy our products, and achieve project success?

38. 4-in-1 means that 4 protocols are integrated into 1 OceanStor 100D storage system for unified management.

Which 4 protocols are involved?

39. What are vertical industries that require OceanStor distributed storage?

40. What are the major differences between distributed storage and centralized storage?
