1. Huawei hyperconvergence has the function of adaptive global deduplication and compression, which can provide significant space reduction and reduce user TCO under reasonable resource consumption.
Regarding the implementation process of adaptive global deduplication compression, the correct order is:
1. Write data block
2. Point to the data in the fingerprint table after deduplication
3. Upgrade from chance table to fingerprint table
4. Data Block Fingerprint Entry chance table

2. If Hypermetro adopts the arbiter server mode, which of the following positions will the arbiter server prevent?

3. During the operation of replacing the hard disk, which one of the following is the wrong operation?

4. Which of the following is not a step in the troubleshooting process?

5. The storage capacity required by site A is 2543G, and the storage capacity required by site B is 3000G. The backup data of site B is remotely copied to site A for storage.
Considering the case of replication compression, the compression ratio is 3, what is the back-end storage capacity required by calculation site A?

6. In the HyperMletro active-active data center solution, which of the following statements about the static priority of arbitration against split-brain mode is wrong?

7. The IB protocol network layer provides a routing mechanism for information packets from one substructure to another word structure

8. Which item is wrong in the description of Huawei's hybrid flash storage smartcache pool?

9. SmartMigration can completely migrate the services on the source Lun to the target Lun only when the host service is stopped.

10. In oceantorv3 asynchronous remote replication, what is the minimum time interval that time slice technology can achieve?

11. In the HyperMetro active-active solution, UltraPath multipathing software usually needs to be installed on the host server.

12. What type of cables do Huawei OceanStor V3 series storage use to cascade two storage devices?

13. In the Huawei oceantorv3worn file system, the main user of file signatures verifies the integrity of the file, but when the file is migrated, the fingerprint information cannot be migrated with the file, and the fingerprint information needs to be calculated after the file migration is completed.

14. Which of the following is wrong description about the InfoStamper feature?

15. When an emergency level alarm is generated in the storage system, it is necessary to wait until the business is not busy and take corrective measures to prevent more serious failures.

16. Hyper-converged infrastructure refers to not only resources and technologies such as computing, network, storage and server virtualization, but also backup software, snapshot technology, data deduplication, online data compression and other elements in the same set of unit equipment.

17. The online upgrade method is a highly reliable and high-availability upgrade method that is carried out without business interruption. When the user upgrade cannot interrupt the business, it is better than the online upgrade in batches and has less impact on business performance.

18. When the storage business model is continuous large IO, bandwidth is used as a performance measure.

19. Which of the following statements about eDevLun in the SmartVirtuAIization feature of Huawei OceanStor all-flash storage are wrong?

20. Huawei distributed storage uses general x86 architecture hardware to deploy the Scale-out NAS system. The realization of high concurrency and high performance by all nodes for the entire system data is mainly based on three types of networking types: IB, 10GE and PCIE. Among them, PCIE better network performance, easier to scale and manage.
