Question 151

Which of the following is the maintenance software supported by Huawei's hybrid flash storage products?

A.OceanStor UltraPath

B.SmartKit

C.BCManager eReplication

D.OceanStor eSDK

Question 152

Erasure code redundancy technology supports higher reliability and more flexible redundancy strategies than traditional RAID algorithms. Which one of the following descriptions of Erasurecode principle is wrong?

A.Calculate M through the ErasureCode algorithm for every N consecutive data blocks

B.When data is written, it is cut into N data blocks with the same size

C.The system stores N+M data blocks in parallel in different nodes

D.In Erasure Code storage mode, the system supports up to M-1 hard drives

Question 153

When selecting the data backup type, which of the following descriptions is wrong?

A.Differential incremental can save storage space to the greatest extent, and the backup window is small.

B.If the backup strategy is a full backup combined with a differential incremental backup, after a system failure, if you want to restore the most recent data, you need to restore the data from the last full backup and all differential incremental backups after the full backup.

C.It is recommended to use a combination of three backup types: full backup, differential incremental backup, and cumulative incremental backup.

D.If there is only cumulative incremental backup in the schedule, but no full backup, all files will be backed up when the cumulative incremental backup is performed for the first time.

Question 154

Regarding the multi-NameNode concurrency characteristics of Huawei's distributed storage products, which of the following statements are correct? (Multiple choice)

A.Multiple Active NameNodes provide metadata services, and the data among multiple nodes is consistent in real time

B.Multi-directory metadata operations, multi-node full concurrency

C.Avoid metadata service interruption caused by traditional HDFS NameNode switching

D.The number of files supported by multiple Active NameNodes is no longer restricted by the memory of a single node

Question 155

The object storage services provided by OceanStor9000 (compatible with Amazon S3 and OpenStack Swift) all provide a unified RESTful API. Clients can access storage nodes through STfulAPI to achieve data storage.

A.False

B.True
